# CLAUDE.md

|

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||
|
||||
## Project Overview
|
||||
|
||||
Holos is a configuration management tool for Kubernetes that implements the rendered manifests pattern using CUE. It unifies Helm charts, Kustomize bases, and raw Kubernetes manifests into a single, declarative pipeline.
|
||||
|
||||
### Core Flow
|
||||
```
|
||||
Platform → Components → BuildPlan → Generators → Transformers → Validators → Manifests
|
||||
```
|
||||
|
||||
## Key Commands
|
||||
|
||||
```bash
|
||||
# Development
|
||||
make build # Build the binary
|
||||
make install # Install binary (REQUIRED before testing holos commands)
|
||||
make test # Run all tests
|
||||
make fmt # Format Go code
|
||||
make lint # Run linters
|
||||
make coverage # Generate coverage report
|
||||
|
||||
# Documentation
|
||||
make update-docs # Update generated docs
|
||||
make website # Build the documentation website
|
||||
|
||||
# Usage (run 'make install' first to test code changes)
|
||||
holos render platform # Render entire platform
|
||||
holos render component # Render single component
|
||||
holos show buildplans # Show build plans
|
||||
holos init platform # Initialize new platform
|
||||
```
|
||||
|
||||
## Architecture
|
||||
|
||||
### Directory Structure
|
||||
- `/api/` - API definitions (v1alpha5 stable, v1alpha6 in development)
|
||||
- `/cmd/` - CLI entry point
|
||||
- `/internal/cli/` - Command implementations
|
||||
- `/internal/component/` - Component handling logic
|
||||
- `/internal/platform/` - Platform handling logic
|
||||
- `/internal/generate/` - Code generation
|
||||
|
||||
### Key Files
|
||||
- `/internal/cli/render/render.go` - Core render logic
|
||||
- `/internal/component/component.go` - Component processing
|
||||
- `/api/core/v1alpha*/types.go` - API type definitions
|
||||
|
||||
### Component Types
|
||||
1. **Helm** - Wraps Helm charts
|
||||
2. **Kustomize** - Wraps Kustomize bases
|
||||
3. **Kubernetes** - Raw Kubernetes manifests
|
||||
|
||||
## CUE Patterns
|
||||
|
||||
Components are defined in CUE:
|
||||
```cue
|
||||
package holos
|
||||
|
||||
holos: Component.BuildPlan
|
||||
|
||||
Component: #Helm & {
|
||||
Name: "example"
|
||||
Chart: {
|
||||
version: "1.0.0"
|
||||
repository: {
|
||||
name: "example"
|
||||
url: "https://charts.example.com"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
- Unit tests: `*_test.go` files colocated with source
|
||||
- Integration tests: `/cmd/holos/tests/`
|
||||
- Example platforms: `/internal/testutil/fixtures/`
|
||||
- Run single test: `go test -run TestName ./path/to/package`
|
||||
|
||||
## Development Patterns
|
||||
|
||||
1. Error handling: Prefer `errors.Format()` from `/internal/errors/` over `fmt.Errorf()`
|
||||
2. Logging: Use structured `slog`, get logger with `logger.FromContext(ctx)`
|
||||
3. CLI commands: Follow Cobra patterns in `/internal/cli/`
|
||||
4. CUE formatting: Always run `cue fmt` on CUE files
|
||||
5. Go formatting: Always run `go fmt` on go files
|
||||
6. Develop against v1alpha6 packages.
|
||||
7. Commits: Use the package name as the first word in the commit, lower case. Commit without asking permission. Always run `make lint` and `make test` before committing.
|
||||
|
||||
## Version Management
|
||||
|
||||
- Version files: `/version/embedded/{major,minor,patch}`
|
||||
- Bump version: `make bump`
|
||||
- API versions: v1alpha5 (stable), v1alpha6 (development)
|
||||
|
||||
## Key Concepts
|
||||
|
||||
- **Platform**: Top-level configuration containing all components
|
||||
- **Component**: Unit of configuration (DAG of Tasks producing deployment configs for one component)
|
||||
- **TaskSet**: DAG of Tasks (Similar to how make tasks behave)
|
||||
- **BuildPlan**: Instructions for building a component. Deprecated in v1alpha6, use TaskSet instead.
|
||||
- **Generator**: Creates manifests (Helm, Kustomize, etc.) author schema only in v1alpha6
|
||||
- **Transformer**: Modifies generated manifests, author schema only in v1alpha6
|
||||
- **Validator**: Validates final manifests, author schema only in v1alpha6
|
||||
|
||||
## Resources
|
||||
|
||||
- Tutorials: `/doc/md/tutorial/`
|
||||
- Platform templates: `/internal/generate/platforms/`
|
||||
- Test fixtures: `/internal/testutil/fixtures/`
|
||||
- Core schemas: `/api/core/` (Abstraction over low level data pipeline tasks)
