generate: consolidate holos generate component cue/helm

Previously helm and cue components were split into two different
subcommands off the holos generate component command.  This is
unnecessary, I'm not sure why it was there in the first place.  The code
seemed perfectly duplicated.

This patch combines them to focus on the concept of a Component.  It
doesn't matter what kind it is now that it's expected to be run from the
root of the platform repository and drop configuration at the root and
the leaf of the tree.

+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.

+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+## Holos - A Holistic Development Platform
+
+<img width="50%"
+align="right"
+style="display: block; margin: 40px auto;"
+src="https://openinfrastructure.co/blog/2016/02/27/logo/logorectangle.png">
+
+Building and maintaining a software development platform is a complex and time
+consuming endeavour.  Organizations often dedicate a team of 3-4 who need 6-12
+months to build the platform.
+
+Holos is a tool and a reference platform to reduce the complexity and speed up
+the process of building a modern, cloud native software development platform.
+
+- **Accelerate new projects** - Reduce time to market and operational complexity by starting your new project on top of the Holos reference platform.
+- **Modernize existing projects** - Incrementally incorporate your existing platform services into Holos for simpler integration.
+- **Unified configuration model** - Increase safety and reduce the risk of config changes with CUE.
+- **First class Helm and Kustomize support** - Leverage and reuse your existing investment in existing configuration tools such as Helm and Kustomize.
+- **Modern Authentication and Authorization** - Holos seamlessly integrates platform identity and access management with zero-trust beyond corp style authorization policy.
+
+## Quick Installation
+
+```console
+go install github.com/holos-run/holos/cmd/holos@latest
+```
+
+## Docs and Support
+
+The documentation for developing and using Holos is available at: https://holos.run
+
+For discussion and support, [open a discussion](https://github.com/orgs/holos-run/discussions/new/choose).

+```
+
+Package v1alpha2 contains the core API contract between the holos cli and CUE configuration code. Platform designers, operators, and software developers use this API to write configuration in CUE which \`holos\` loads. The overall shape of the API defines imperative actions \`holos\` should carry out to render the complete yaml that represents a Platform.
+
+[Platform](<#Platform>) defines the complete configuration of a platform. With the holos reference platform this takes the shape of one management cluster and at least two workload cluster. Each cluster has multiple [HolosComponent](<#HolosComponent>) resources applied to it.
+
+Each holos component path, e.g. \`components/namespaces\` produces exactly one [BuildPlan](<#BuildPlan>) which in turn contains a set of [HolosComponent](<#HolosComponent>) kinds.
+
+The primary kinds of [HolosComponent](<#HolosComponent>) are:
+
+1. [HelmChart](<#HelmChart>) to render config from a helm chart.
+2. [KustomizeBuild](<#KustomizeBuild>) to render config from [Kustomize](<#Kustomize>)
+3. [KubernetesObjects](<#KubernetesObjects>) to render [APIObjects](<#APIObjects>) defined directly in CUE configuration.
+
+Note that Holos operates as a data pipeline, so the output of a [HelmChart](<#HelmChart>) may be provided to [Kustomize](<#Kustomize>) for post\-processing.

+
+<a name="APIObject"></a>
+## type APIObject {#APIObject}
+
+APIObject represents the most basic generic form of a single kubernetes api object. Represented as a JSON object internally for compatibility between tools, for example loading from CUE.
+
+```go
+type APIObject structpb.Struct
+```
+
+<a name="APIObjectMap"></a>
+## type APIObjectMap {#APIObjectMap}
+
+APIObjectMap represents the marshalled yaml representation of kubernetes api objects. Do not produce an APIObjectMap directly, instead use [APIObjects](<#APIObjects>) to produce the marshalled yaml representation from CUE data, then provide the result to [HolosComponent](<#HolosComponent>).
+
+```go
+type APIObjectMap map[Kind]map[Label]string
+```
+
+<a name="APIObjects"></a>
+## type APIObjects {#APIObjects}
+
+APIObjects represents Kubernetes API objects defined directly from CUE code. Useful to mix in resources to any kind of [HolosComponent](<#HolosComponent>), for example adding an ExternalSecret resource to a [HelmChart](<#HelmChart>).
+
+[Kind](<#Kind>) must be the resource kind, e.g. Deployment or Service.
+
+[Label](<#Label>) is an arbitrary internal identifier to uniquely identify the resource within the context of a \`holos\` command. Holos will never write the intermediate label to rendered output.
+
+Refer to [HolosComponent](<#HolosComponent>) which accepts an [APIObjectMap](<#APIObjectMap>) field provided by [APIObjects](<#APIObjects>).
+
+```go
+type APIObjects struct {
+    APIObjects   map[Kind]map[Label]APIObject `json:"apiObjects"`
+    APIObjectMap APIObjectMap                 `json:"apiObjectMap"`
+}
+```
+
+<a name="BuildPlan"></a>
+## type BuildPlan {#BuildPlan}
+
+BuildPlan represents a build plan for the holos cli to execute. The purpose of a BuildPlan is to define one or more [HolosComponent](<#HolosComponent>) kinds. For example a [HelmChart](<#HelmChart>), [KustomizeBuild](<#KustomizeBuild>), or [KubernetesObjects](<#KubernetesObjects>).
+
+A BuildPlan usually has an additional empty [KubernetesObjects](<#KubernetesObjects>) for the purpose of using the [HolosComponent](<#HolosComponent>) DeployFiles field to deploy an ArgoCD or Flux gitops resource for the holos component.
+
+```go
+type BuildPlan struct {
+    Kind       string        `json:"kind" cue:"\"BuildPlan\""`
+    APIVersion string        `json:"apiVersion" cue:"string | *\"v1alpha2\""`
+    Spec       BuildPlanSpec `json:"spec"`
+}

+<a name="BuildPlanComponents"></a>
+## type BuildPlanComponents {#BuildPlanComponents}
+
+
+