|
||||
- Author schemas: `/api/author/` (User facing abstractions over core Schemas)

// # Core API
|
||||
//
|
||||
// Package v1alpha4 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 Core API
|
||||
// is declarative. Each resource represents a desired state necessary for holos
|
||||
// to fully render Kubernetes manifests into plain files.
|
||||
//
|
||||
// The following resources provide important context for the Core API. The
|
||||
// [Author API] is intended for component authors as a convenient adapter for
|
||||
// the Core API resources Holos expects.
|
||||
//
|
||||
// 1. [Technical Overview]
|
||||
// 2. [Quickstart]
|
||||
// 3. [Author API]
|
||||
//
|
||||
// # Platform
|
||||
//
|
||||
// [Platform] defines the complete configuration of a platform. A platform
|
||||
// represents a [Component] collection.
|
||||
//
|
||||
// Inspect a Platform resource holos would process by executing:
|
||||
//
|
||||
// cue export --out yaml ./platform
|
||||
//
|
||||
// # Component
|
||||
//
|
||||
// A [Component] is the combination of CUE code along one path relative to the
|
||||
// platform root directory plus data injected from the [PlatformSpec] via CUE tags.
|
||||
// The platform configuration root is the directory containing cue.mod.
|
||||
//
|
||||
// A [Component] always produces exactly one [BuildPlan].
|
||||
//
|
||||
// # BuildPlan
|
||||
//
|
||||
// A [BuildPlan] contains an [Artifact] collection. A BuildPlan often produces
|
||||
// two artifacts, one containing the fully rendered Kubernetes API resources,
|
||||
// the other containing an additional resource to manage the former with GitOps.
|
||||
// For example, a BuildPlan for a podinfo component produces a manifest
|
||||
// containing a Deployment and a Service, along with a second manifest
|
||||
// containing an ArgoCD Application.
|
||||
//
|
||||
// Inspect a BuildPlan resource holos render component would process by executing:
|
||||
//
|
||||
// cue export --out yaml ./projects/platform/components/namespaces
|
||||
//
|
||||
// # Artifact
|
||||
//
|
||||
// An [Artifact] is one fully rendered manifest file produced from the final
|
||||
// [Transformer] in a sequence of transformers. An Artifact may also be
|
||||
// produced directly from a [Generator], but this use case is uncommon.
|
||||
//
|
||||
// # Transformer
|
||||
//
|
||||
// A [Transformer] takes multiple inputs from prior [Generator] or [Transformer]
|
||||
// outputs, then transforms the data into one output. [Kustomize] is the most
|
||||
// commonly used transformer, though a simple [Join] is also supported.
|
||||
//
|
||||
// 1. [Kustomize] - Patch and transform the output from prior generators or
|
||||
// transformers. See [Introduction to Kustomize].
|
||||
// 2. [Join] - Concatenate multiple prior outputs into one output.
|
||||
//
|
||||
// # Generators
|
||||
//
|
||||
// A [Generator] generates Kubernetes resources. [Helm] and [Resources] are the
|
||||
// most commonly used, often paired together to mix-in resources to an
|
||||
// unmodified Helm chart. A simple [File] generator is also available for use
|
||||
// with the [Kustomize] transformer.
|
||||
//
|
||||
// 1. [Resources] - Generates resources from CUE code.
|
||||
// 2. [Helm] - Generates rendered yaml from a [Chart].
|
||||
// 3. [File] - Generates data by reading a file from the component directory.

# 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.

# Guides
|
||||
|
||||
## Technical Overview
|
||||
|
||||
Please see the [Technical Overview] to learn about Holos. If you're ready to
|
||||
drive in and try Holos, please work through the following guides.
|
||||
|
||||
## Bank of Holos
|
||||
The guides are organized as a progression. We'll use Holos to manage a
|
||||
fictional bank's platform, the Bank of Holos in each of the guides. In doing so
|
||||
we'll take the time to explain the foundational concepts of Holos.
|
||||
|
||||
1. [Quickstart] covers the foundational concepts of Holos.
|
||||
2. [Deploy a Service] explains how to deploy a containerized service using an
|
||||
existing Helm chart. This guide then explains how to deploy a similar service
|
||||
safely and consistently with CUE instead of Helm.
|
||||
3. [Change a Service] covers the day two task of making configuration changes to
|
||||