+    KustomizeBuildList    []KustomizeBuild            `json:"kustomizeBuildList,omitempty"`
+}
+```
+
+<a name="BuildPlanSpec"></a>
+## type BuildPlanSpec {#BuildPlanSpec}
+
+BuildPlanSpec represents the specification of the build plan.
+
+```go
+type BuildPlanSpec struct {
+    // Disabled causes the holos cli to take no action over the [BuildPlan].
+    Disabled bool `json:"disabled,omitempty"`
+    // Components represents multiple [HolosComponent] kinds to manage.
+    Components BuildPlanComponents `json:"components,omitempty"`
+}
+```
+
+<a name="Chart"></a>
+## type Chart {#Chart}
+
+Chart represents a helm chart.
+
+```go
+type Chart struct {
+    // Name represents the chart name.
+    Name string `json:"name"`
+    // Version represents the chart version.
+    Version string `json:"version"`
+    // Release represents the chart release when executing helm template.
+    Release string `json:"release"`
+    // Repository represents the repository to fetch the chart from.
+    Repository Repository `json:"repository,omitempty"`
+}
+```
+
+<a name="FileContent"></a>
+## type FileContent {#FileContent}
+
+FileContent represents file contents.
+
+```go
+type FileContent string
+```
+
+<a name="FileContentMap"></a>
+## type FileContentMap {#FileContentMap}
+
+FileContentMap represents a mapping of file paths to file contents. Paths are relative to the \`holos\` output "deploy" directory, and may contain sub\-directories.
+
+```go
+type FileContentMap map[FilePath]FileContent
+```
+
+<a name="FilePath"></a>
+## type FilePath {#FilePath}
+
+FilePath represents a file path.
+
+```go
+type FilePath string
+```
+
+<a name="HelmChart"></a>
+## type HelmChart {#HelmChart}
+
+HelmChart represents a holos component which wraps around an upstream helm chart. Holos orchestrates helm by providing values obtained from CUE, renders the output using \`helm template\`, then post\-processes the helm output yaml using the general functionality provided by [HolosComponent](<#HolosComponent>), for example [Kustomize](<#Kustomize>) post\-rendering and mixing in additional kubernetes api objects.
+
+```go
+type HelmChart struct {
+    HolosComponent `json:",inline"`
+    Kind           string `json:"kind" cue:"\"HelmChart\""`
+
+    // Chart represents a helm chart to manage.
+    Chart Chart `json:"chart"`
+    // ValuesContent represents the values.yaml file holos passes to the `helm
+    // template` command.
+    ValuesContent string `json:"valuesContent"`
+    // EnableHooks enables helm hooks when executing the `helm template` command.
+    EnableHooks bool `json:"enableHooks" cue:"bool | *false"`
+}
+```
+
+<a name="HolosComponent"></a>
+## type HolosComponent {#HolosComponent}
+
+HolosComponent defines the fields common to all holos component kinds. Every holos component kind should embed HolosComponent.
+
+```go
+type HolosComponent struct {
+    // Kind is a string value representing the resource this object represents.
+    Kind string `json:"kind"`

+## type Kind {#Kind}
+
+Kind is a kubernetes api object kind. Defined as a type for clarity and type checking.
+
+```go
+type Kind string
+```
+
+<a name="KubernetesObjects"></a>
+## type KubernetesObjects {#KubernetesObjects}
+
+KubernetesObjects represents a [HolosComponent](<#HolosComponent>) composed of Kubernetes API objects provided directly from CUE using [APIObjects](<#APIObjects>).
+
+```go
+type KubernetesObjects struct {
+    HolosComponent `json:",inline"`
+    Kind           string `json:"kind" cue:"\"KubernetesObjects\""`
+}
+```
+
+<a name="Kustomize"></a>
+## type Kustomize {#Kustomize}
+
+Kustomize represents resources necessary to execute a kustomize build. Intended for at least two use cases:
+
+1. Process a [KustomizeBuild](<#KustomizeBuild>) [HolosComponent](<#HolosComponent>) which represents raw yaml file resources in a holos component directory.
+2. Post process a [HelmChart](<#HelmChart>) [HolosComponent](<#HolosComponent>) to inject istio, patch jobs, add custom labels, etc...
+
+```go
+type Kustomize struct {
+    // KustomizeFiles holds file contents for kustomize, e.g. patch files.
+    KustomizeFiles FileContentMap `json:"kustomizeFiles,omitempty"`
+    // ResourcesFile is the file name used for api objects in kustomization.yaml
+    ResourcesFile string `json:"resourcesFile,omitempty"`
+}
+```
+
+<a name="KustomizeBuild"></a>
+## type KustomizeBuild {#KustomizeBuild}
+
+KustomizeBuild represents a [HolosComponent](<#HolosComponent>) that renders plain yaml files in the holos component directory using \`kubectl kustomize build\`.
+
+```go
+type KustomizeBuild struct {
+    HolosComponent `json:",inline"`
+    Kind           string `json:"kind" cue:"\"KustomizeBuild\""`
+}
+```
+
+<a name="Label"></a>
+## type Label {#Label}
+
+Label is an arbitrary unique identifier internal to holos itself. The holos cli is expected to never write a Label value to rendered output files, therefore use a [Label](<#Label>) then the identifier must be unique and internal. Defined as a type for clarity and type checking.
+
+A Label is useful to convert a CUE struct to a list, for example producing a list of [APIObject](<#APIObject>) resources from an [APIObjectMap](<#APIObjectMap>). A CUE struct using Label keys is guaranteed to not lose data when rendering output because a Label is expected to never be written to the final output.
+
+```go
+type Label string
+```
+
+<a name="Metadata"></a>
+## type Metadata {#Metadata}
+
+Metadata represents data about the holos component such as the Name.
+
+```go
+type Metadata struct {
+    // Name represents the name of the holos component.
+    Name string `json:"name"`
+    // Namespace is the primary namespace of the holos component.  A holos
+    // component may manage resources in multiple namespaces, in this case
+    // consider setting the component namespace to default.
+    //
+    // This field is optional because not all resources require a namespace,
+    // particularly CRD's and DeployFiles functionality.
+    // +optional
+    Namespace string `json:"namespace,omitempty"`
+}
+```
+
+<a name="Platform"></a>
+## type Platform {#Platform}
+
+Platform represents a platform to manage. A Platform resource informs holos which components to build. The platform resource also acts as a container for the platform model form values provided by the PlatformService. The primary use case is to collect the cluster names, cluster types, platform model, and holos components to build into one resource.
+
+```go
+type Platform struct {
+    // Kind is a string value representing the resource this object represents.
+    Kind string `json:"kind" cue:"\"Platform\""`
+    // APIVersion represents the versioned schema of this representation of an object.
+    APIVersion string `json:"apiVersion" cue:"string | *\"v1alpha2\""`
+    // Metadata represents data about the object such as the Name.
+    Metadata PlatformMetadata `json:"metadata"`

+    // Name represents the Platform name.
+    Name string `json:"name"`
+}
+```
+
+<a name="PlatformSpec"></a>
+## type PlatformSpec {#PlatformSpec}
+
+PlatformSpec represents the specification of a Platform. Think of a platform specification as a list of platform components to apply to a list of kubernetes clusters combined with the user\-specified Platform Model.
+
+```go
+type PlatformSpec struct {
+    // Model represents the platform model holos gets from from the
+    // PlatformService.GetPlatform rpc method and provides to CUE using a tag.
+    Model structpb.Struct `json:"model"`
+    // Components represents a list of holos components to manage.
+    Components []PlatformSpecComponent `json:"components"`
+}
+```
+
+<a name="PlatformSpecComponent"></a>
+## type PlatformSpecComponent {#PlatformSpecComponent}
+
+PlatformSpecComponent represents a holos component to build or render.
+
+```go
+type PlatformSpecComponent struct {
+    // Path is the path of the component relative to the platform root.
+    Path string `json:"path"`
+    // Cluster is the cluster name to provide when rendering the component.
+    Cluster string `json:"cluster"`
+}
+```
+
+<a name="Repository"></a>
+## type Repository {#Repository}

+
+```go
+import "github.com/holos-run/holos/api/core/v1alpha3"
+```
+
+Package v1alpha3 contains the core API contract between the holos cli and CUE configuration code. Platform designers, operators, and software developers use this API to write configuration in CUE which \`holos\` loads. The overall shape of the API defines imperative actions \`holos\` should carry out to render the complete yaml that represents a Platform.
+
+[Platform](<#Platform>) defines the complete configuration of a platform. With the holos reference platform this takes the shape of one management cluster and at least two workload cluster. Each cluster has multiple [Component](<#Component>) resources applied to it.
+
+Each holos component path, e.g. \`components/namespaces\` produces exactly one [BuildPlan](<#BuildPlan>) which in turn contains a set of [Component](<#Component>) kinds.
+
+The primary kinds of [Component](<#Component>) are:
+
+1. [HelmChart](<#HelmChart>) to render config from a helm chart.
+2. [KustomizeBuild](<#KustomizeBuild>) to render config from [Kustomize](<#Kustomize>)
+3. [KubernetesObjects](<#KubernetesObjects>) to render [APIObjects](<#APIObjects>) defined directly in CUE configuration.
+
+Note that Holos operates as a data pipeline, so the output of a [HelmChart](<#HelmChart>) may be provided to [Kustomize](<#Kustomize>) for post\-processing.

+
+<a name="APIObject"></a>
+## type APIObject {#APIObject}
+
+APIObject represents the most basic generic form of a single kubernetes api object. Represented as a JSON object internally for compatibility between tools, for example loading from CUE.
+
+```go
+type APIObject structpb.Struct
+```
+
+<a name="APIObjectMap"></a>
+## type APIObjectMap {#APIObjectMap}
+
+APIObjectMap represents the marshalled yaml representation of kubernetes api objects. Do not produce an APIObjectMap directly, instead use [APIObjects](<#APIObjects>) to produce the marshalled yaml representation from CUE data, then provide the result to [Component](<#Component>).
+
+```go
+type APIObjectMap map[Kind]map[InternalLabel]string
+```
+
+<a name="APIObjects"></a>
+## type APIObjects {#APIObjects}
+
+APIObjects represents Kubernetes API objects defined directly from CUE code. Useful to mix in resources to any kind of [Component](<#Component>), for example adding an ExternalSecret resource to a [HelmChart](<#HelmChart>).
+
+[Kind](<#Kind>) must be the resource kind, e.g. Deployment or Service.
+
+[InternalLabel](<#InternalLabel>) is an arbitrary internal identifier to uniquely identify the resource within the context of a \`holos\` command. Holos will never write the intermediate label to rendered output.
+
+Refer to [Component](<#Component>) which accepts an [APIObjectMap](<#APIObjectMap>) field provided by [APIObjects](<#APIObjects>).
+
+```go

+}
+```
+
+<a name="BuildPlan"></a>
+## type BuildPlan {#BuildPlan}
+
+BuildPlan represents a build plan for the holos cli to execute. The purpose of a BuildPlan is to define one or more [Component](<#Component>) kinds. For example a [HelmChart](<#HelmChart>), [KustomizeBuild](<#KustomizeBuild>), or [KubernetesObjects](<#KubernetesObjects>).
+
+A BuildPlan usually has an additional empty [KubernetesObjects](<#KubernetesObjects>) for the purpose of using the [Component](<#Component>) DeployFiles field to deploy an ArgoCD or Flux gitops resource for the holos component.
+
+```go
+type BuildPlan struct {

+## type HelmChart {#HelmChart}
+
+HelmChart represents a holos component which wraps around an upstream helm chart. Holos orchestrates helm by providing values obtained from CUE, renders the output using \`helm template\`, then post\-processes the helm output yaml using the general functionality provided by [Component](<#Component>), for example [Kustomize](<#Kustomize>) post\-rendering and mixing in additional kubernetes api objects.
+
+```go

+    EnableHooks bool `json:"enableHooks" cue:"bool | *false"`
+}
+```
+
+<a name="InternalLabel"></a>
+## type InternalLabel {#InternalLabel}
+
+InternalLabel is an arbitrary unique identifier internal to holos itself. The holos cli is expected to never write a InternalLabel value to rendered output files, therefore use a [InternalLabel](<#InternalLabel>) when the identifier must be unique and internal. Defined as a type for clarity and type checking.
+
+A InternalLabel is useful to convert a CUE struct to a list, for example producing a list of [APIObject](<#APIObject>) resources from an [APIObjectMap](<#APIObjectMap>). A CUE struct using InternalLabel keys is guaranteed to not lose data when rendering output because a InternalLabel is expected to never be written to the final output.

+}
+```
+
+<a name="Platform"></a>
+## type Platform {#Platform}
+
+Platform represents a platform to manage. A Platform resource informs holos which components to build. The platform resource also acts as a container for the platform model form values provided by the PlatformService. The primary use case is to collect the cluster names, cluster types, platform model, and holos components to build into one resource.
+
+```go

+# Try Holos Locally
+
+This guide walks through the process of building and managing a software
+development platform with Holos.  The k3d platform built in this guide is a
+slimmed down version of the larger, more holistic, Holos reference platform.
+
+Holos is different from existing tools in a few important ways.
+
+ 1. Holos provides a **unified configuration model** purpose built to improve on
+ unmodified Helm charts, Kustomize bases, or anything else that produces
+ structured configuration data.
+ 2. Holos all but **eliminates the need to template yaml**, a common source of
+ frustration and errors in production.
+ 3. Holos platforms are **composable** and have breadth.  The toolchain and
+ techniques scale down to one machine and up to multiple clusters across
+ multiple regions.
+ 4. The unified configuration model is well suited to a **Zero Trust security
+ model**.  Platform wide policy configuration is easier to manage with Holos.
+
+---
+
+This guide assumes commands are run locally.  Capitalized terms have specific
+definitions described in the [Glossary](/docs/glossary).
+
+## What you'll need {#Requirements}
+
+You'll need the following tools installed to complete this guide.
+
+1. [holos](/docs/install) - to build the platform.
+2. [helm](https://helm.sh/docs/intro/install/) - to render Holos components that wrap upstream Helm charts.
+3. [k3d](https://k3d.io/#installation) - to provide a k8s api server.
+4. [OrbStack](https://docs.orbstack.dev/install) or [Docker](https://docs.docker.com/get-docker/) - to use k3d.
+5. [kubectl](https://kubernetes.io/docs/tasks/tools/) - to interact with the k8s api server.
+6. [mkcert](https://github.com/FiloSottile/mkcert?tab=readme-ov-file#installation) - to make trusted TLS certificates.
+7. [jq](https://jqlang.github.io/jq/download/) - to fiddle with JSON output.
+
+:::note
+
+Registering an account **is recommended** to try out proper authentication and
+authorization in Holos, but you can complete this guide without signing up.
+
+:::
+
+## Goal {#Goal}
+
+By the end of this guide you'll have built the foundation of a software
+development platform.  The foundation provides Zero Trust security by
+holistically integrating off-the-shelf open source software.
+
+  1. Istio is configured to authenticate and authorize requests using an OIDC
+  ID-Token issued by ZITADEL before requests reach backend services.
+  2. The platform provides single sign-on and role based access control for all
+  services running on the platform.
+
+This guide strives to keep things neat and tidy.  All of the resources are
+located in one k3d cluster and one local Git repository.  If you want to clean
+up at any point, do so with:
+
+```bash
+k3d cluster delete workload
+rm -rf holos-k3d
+```
+
+## Sign In or Out {#Sign-In}
+
+Holos provides integrated authentication and authorization which we'll use in
+this guide to protect a service.  We recommend registering an account to see
+this in action.  Registration also enables you to explore the customizable web
+form that simplifies complex configuration.
+
+If you opt-out, the platform will be configured to use a fake identity in place
+of real id tokens.
+
+<Tabs groupId="registration">
+  <TabItem value="registered" label="Sign In">