deployed services safely and consistently.

# Change a Service
|
||||
|
||||
In this guide, we'll explore how Holos supports the frontend development team at [Bank of Holos] in reconfiguring an already deployed service. Along the way, we'll demonstrate how simple configuration changes are made safer with type checking, and how rendering the complete platform provides clear visibility into those changes.
|
||||
|
||||
This guide builds on the concepts covered in the [Quickstart] and [Deploy a Service] guides.
|
||||
|
||||
## What you'll need {#requirements}
|
||||
|
||||
Like our other guides, this guide is intended to be useful without needing to
|
||||
run each command. If you'd like to apply the manifests to a real Cluster,
|
||||
complete the [Local Cluster Guide](/docs/guides/local-cluster) before this
|
||||
guide.
|
||||
|
||||
You'll need the following tools installed to run the commands in this guide.
|
||||
|
||||
1. [holos](/docs/install) - to build the Platform.
|
||||
2. [helm](https://helm.sh/docs/intro/install/) - to render Holos Components that
|
||||
wrap Helm charts.
|
||||
3. [kubectl](https://kubernetes.io/docs/tasks/tools/) - to render Holos
|
||||
Components that render with Kustomize.
|
||||
|
||||
## Fork the Git Repository
|
||||
|
||||
If you haven't already done so, [fork the Bank of
|
||||
Holos](https://github.com/holos-run/bank-of-holos/fork) then clone the
|
||||
repository to your local machine.

## Rename the Bank
|
||||
|
||||
Let's imagine the bank recently re-branded from The Bank of Holos to The
|
||||
Holistic Bank. The software development team responsible for the front end
|
||||
website needs to update the branding accordingly.
|
||||
|
||||
Let's explore how Holos catches errors early, before they land in production,
|
||||
then guides the team to the best place to make a change.
|
||||
|
||||
The bank front end web service is managed by the
|
||||
`projects/bank-of-holos/frontend/components/bank-frontend/` component which
|
||||
refers to the organization display name in `schema.gen.cue`.

The new display name changed the frontend container, but it _also_ affected the
|
||||
app-projects component owned by the platform team.
|
||||
:::
|
||||
|
||||
Submitting a pull request would trigger a code review from the platform
|
||||
engineering team who manages the app-projects component. Let's see how to
|
||||
narrow the change down to limit the scope to the bank's user facing services.
|
||||
All of these services are managed under `projects/bank-of-holos/` Move the
|

`organization.cue` file into this folder to limit the scope of configuration to
|

the the components contained within.

The `BANK_NAME` environment variable will change as we expect, and only the dev

Now that we've pushed the change, let's apply the change to the platform.
|

|

## Apply the Change
|
||||
|
||||
Once we've pushed the change, navigate to the [bank-frontend GitOps
|
||||
Application](https://argocd.holos.localhost/applications/argocd/bank-frontend?view=tree&resource=).
|
||||
We can see the Deployment needs to sync to the desired state we just pushed.
|
||||
|
||||

|
||||
|
||||
Clicking on the frontend Deployment, we see the diff with the change we expect.
|
||||
|
||||

|
||||
|
||||
Sync the change, ArgoCD applies the desired configuration state to the cluster
|
||||
and Kubernetes handles rolling out the updated Deployment resource.
|
||||
|
||||

|
||||
|
||||
Soon, the deployment finishes and the component is in sync again.
|
||||
|
||||

|
||||
|
||||
Finally, let's see if the name actually changed on the website. Navigate to
|
||||
https://bank.holos.localhost/.
|
||||
|
||||

|
||||

||||

||||

|

Thanks for taking the time to work through this guide which covered:
|
||||
|
||||
- How multiple teams could be impacted by defining configuration at the
|
||||
`projects/` path.
|
||||
- How to scope our change to only affect components within the
|
||||
`projects/bank-of-holos/` path, eliminating the impact on other teams.
|
||||
- How CUE can [constrain] values in Holos, increasing safety.
|
||||
- How to handle a [default value] in CUE.
|
||||
- How CUE surfaces the file and line number of _every_ place to look for where a
|
||||
value is defined, making it faster and easier to troubleshoot problems.

# Quickstart
|
||||
|
||||
In this guide, you'll experience how Holos makes the process of operating a