+  <TabItem value="unregistered" label="Opt Out">
+    ```bash
+    holos logout
+    ```
+  </TabItem>
+</Tabs>
+
+## Create the Platform {#Create-Platform}
+
+A server-side platform resource in Holos stores the web form used to simplify
+platform wide configuration.
+
+First, initialize an empty Git repository:
+
+```bash
+mkdir holos-k3d
+cd holos-k3d
+git init
+```
+
+<Tabs groupId="registration">
+  <TabItem value="registered" label="Signed In">
+    Use `holos` to make the rpc call to create the server-side platform
+    resource.
+
+    ```bash
+    holos create platform --name k3d --display-name "Try Holos Locally"
+    ```
+  </TabItem>
+  <TabItem value="unregistered" label="Signed Out">
+    Create a blank `platform.metadata.json` file so subsequent holos commands
+    skip rpc calls.
+
+    ```bash
+    touch platform.metadata.json
+    ```
+  </TabItem>
+</Tabs>
+
+### Generate the Platform {#Generate-Platform}
+
+Generate the platform code in the repository root.
+
+```bash
+holos generate platform k3d
+```
+
+Commit the generated platform config to the repository.
+
+```bash
+git add .
+git commit -m "holos generate platform k3d - $(holos --version)"
+```
+
+### Push the Platform Form
+
+Each Holos platform has a Platform Form used to submit top level, platform-wide
+configuration values.  The purpose of the form is to validate configuration
+values and simplify complicated configurations and integrations.
+
+<Tabs groupId="registration">
+  <TabItem value="registered" label="Signed In">
+    Push the Platform Form to publish it.  Browse to the printed URL to view the
+    form.
+
+    ```bash
+    holos push platform form .
+    ```
+  </TabItem>
+  <TabItem value="unregistered" label="Signed Out">
+    You will update the Platform Model locally in a later step so there's
+    nothing to do in this step.  Only signed-in users can push a Platform Form
+    to the Holos web server.
+
+    ```bash
+    # holos push platform form .
+    ```
+  </TabItem>
+</Tabs>
+
+The Platform Form is defined locally in `forms/platform/platform-form.cue`.
+
+On the web it looks like:
+![Platform Form Default Values](./form-pushed.png)
+
+### Update the Platform Model {#Platform-Model}
+
+Holos needs initial, top level configuration values to render the platform.  The
+Platform Model is the term we use for these values.  In this section you will
+configure role based access control by way of updating the Platform Model.
+
+In the k3d platform you're building now, role based access control is
+implemented by asserting against the oidc id token subject.  Update the form
+with the `sub` claim value from your id token.  This will ensure only you have
+access to platform services.
+
+<Tabs groupId="registration">
+  <TabItem value="registered" label="Signed In">
+    Copy and paste the `sub` value into your Platform Form's Subject field.
+
+    ```bash
+    holos login --print-claims --log-level=error | jq -r .sub
+    ```
+
+    After pasting the `sub` value, click Submit on the form.
+  </TabItem>
+  <TabItem value="unregistered" label="Signed Out">
+    You don't have an id token when you're signed out, so there's nothing for
+    you to do in this step.
+
+    ```bash
+    # holos login --print-claims --log-level=error | jq -r .sub
+    ```
+
+    The platform will be configured to assert against the User-Agent header
+    instead.
+  </TabItem>
+</Tabs>
+
+### Pull the Platform Model {#Pull-the-Platform-Model}
+
+The Platform Model needs to be pulled into the local Git repository after the
+form has been submitted. Next, we'll run `holos render` which operates
+exclusively on local files.
+
+Holos stores the Platform Model in the `platform.config.json` file. Holos
+provides this file as input to CUE when rendering the platform.  This file is
+intended to be added to version control.
+
+<Tabs groupId="registration">
+  <TabItem value="registered" label="Signed In">
+    Pull the updated Platform Model into the local repository.
+
+    ```bash
+    holos pull platform model .
+    git add platform.config.json
+    git commit -m "Add platform model"
+    ```
+
+  </TabItem>
+  <TabItem value="unregistered" label="Signed Out">
+    The holos generate platform k3d command created an initial Platform Model in
+    `platform.config.json`.  As a result there's nothing to do in this step.
+
+    ```bash
+    # holos pull platform model .
+    # git add platform.config.json
+    # git commit -m "Add platform model"
+    ```
+  </TabItem>
+</Tabs>
+
+## Render the Platform {#Render-the-Platform}
+
+Holos has everything necessary to render the platform once the
+`platform.config.json` file and the code from `holos generate` are in the
+current directory.
+
+Rendering a platform is the process of iterating over each platform component
+and rendering it into plain yaml. Holos does not apply the resulting manifests.
+Other tools like kubectl, ArgoCD, or Flux are responsible for applying the
+manifests.
+
+```bash
+holos render platform ./platform
+```
+
+The render command writes the manifest files to the `deploy/` directory.  Commit
+the files so they can be applied via GitOps later.
+
+```bash
+git add deploy
+git commit -m "holos render platform ./platform"
+```
+
+:::info[Don't blink, this is where Holos builds the platform]
+
+It usually takes no more than a few seconds.
+
+Rendering the holos reference platform currently results in about 500K lines of
+yaml.  In contrast, roughly 80K lines are produced by this slimmed down k3d
+platform.
+
+We mention this because the scale doesn't matter as much as it does with other
+tools.  Manage millions of lines of configuration with Holos the same way this
+guide manages thousands.  This is made possible by the unique way CUE unifies
+all configuration into one single model.
+
+:::
+
+## Configure DNS {#DNS}
+
+Configure your machine to resolve `*.holos.localhost` to your loopback
+interface.  This is necessary for requests to reach the workload cluster.
+
+<Tabs>
+  <TabItem value="macos" label="macOS" default>
+  Cache sudo credentials.
+
+  Admin access is necessary to setup a local dnsmasq instance and configure
+  macOS's DNS resolver.
+
+  ```bash
+  sudo -v
+  ```
+
+  Resolve *.holos.localhost DNS queries to 127.0.0.1.
+
+  ```bash
+  bash ./scripts/local-dns
+  ```

+  </TabItem>
+  <TabItem value="linux" label="Linux">
+    [NSS-myhostname](http://man7.org/linux/man-pages/man8/nss-myhostname.8.html)
+    ships with many Linux distributions and should resolve *.localhost
+    automatically to 127.0.0.1.
+
+    Otherwise it is installable with:
+
+    ```bash
+    sudo apt install libnss-myhostname
+    ```
+  </TabItem>
+  <TabItem value="windows" label="Windows">
+    Ensure the loopback interface has at least the following names in `C:\windows\system32\drivers\etc\hosts`

+    ```
+  </TabItem>
+</Tabs>
+
+
+## Create the Cluster {#Create-Cluster}
+
+The Workload Cluster is where your applications and services will be deployed.
+In production this is usually an EKS, GKE, or AKS cluster.
+
+:::tip
+
+Holos supports all compliant Kubernetes clusters. Holos was developed and tested
+on GKE, EKS, Talos, k3s, and Kubeadm clusters.
+
+:::
+
+<Tabs>
+  <TabItem value="evaluate" label="Try Holos" default>
+  Use this command when exploring Holos.
+
+  ```bash
+  k3d cluster create workload \
+    --port "443:443@loadbalancer" \
+    --k3s-arg "--disable=traefik@server:0"
+  ```
+
+  </TabItem>
+  <TabItem value="develop" label="Develop Holos">
+  Use this command when developing Holos.
+
+  ```bash
+  k3d registry create registry.holos.localhost --port 5100
+  ```
+
+  ```bash
+  k3d cluster create workload \
+    --registry-use k3d-registry.holos.localhost:5100 \
+    --port "443:443@loadbalancer" \
+    --k3s-arg "--disable=traefik@server:0"
+  ```
+
+  </TabItem>
+</Tabs>
+
+Traefik is disabled because Istio provides the same functionality.
+
+## Apply the Platform Components {#Apply-Platform-Components}
+
+Use `kubectl` to apply each platform component.  In production, it's common to
+fully automate this process with ArgoCD, but we use `kubectl` to the same
+effect.
+
+### Local CA {#Local-CA}
+
+Holos platforms use cert manager to issue tls certificates.  The browser and
+tools we're using need to trust these certificates to work together.
+
+Admin access is necessary for `mkcert` to manage the certificate into your trust
+stores.
+
+```bash
+sudo -v
+```
+
+Manage the local CA and copy the CA key to the workload cluster so that cert
+manager can manage trusted certificates.
+
+```bash
+bash ./scripts/local-ca
+```
+
+:::warning
+
+Take care to run the local-ca script each time you create the workload cluster
+so that Certificates are issued correctly.
+
+:::
+
+
+### Service Mesh
+
+The platform service mesh provides an ingress gateway and connectivity useful
+for observability, reliability, and security.
+
+#### Namespaces
+
+With Holos, components are automatically added to the namespaces component,
+useful for centrally managed policies.
+
+```bash
+kubectl apply --server-side=true -f ./deploy/clusters/workload/components/namespaces
+```
+
+#### Custom Resource Definitions
+
+```bash
+kubectl apply --server-side=true -f ./deploy/clusters/workload/components/gateway-api
+kubectl apply --server-side=true -f ./deploy/clusters/workload/components/istio-base
+```
+
+#### Cert Manager {#cert-manager}
+
+Apply the cert-manager controller.
+
+```bash
+kubectl apply --server-side=true -f ./deploy/clusters/workload/components/cert-manager
+```
+
+Apply the ClusterIssuer which issues Certificate resources using the local
+certificate authority.
+
+```bash
+kubectl -n cert-manager wait pod -l app.kubernetes.io/component=webhook --for=condition=Ready
+kubectl apply --server-side=true -f deploy/clusters/workload/components/local-ca
+kubectl apply --server-side=true -f deploy/clusters/workload/components/certificates
+kubectl -n istio-gateways wait certificate httpbin.holos.localhost --for=condition=Ready
+```
+
+:::warning
+
+The certificate will time out before becoming ready if the [local-ca](#Local-CA)
+script was not run after the cluster was created.
+
+:::
+
+#### Istio {#Istio}
+
+Istio implements the Service Mesh.
+
+```bash
+kubectl apply --server-side=true -f ./deploy/clusters/workload/components/istio-cni
+kubectl apply --server-side=true -f ./deploy/clusters/workload/components/istiod
+kubectl apply --server-side=true -f ./deploy/clusters/workload/components/gateway
+```
+
+Verify the Gateway is programmed and the listeners have been accepted:
+
+```bash
+kubectl -n istio-gateways wait gateway default --for=condition=Accepted
+```
+
+#### httpbin {#httpbin}
+
+httpbin is a simple backend service useful for end-to-end testing.
+
+```bash
+kubectl apply --server-side=true -f deploy/clusters/workload/components/httpbin-backend
+kubectl apply --server-side=true -f deploy/clusters/workload/components/httpbin-routes
+kubectl -n holos-system wait pod -l app.kubernetes.io/instance=httpbin --for=condition=Ready
+```
+
+:::info
+
+Browse to [https://httpbin.holos.localhost/](https://httpbin.holos.localhost/)
+to verify end to end connectivity.  You should see the httpbin index page.
+
+:::
+
+### Authenticating Proxy
+
+The auth proxy is responsible for authenticating browser requests, handling the
+oidc authentication flow, and providing a signed id token to the rest of the
+services in the mesh.
+
+#### Cookie Secret
+
+The auth proxy stores session information in an encrypted cookie.  Generate a
+random cookie encryption Secret and apply.
+
+```bash
+LC_ALL=C tr -dc A-Za-z0-9 </dev/urandom \
+  | head -c 32 \
+  | kubectl create secret generic "authproxy" \
+    --from-file=cookiesecret=/dev/stdin \
+    --dry-run=client -o yaml \
+  | kubectl apply -n istio-gateways -f-
+```
+
+#### Deployment
+
+The auth proxy Deployment receives requests from web browsers and responds with
+an authentication decision.
+
+```bash
+kubectl apply --server-side=true -f deploy/clusters/workload/components/authproxy
+kubectl apply --server-side=true -f deploy/clusters/workload/components/authroutes
+```
+
+<Tabs groupId="registration">
+  <TabItem value="registered" label="Signed In">
+    <Admonition type="info">
+    Verify authentication is working by browsing to
+    [https://httpbin.holos.localhost/holos/authproxy](https://httpbin.holos.localhost/holos/authproxy).
+
+    We want a simple `Authenticated` response.
+
+      <Admonition type="tip">
+      You may need to refresh the page a few times while the platform configures
+      itself.
+      </Admonition>
+    </Admonition>
+
+    Istio will respond with `no healthy upstream` until the pod becomes ready.
+    Wait for the pod to become ready with:
+
+    ```bash
+    kubectl -n holos-system wait pod -l app.kubernetes.io/instance=httpbin --for=condition=Ready
+    ```
+
+    Once authenticated, visit
+    [https://httpbin.holos.localhost/holos/authproxy/userinfo](https://httpbin.holos.localhost/holos/authproxy/userinfo)
+    which returns a subset of claims from your id token.
+
+    <Admonition type="warning">

+  </TabItem>
+  <TabItem value="unregistered" label="Signed Out">
+    The auth proxy will always try to sign you in when you are signed out, so
+    there isn't much to do here.  Please do take a moment to glance at the
+    Signed In tab to see how this would work if you were signed in.
+
+    The `k3d` platform relies on `https://login.holos.run` to issue id tokens.
+    Authorization has been configured against fake request headers instead of
+    the real `x-oidc-id-token` header.
+  </TabItem>
+</Tabs>
+
+### Authorization Policy
+
+Configure authorization policies using attributes of the authenticated request.
+Authorization policies route web requests through the auth proxy and then
+validate all requests against the `x-oidc-id-token` header.
+
+```bash
+kubectl apply --server-side=true -f deploy/clusters/workload/components/authpolicy
+```
+
+Istio make take a few seconds to program the Gateway with the