|
||||
Platform safer, easier, and more consistent. We'll use Holos to manage a
|
||||
vendor-provided Helm chart as a Component. Next, we'll mix in our own custom
|
||||
resources to manage the Component with GitOps. Finally, you'll see how Holos
|
||||
makes it safer and easier to maintain software over time by surfacing the exact
|
||||
changes that will be applied when upgrading the vendor's chart to a new version,
|
||||
before they are actually made.
|
||||
|
||||
The [Concepts](/docs/concepts) page defines capitalized terms such as Platform
|
||||
and Component.
|
||||
|
||||
## 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.
|
||||
|
||||
Optionally, if you'd like to apply the rendered manifests to a real Cluster,
|
||||
first complete the [Local Cluster Guide](/docs/guides/local-cluster).
|
||||
|
||||
## Install Holos
|
||||
|
||||
Install Holos with the following command or other methods listed on the
|
||||
[Installation](/docs/install/) page.
|
||||
|
||||
```bash
|
||||
go install github.com/holos-run/holos/cmd/holos@latest
|
||||
```
|
||||
|
||||
## Create a Git Repository
|
||||
|
||||
Start by initializing an empty Git repository. Holos operates on local files
|
||||
stored in a Git repository.
|
||||
|
||||
<Tabs groupId="init">
|
||||
<TabItem value="command" label="Command">
|
||||
```bash
|
||||
mkdir holos-quickstart
|
||||
cd holos-quickstart
|
||||
git init
|
||||
```
|
||||
</TabItem>
|
||||
<TabItem value="output" label="Output">
|
||||
```txt
|
||||
Initialized empty Git repository in /holos-quickstart/.git/
|
||||
```
|
||||
</TabItem>
|
||||
</Tabs>
|
||||
|
||||
This guide assumes you will run commands from the root directory of the Git
|
||||
repository unless stated otherwise.
|
||||
|
||||
## 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 --component-version 6.6.1 flag intentionally installs an older release.
|

You'll see how Holos assists with software upgrades later in this guide.
|
||||
|
||||
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.

repository location.

This chart deploys cleanly without any values provided, but we include an empty

Values struct to show how Holos improves consistency and safety in Helm by

leveraging the strong type-checking in CUE. You can safely pass shared values,
|
||||
such as the organization’s domain name, to all Components across all clusters in
|

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

## Render the Component

||||
helpful when developing a new component.

First, the command caches the Helm chart locally to speed up subsequent
|
||||
renderings. Then, the command runs Helm to produce the output and writes it into
|
||||
the deploy directory.

The component deploys to one cluster named `default`. In practice, the same
|
||||
component is often deployed to multiple clusters, such as `east` and `west` to
|
||||
provide redundancy and increase availability.
|
||||
|
||||
:::tip
|
||||
This example is equivalent to running `helm template` on the chart and saving
|
||||
the output to a file. Holos simplifies this task, making it safer and more
|
||||
consistent when managing many charts.
|

:::

## 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.
|
||||
|
||||
Create a new file named `argocd.cue` in the root of your Git repository with the
|
||||
following contents:

||||
inspecting the rendered output without applying it to a live cluster.

Holos uses the locally cached chart to improve performance and reliability. It

then renders the Helm template output along with an ArgoCD Application resource

for GitOps.

:::tip
|
||||
By defining the ArgoCD configuration at the root, we again take advantage of the

irrelevant](https://cuelang.org/docs/tour/basics/order-irrelevance/) in CUE.
|

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">
|
||||

||||

|
||||
<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.

Holos is designed to surface the _fully rendered_ manifests intended for the

Kubernetes API server, making it easier to see and reason about platform-wide
|

## 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.

# Manage a Project
|
||||
|
||||
In this guide we'll explore how Holos easily, safely, and consistently manages
|
||||
platform resources for teams to develop the projects they're working on.
|
||||
|
||||
Intended Audience: Platform Engineers and Software Engineers.