+AuthorizationPolicy resources.
+
+## Try out Zero Trust
+
+A basic Zero Trust security model is now in place.  The platform authenticates
+and authorizes requests before they reach the backend service.
+

+## Summary
+
+Thank you for taking the time to try out Holos.  In this guide, you built the
+foundation of a software development platform that:
+
+ 1. Provides a unified configuration model with CUE that
+    - Supports unmodified Helm Charts, Kustomize Kustomizations, plain YAML.
+    - Provides a web form to pass top level parameters.
+ 2. Reduces errors by eliminating the need to template unstructured text.
+ 3. Is composable and scales down to a local machine.
+ 4. Provides an way to safely configure broad authentication and authorization
+ policy.
+
+## Next Steps
+
+Dive deeper with the following resources that build on the foundation you have now.
+
+ 1. Explore the [Rendering Process](/docs/concepts#rendering) in Holos.
+ 2. Dive deeper into the [Platform Manifests](./platform-manifests) rendered in this guide.
+ 3. Deploy [ArgoCD](../argocd) onto the foundation you built.
+ 4. Deploy [Backstage](../backstage) as a portal to the integrated platform components.
+
+## Clean-Up

+# Platform Manifests
+
+This document provides an example of how Holos uses CUE and Helm to unify and
+render the platform configuration.  It refers to the manifests rendered in the
+Try Holos Locally guide.
+
+Take a moment to review the manifests `holos` rendered to build the platform.
+
+### ArgoCD Application
+
+Note the Git URL in the Platform Model is used to derive the ArgoCD
+`Application` resource for all of the platform components.
+
+```yaml
+# deploy/clusters/workload/gitops/namespaces.application.gen.yaml
+apiVersion: argoproj.io/v1alpha1
+kind: Application
+metadata:
+  name: namespaces
+  namespace: argocd
+spec:
+  destination:
+    server: https://kubernetes.default.svc
+  project: default
+  source:
+    # highlight-next-line
+    path: /deploy/clusters/workload/components/namespaces
+    # highlight-next-line
+    repoURL: https://github.com/holos-run/holos-k3d.git
+    # highlight-next-line
+    targetRevision: HEAD
+```
+
+One ArgoCD `Application` resource is produced for each Holos component by
+default.  The CUE definition which produces the rendered output is defined in
+`buildplan.cue` around line 222.
+
+:::tip
+
+Note how CUE does not use error-prone text templates, the language is well
+specified and typed which reduces errors when unifying the configuration with
+the Platform Model in the following `#Argo` definition.
+
+:::
+
+```cue
+// buildplan.cue
+
+// #Argo represents an argocd Application resource for each component, written
+// using the #HolosComponent.deployFiles field.
+#Argo: {
+	ComponentName: string
+
+	Application: app.#Application & {
+		metadata: name:      ComponentName
+		metadata: namespace: "argocd"
+		spec: {

+        // highlight-next-line
+				repoURL:        _Platform.Model.argocd.repoURL
+        // highlight-next-line
+				targetRevision: _Platform.Model.argocd.targetRevision
+			}
+		}
+	}
+
+	// deployFiles represents the output files to write along side the component.
+	deployFiles: "clusters/\(_ClusterName)/gitops/\(ComponentName).application.gen.yaml": yaml.Marshal(Application)
+}
+```
+
+### Helm Chart
+
+The `cert-manger` component renders using the upstream Helm chart.  The build
+plan that defines the helm chart to use along with the values to provide looks
+like the following.
+

+# Backstory
+
+Holos is a tool intended to lighten the burden of managing Kubernetes resources.  In 2020 we set out to develop a holistic platform composed from open source cloud native components.  We quickly became frustrated with how each of the major components packaged and distributed their software in a different way.  Many projects choose to distribute their software with Helm charts, while others provide plain yaml files and Kustomize bases.  The popular Kube Prometheus Stack project provides Jsonnet to render and update Kubernetes yaml manifests.

+# Glossary
+
+This page describes the terms used within the context of Holos.
+
+## Platform
+
+In Holos, a Platform is a comprehensive environment configured using the
+Kubernetes resource model. It extends beyond traditional Kubernetes
+functionality by integrating cloud resources through Crossplane, allowing for a
+unified management approach across both Kubernetes and cloud infrastructure. A
+Platform typically consists of one Management Cluster, which handles control and
+secret management, and one or more Workload Clusters, where application
+workloads are deployed and run. This architecture enables a consistent and
+scalable approach to managing diverse resources and services within the
+cloud-native ecosystem.
+
+## Management Cluster
+
+In the context of Holos, a Management Cluster is a special Kubernetes cluster
+that hosts Kubernetes controllers.  For example, cert-manager, Cluster api, and
+Crossplane.  A management cluster manages a single platform.  The primary
+function of this cluster is to securely store and manage secrets, ensuring the
+secure handling of sensitive information such as credentials, API keys, and
+other confidential data. The Management Cluster serves as a centralized and
+secure control plane for the platform, facilitating the orchestration and
+management of other components.
+
+## Workload Cluster
+
+In Holos, a Workload Cluster is a Kubernetes cluster designed to host and run
+application workloads. Unlike the Management Cluster, which focuses on control
+and secret management, Workload Clusters are dedicated to executing the actual
+applications and services. These clusters can vary in size and configuration
+based on the specific needs of the applications they support. Workload Clusters
+leverage Kubernetes' orchestration capabilities to manage the deployment,
+scaling, and operation of containerized applications, providing a flexible and
+scalable environment for running production workloads within the platform.
+
+## Platform Form
+
+In Holos, a Platform Form is a customizable web form defined by JSON data. Each
+platform within Holos has a unique Platform Form, which serves as an interface
+for configuring and managing the platform's settings and resources. Platform
+engineers can customize the Platform Form by modifying the underlying CUE
+(Configuration Unified Engine) code, allowing for tailored configurations that
+meet specific requirements. This flexibility enables platform engineers to
+create a user-friendly and specific interface for managing the platform's
+components and operations.
+
+## Platform Model
+
+In Holos, the Platform Model represents the collection of values submitted
+through the Platform Form. It encapsulates the specific configuration details
+and settings defined by the platform engineers, serving as the blueprint for the
+platform's setup and operation. The Platform Model is essential for translating
+the customized options and parameters from the Platform Form into actionable
+configurations within the Holos ecosystem, ensuring that the platform operates
+according to the specified requirements and guidelines.
+
+## Secret Store
+
+In Holos, a SecretStore is a repository for securely storing and managing
+sensitive data such as passwords, API keys, and other confidential information.
+It is compatible with any secret store supported by the External Secrets
+Operator. By default, the management cluster serves as the SecretStore to
+minimize dependencies and simplify the architecture. This setup ensures that
+secrets are managed in a secure and centralized manner, aligning with the
+overall security framework of the platform.
+
+## Service Mesh
+
+In Holos, a Service Mesh is a dedicated infrastructure layer for managing,
+observing, and securing service-to-service communications within a microservices
+architecture. It typically includes features such as load balancing, traffic
+routing, service discovery, and security policies like mutual TLS and access
+control. The Service Mesh abstracts these functionalities away from the
+application code, providing a centralized control plane for managing the
+interactions between microservices. This facilitates better observability,
+resilience, and security in complex, distributed environments.
+
+## Zero Trust
+
+In the context of Holos and broader security practices, Zero Trust is a security
+model that assumes no implicit trust is granted to any user, system, or
+component inside or outside the network. Instead, every request for access is
+treated as potentially malicious, and verification is required at every stage.
+This model enforces strict identity verification, continuous monitoring, and
+least-privilege access policies.

+
+## Configure DNS {#configure-dns}
+
+Configure your machine to resolve `*.holos.localhost` to your loopback
+interface.  This is necessary for requests to reach the workload cluster.  Save
+this script to a file and execute it.
+
+```bash showLineNumbers
+#! /bin/bash
+#
+
+set -euo pipefail
+
+tmpdir="$(mktemp -d)"
+finish() {
+  [[ -d "$tmpdir" ]] && rm -rf "$tmpdir"
+}
+trap finish EXIT

+# Refer to https://holos.run/docs/tutorial/local/k3d/
+address=/holos.localhost/127.0.0.1
+EOF
+
+if [[ -r /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist ]]; then
+  echo "dnsmasq already configured"
+else
+  sudo cp "$(brew list dnsmasq | grep 'dnsmasq.plist$')" \
+    /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist
+  sudo launchctl unload /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist
+  sudo launchctl load /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist
+  dscacheutil -flushcache
+  echo "dnsmasq configured"
+fi
+
+sudo mkdir -p /etc/resolver
+sudo tee /etc/resolver/holos.localhost <<EOF
+domain holos.localhost
+nameserver 127.0.0.1
+EOF
+sudo killall -HUP mDNSResponder
+
+echo "all done."
+```
+
+## Create the Cluster {#create-the-cluster}
+
+The Workload Cluster is where your applications and services will be deployed.
+In production this is usually an EKS, GKE, or AKS cluster.
+
+:::tip
+
+Holos supports all compliant Kubernetes clusters. Holos was developed and tested
+on GKE, EKS, Talos, k3s, and Kubeadm clusters.
+
+:::
+
+Create a local registry to speed up image builds and pulls.
+
+```bash
+k3d registry create registry.holos.localhost --port 5100
+```
+
+Create the workload cluster configured to use the local registry.
+
+```bash
+k3d cluster create workload \
+  --registry-use k3d-registry.holos.localhost:5100 \
+  --port "443:443@loadbalancer" \
+  --k3s-arg "--disable=traefik@server:0"
+```
+
+Traefik is disabled because Istio provides the same functionality.
+
+## Setup Root CA {#setup-root-ca}
+
+Platforms most often use cert-manager to issue tls certificates.  The browser
+and tools we're using need to trust these certificates to work together.
+Generate a local, trusted root certificate authority with the following script.
+
+Admin access is necessary for `mkcert` to manage the certificate into your trust
+stores.
+
+```bash
+sudo -v
+```
+
+Manage the local CA and copy the CA key to the workload cluster so that cert
+manager can manage trusted certificates.
+
+Save this script to a file and execute it to configure a trusted certificate
+authority.
+
+```bash showLineNumbers
+#! /bin/bash
+#
+
+set -euo pipefail
+
+mkcert --install
+
+tmpdir="$(mktemp -d)"
+finish() {
+  [[ -d "$tmpdir" ]] && rm -rf "$tmpdir"
+}
+trap finish EXIT
+cd "$tmpdir"
+
+# Create the local CA Secret with ca.crt, tls.crt, tls.key
+
+mkdir local-ca
+cd local-ca
+CAROOT="$(mkcert -CAROOT)"
+cp -p "${CAROOT}/rootCA.pem" ca.crt
+cp -p "${CAROOT}/rootCA.pem" tls.crt
+cp -p "${CAROOT}/rootCA-key.pem" tls.key
+kubectl create secret generic --from-file=.  --dry-run=client -o yaml local-ca > ../local-ca.yaml
+cd ..
+
+echo 'type: kubernetes.io/tls' >> local-ca.yaml
+kubectl apply --server-side=true -f- <<EOF
+apiVersion: v1

+  name: cert-manager
+spec:
+  finalizers:
+  - kubernetes
+EOF
+kubectl apply -n cert-manager --server-side=true -f local-ca.yaml
+
+```
+
+:::warning
+
+Take care to run the local-ca script each time you create the workload cluster
+so that Certificates are issued correctly.
+
+:::
+
+## Clean Up {#clean-up}
+
+If you'd like to clean up the resources you created in this guide, remove them
+with:
+
+```bash
+k3d cluster delete workload
+```
+
+## Reset {#reset}
+
+If you'd like to reset to a known good state, execute the [Clean Up](#clean-up)
+section, then [Create the Cluster](#create-the-cluster) and the [Setup Root
+CA](#setup-root-ca) tasks.
+
+## Next Steps
+
+Now that you have a real cluster, apply and explore the manifests Holos renders
+in the [Quickstart](/docs/quickstart) guide.

+
+## Generate the Platform {#Generate-Platform}
+
+Generate the Platform code in the repository root. A Platform refers to the
+entire set of software holistically integrated to provide a software development
+platform for your organization. In this guide, the Platform will include a
+single Component to demonstrate how the concepts fit together.
+
+```bash
+holos generate platform quickstart

+
+Commit the generated platform config to the repository.
+
+<Tabs groupId="commit-platform">

+
+The generate component command creates two files: a leaf file,
+`components/podinfo/podinfo.gen.cue`, and a root file, `podinfo.gen.cue`. Holos
+leverages the fact that [order is
+irrelevant](https://cuelang.org/docs/tour/basics/order-irrelevance/) in CUE to
+register the component with the Platform by adding a file to the root of the Git
+repository. The second file defines the component in the leaf component
+directory.

+the Platform by defining them at the root of the configuration.

+The component deploys to one cluster named `default`. In practice, the same

+## Mix in an ArgoCD Application
+
+We've seen how Holos works with Helm, but we haven't yet explored how Holos
+makes it easier to consistently and safely manage all of the software in a
+Platform.
+
+Holos allows you to easily mix in resources that differentiate your Platform.
+We'll use this feature to mix in an ArgoCD [Application][application] to manage
+the podinfo Component with GitOps. We'll define this configuration in a way that
+can be automatically and consistently reused across all future Components added
+to the Platform.

+In this section, we learned how Holos simplifies mixing resources into
+Components, like an ArgoCD Application. Holos ensures consistency by managing an
+Application resource for every Component added to the Platform through the
+configuration you define in `argocd.cue` at the root of the repository.
+
+## Define Workload Clusters {#workload-clusters}
+
+We've generated a Component to manage podinfo and integrated it with our
+Platform, but rendering the Platform doesn't render podinfo. Podinfo isn't
+rendered because we haven't assigned any Clusters to the workload Fleet.
+
+Define two new clusters, `east` and `west`, and assign them to the workload
+Fleet. Create a new file named `clusters.cue` in the root of your Git repository
+with the following contents:
+
+<Tabs groupId="clusters">
+  <TabItem value="clusters.cue" label="clusters.cue">
+    ```cue showLineNumbers
+    package holos
+
+    // Define two workload clusters for disaster recovery.
+    #Fleets: workload: clusters: {
+      // In CUE _ indicates values are defined elsewhere.