|
||||
|
||||
Goal is to demonstrate how the platform team can consistently, easily, and
|
||||
safely provide platform resources to software engineers.
|
||||
|
||||
Assumption is software engineers have a container they want to deploy onto the
|
||||
platform and make accessible. We'll use httpbin as a stand-in for the dev
|
||||
team's container.
|
||||
|
||||
Project is roughly equivalent to Dev Team for the purpose of this guide, but in
|
||||
practice multiple teams work on a given project over the lifetime of the
|
||||
project, so we structure the files into projects instead of teams.
|
||||
|
||||
## 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 Helm Components.
|
||||
3. [kubectl](https://kubernetes.io/docs/tasks/tools/) - to render Kustomize Components.
|
||||
|
||||
If you'd like to apply the manifests we render in this guide complete the
|
||||
following optional, but recommended, steps.
|
||||
|
||||
a. Complete the [Local Cluster] guide to set up a local cluster to work with.
|
||||
b. You'll need a GitHub account to fork the repository associated with this
|
||||
guide.
|
||||
|
||||

## Render the Platform
|
||||
|
||||
So we can build the basic platform. Don't dwell on the platform bits.
|
||||
|
||||
## Apply the Manifests
|
||||
|
||||
Deploy ArgoCD, but not any of the Application resources.
|
||||
|
||||
## Browse to ArgoCD
|
||||
|
||||
Note there is nothing here yet.
|
||||
|
||||
## Switch to your Fork
|
||||
|
||||
Note all of the Applications change consistently.
|
||||
|
||||
## Apply the Applications
|
||||
|
||||
Note how ArgoCD takes over management, no longer need to k apply.
|
||||
|
||||
## Create a Project
|
||||
|
||||
Project is a conceptual, not technical, thing in Holos. Mainly about how components are laid out in the filesystem tree.
|
||||
|
||||
We use a schematic built into holos as an example, the platform team could use the same or provide a similar template and instructions for development teams to self-serve.
|
||||
|
||||
## Render the Platform
|
||||
|
||||
Notice:
|
||||
|
||||
1. Project is registered with the platform at the root.
|
||||
2. HTTPRoute and Namespace resources are added close to the root in `projects`
|
||||
3. Deployment and Service resources are added at the leaf in `projects/httpbin/backend`
|
||||
|
||||
## Update the image tag
|
||||
|
||||
Add a basic schematic to demonstrate this. May need to add two new flags for image url and image tag to the generate subcommand, but should just be two new fields on the struct.
|
||||
|
||||
## Dive Deeper
|
||||
|
||||
Set the stage for constraints. Ideas: Limit what resources can be added,
|
||||
namespaces can be operated in, enforce labels, etc...
|
||||
|
||||
Simple, consistent, easy constraints.

# Registration
|
||||
|
||||
Holos leverages a simple web app to collect and store platform attributes with a web form. Register an account with the web app to create and retrieve the platform model.
|
||||
|
||||
```
|
||||
holos register user
|
||||
```
|
||||
|

Holos allows you to customize all of the sections and fields of your platform model.
|
||||
|
||||
:::
|
||||
|
||||
|
||||
## Generate your Platform
|
||||
|
||||
Generate your platform configuration from the holos reference platform embedded in the `holos` executable. Platform configuration is stored in a git repository.
|
||||
|
||||
```bash
|
||||
mkdir holos-infra
|
||||
cd holos-infra
|
||||
holos generate platform holos
|
||||
```
|
||||
|
||||
The generate command writes many files organized by platform component into the current directory
|
||||
|
||||
TODO: Put a table here describing key elements?

||||
:::tip
|
||||
|
||||
Take a peek at `holos generate platform --help` to see other platforms embedded in the holos executable.

||||
:::
|
||||
|
||||
## Push the Platform Form
|
||||
|
||||
```
|
||||
holos push platform form .
|
||||
```
|
||||
|
||||
## Fill in the form
|
||||
|
||||
TODO
|
||||
|
||||
## Pull the Platform Model
|
||||
|
||||
Once the platform model is saved, pull it into the holos-infra repository:
|
||||
|
||||
```
|
||||
holos pull platform model .
|
||||
```
|
||||
|
||||
## Render the Platform
|
||||
|
||||
With the platform model and the platform spec, you're ready to render the complete platform configuration:
|
||||
|
||||
```
|
||||
holos render platform ./platform