+      east: _
+      west: _
+    }
+    ```
+  </TabItem>
+</Tabs>
+
+This example shows how Holos simplifies configuring multiple clusters with
+similar configuration by grouping them into a Fleet.
+
+:::tip
+Fleets help segment a group of Clusters into one leader and multiple followers
+by designating one cluster as the primary. Holos makes it safer, easier, and
+more consistent to reconfigure which cluster is the primary. The primary can be
+set to automatically restore persistent data from backups, while non-primary
+clusters can be configured to automatically replicate from the primary.
+
+Automatic database backup, restore, and streaming replication is an advanced
+topic enabled by Cloud Native PG and CUE. Check back for a guide on this and
+other Day 2 operations topics.

+## Upgrade a Helm Chart
+
+Holos is designed to ease the burden of Day 2 operations. With Holos, upgrading
+software, integrating new software, and making safe platform-wide configuration
+changes become easier.
+
+Let's upgrade the podinfo Component to see how this works in practice. First,
+update the Component version field to the latest upstream Helm chart version.
+
+<Tabs groupId="gen-podinfo">
+  <TabItem value="command" label="Command">
+    ```bash
+    holos generate component podinfo --component-version 6.6.2
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    generated component
+    ```
+  </TabItem>
+</Tabs>
+
+Remove the cached chart version.
+
+<Tabs groupId="gen-podinfo">
+  <TabItem value="command" label="Command">
+    ```bash
+    rm -rf components/podinfo/vendor
+    ```
+  </TabItem>
+</Tabs>
+
+Now re-render the Platform.
+
+<Tabs groupId="render-platform2">
+  <TabItem value="command" label="Command">
+    ```bash
+    holos render platform ./platform
+    ```
+  </TabItem>
+  <TabItem value="output" label="Output">
+    ```txt
+    rendered components/podinfo for cluster east in 327.10475ms
+    rendered components/podinfo for cluster west in 327.796541ms
+    ```
+  </TabItem>
+</Tabs>
+
+Notice we're still using the upstream chart without modifying it. The Holos
+component wraps around the chart to mix in additional resources and integrate
+the component with the broader Platform.
+
+## Visualize the Changes
+
+Holos makes it easier to see exactly what changes are made and which resources
+will be applied to the API server. By design, Holos operates on local files,
+leaving the task of applying them to ecosystem tools like `kubectl` and ArgoCD.
+This allows platform operators to inspect changes during code review, or before
+committing the change at all.
+
+For example, using `git diff`, we see that the only functional change when
+upgrading this Helm chart is the deployment of a new container image tag to each
+cluster.  Additionally, we can roll out this change gradually by applying it to
+the east cluster first, then to the west cluster, limiting the potential blast
+radius of a problematic change.

+## Recap {#recap}
+
+In this quickstart guide, we learned how Holos makes it easier, safer, and more
+consistent to manage a Platform composed of multiple Clusters and upstream Helm
+charts.
+
+We covered how to:
+
+1. Generate a Git repository for the Platform config.
+2. Wrap the unmodified upstream podinfo Helm chart into a Component.
+3. Render an individual Component.
+4. Mix-in your Platform's unique resources to all Components.  For example, ArgoCD Application resources.
+5. Define multiple similar, but not identical, workload clusters.
+6. Render the manifests for the entire Platform with the `holos render platform` command.
+7. Upgrade a Helm chart to the latest version as an important Day 2 task.
+8. Visualize and surface the details of planned changes Platform wide.
+
+## Dive Deeper
+
+If you'd like to dive deeper, check out the [Schema API][schema] and [Core
+API][core] reference docs. The main difference between the schema and core
+packages is that the schema is used by users to write refined CUE, while the
+core package is what the schema produces for `holos` to execute. Users rarely
+need to interact with the Core API when on the happy path, but can use the core
+package as an escape hatch when the happy path doesn't go where you want.

+# Introduction
+
+⚡️ Holos will help you build your **software development platform in no time.**
+
+💸 Building a software development platform is **time consuming and expensive**.  Spend more time building features for your customers and less time managing your development platform.
+
+💥 Already have a platform?  Add new features and services to your platform easily with Holos.
+
+🧐 Holos is a platform builder. It builds a hollistic software development platform composed of best-of-breed cloud native open source projects.  Holos is also a tool to make it easier to manage cloud infrastructure by providing a typed alternative to yaml templates.
+
+## Features
+
+Holos was built to solve two main problems:
+
+ 1. Building a platform usually takes 3 engineers 6-9 months of effort.  Holos provides a reference platform that enables you to deploy and customize your platform in a fraction of the time.
+ 2. Configuration changes often cause outages.  Existing tools like Helm make it difficult to understand the impact a configuration change will have.  Holos provides a unique, unified configuration model powered by CUE that makes it safer and easier to roll out configuration changes.
+
+A core principle of Holos is that organizations gain value from owning the the platform they build on.  Avoid vendor lock-in, future price hikes, and expensive licensing changes by building on a solid foundation of open source, cloud native computing foundation backed projects.
+
+The following features are built into the Holos reference platform.

+
+:::
+
+- **Continuous Delivery**
+  - Holos builds a GitOps workflow for each application running in the platform.
+  - Developers push changes which are automatically deployed.
+  - Powered by [ArgoCD](https://argo-cd.readthedocs.io/en/stable/)
+- **Identity and Access Management** (IAM)
+  - Holos builds a standard OIDC identity provider for you.
+  - Integrates with your exisitng IAM and SSO system, or works independently.
+  - Powerful customer identity and access management features.
+  - Role based access control.
+  - Powered by [ZITADEL](https://zitadel.com/)
+- **Zero Trust**
+  - Authenticate and Authorize users at the platform layer instead of or in addition to the application layer.
+  - Integrated with observability to measure and alert about problems before customers complain.
+  - Powered by [Istio](https://istio.io/)
+- **Observability**
+  - Holos collects performance and availability metrics automatically, without requiring application changes.
+  - Optional, deeper integration into the application layer.
+  - Distributed Tracing
+  - Logging
+  - Powered by Prometheus, Grafana, Loki, and OpenTelemetry.
+- **Data Platform**
+  - Integrated management of PostgreSQL
+  - Automatic backups
+  - Automatic restore from backup
+  - Quickly fail over across multiple regions
+- **Multi-Region**
+  - Holos is designed to operate in multiple regions and multiple clouds.
+  - Keep customer data in the region that makes the most sense for your business.
+  - Easily cut over from one region to another for redundancy and business continuity.
+

+# Deployment
+
+This document describes how deployment from `main` is configured.
+
+1. Refer to the publish workflow.
+2. Uses a SSH deploy key to:
+3. Clone the holos-infra repo.
+4. Write the image tag to saas/userdata/components/dev-holos-app/images.json
+5. Run holos render platform ./platform
+6. Commit and push the results.
+7. ArgoCD takes over the rollout.