# 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.

||||

|

## 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:
|
||||

|
||||
|
||||
### 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

## 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.

|
||||
macOS's DNS resolver.
|
||||
|
||||
```bash
|
||||
sudo -v
|
||||
```
|
||||
|
||||
Resolve *.holos.localhost DNS queries to 127.0.0.1.

## 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.
|
||||
|
||||
:::
|
||||

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
|
||||

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.
|
||||
|
||||
### Browser
|
||||
|
||||
<Tabs groupId="registration">
|
||||
<TabItem value="registered" label="Signed In">
|
||||
The platform has been configured to authorize requests with a `x-oidc-id-token` header.
|
||||
|
||||
1. Verify authentication is working by browsing to [https://httpbin.holos.localhost/dump/request](https://httpbin.holos.localhost/dump/request).
|
||||
- Refresh the page a few times.
|
||||
- The `httpbin` backend pods should echo back the `x-oidc-id-token`
|
||||
header injected by the auth proxy.
|
||||
2. Note the `x-oidc-id-token` header is not sent by your browser but is
|
||||
received by the backend service.
|
||||
- This design reduces the risk of exposing id tokens in the browser.
|
||||
- Browser request size remains constant as more claims are added to id
|
||||
tokens.
|
||||
- Reliability improves because id tokens often overflow request header
|
||||
buffers when they pass through middle boxes across the internet.
|
||||
</TabItem>
|
||||
<TabItem value="unregistered" label="Signed Out">
|
||||
The platform has been configured to authorize requests with a `User-Agent: anonymous` header.
|
||||
|
||||
1. Open an incognito window (Cmd+Shift+N) to verify the platform is
|
||||
enforcing the authorization policy.
|
||||
2. Browse to
|
||||
[https://httpbin.holos.localhost/dump/request](https://httpbin.holos.localhost/dump/request)
|
||||
you should be redirected to the sign in page by the auth proxy.
|
||||
- You **do not** need to register or sign in.
|
||||
- This step verifies the platform is redirecting unauthenticated
|
||||
requests to the identity provider.
|
||||
- Navigate back or close and re-open an incognito window.
|
||||
3. Set your `User-Agent` header to `anonymous` using your browser developer tools.
|
||||
- For Chrome the process is described
|
||||
[here](https://developer.chrome.com/docs/devtools/device-mode/override-user-agent#override_the_user_agent_string).
|
||||
- The purpose is to simulate an authenticated request.
|
||||
4. Browse to
|
||||
[https://httpbin.holos.localhost/dump/request](https://httpbin.holos.localhost/dump/request).
|
||||
- The platform should allow the request through to the backend pod.
|
||||
- `httpbin` should echo back your request which should contain `User-Agent: anonymous`.
|
||||
</TabItem>
|
||||
</Tabs>
|

|
||||
### Command Line
|
||||
|
||||
Verify unauthenticated requests are blocked by default outside the browser.
|
||||
|
||||
```bash
|
||||
curl -I https://httpbin.holos.localhost/dump/request
|
||||
```
|
||||
|
||||
You should receive a `HTTP/2 302` response that redirects to `location:
|
||||
https://login.holos.run` to start the oauth login flow.
|
||||
|
||||
Next, verify authenticated requests are allowed.

💡 It also works with `grpcurl`.
|
||||
|
||||
```bash
|

anonymous` in place of validating the oidc id token.
|
||||
|
||||
💡 Take a moment to click the Signed In tab, I don't want you to miss how
|
||||
cool `$(holos token)` is.
|
||||
|

curl -A anonymous https://httpbin.holos.localhost/dump/request
|
||||
```
|
||||
</TabItem>
|

</Tabs>
|
||||
|
||||
You should receive a response showing the request headers the backend received.
|
||||
|
||||
:::tip
|
||||

## 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
|
||||
|
||||
If you'd like to clean up the resources you created in this guide, remove them
|
||||
with:
|
||||
|
||||
```bash
|
||||
k3d cluster delete workload
|
||||
rm -rf holos-k3d
|
||||
```
|
||||
