-# bootkube-terraform
+# terraform-render-bootstrap
 
-`bootkube-terraform` is a Terraform module that renders [bootkube](https://github.com/kubernetes-incubator/bootkube) assets, just like running the binary `bootkube render`. It aims to provide the same variable names, defaults, features, and outputs.
+`terraform-render-bootstrap` is a Terraform module that renders TLS certificates, static pods, and manifests for bootstrapping a Kubernetes cluster.
+
+## Audience
+
+`terraform-render-bootstrap` is a low-level component of the [Typhoon](https://github.com/poseidon/typhoon) Kubernetes distribution. Use Typhoon modules to create and manage Kubernetes clusters across supported platforms. Use the bootstrap module if you'd like to customize a Kubernetes control plane or build your own distribution.
 
 ## Usage
 
-Use the `bootkube-terraform` module within your existing Terraform configs. Provide the variables listed in `variables.tf` or check `terraform.tfvars.example` for examples.
+Use the module to declare bootstrap assets. Check [variables.tf](variables.tf) for options and [terraform.tfvars.example](terraform.tfvars.example) for examples.
 
 ```hcl
-module "bootkube" {
-  source = "git://https://github.com/dghubble/bootkube-terraform.git"
+module "bootstrap" {
+  source = "git::https://github.com/poseidon/terraform-render-bootstrap.git?ref=SHA"
 
   cluster_name = "example"
   api_servers = ["node1.example.com"]
-  etcd_servers = ["http://127.0.0.1:2379"]
-  asset_dir = "/home/core/clusters/mycluster"
-  experimental_self_hosted_etcd = false
+  etcd_servers = ["node1.example.com"]
 }
 ```
 
-Alternately, use a local checkout of this repo and copy `terraform.tfvars.example` to `terraform.tfvars` to generate assets without an existing terraform config repo.
-
-Generate the bootkube assets.
+Generate the assets.
 
 ```sh
-terraform get
+terraform init
 terraform plan
 terraform apply
 ```
 
-### Comparison
-
-Render bootkube assets directly with bootkube v0.4.2.
-
-#### On-host etcd
-
-```sh
-bootkube render --asset-dir=assets --api-servers=https://node1.example.com:443 --api-server-alt-names=DNS=node1.example.com --etcd-servers=http://127.0.0.1:2379
-```
-
-Compare assets. The only diffs you should see are TLS credentials.
-
-```sh
-diff -rw assets /home/core/cluster/mycluster
-```
-
-#### Self-hosted etcd
-
-```sh
-bootkube render --asset-dir=assets --api-servers=https://node1.example.com:443 --api-server-alt-names=DNS=node1.example.com --experimental-self-hosted-etcd
-```
-
-Compare assets. Note that experimental must be generated to a separate directory for terraform applies to sync. Move the experimental `bootstrap-manifests` and `manifests` files during deployment.
-
-```sh
-diff -rw assets /home/core/cluster/mycluster
-```
+Find bootstrap assets rendered to the `asset_dir` path. That's it.

-# NOTE: Across this module, the following syntax is used at various places:

-#
-# Due to https://github.com/hashicorp/hil/issues/50, both sides of conditions
-# are evaluated, until one of them is discarded. Unfortunately, the
-# `{tls_private_key/tls_self_signed_cert}.kube-ca` resources are created
-# conditionally and might not be present - in which case an error is
-# generated. Because a `count` is used on these ressources, the resources can be
-# referenced as lists with the `.*` notation, and arrays are allowed to be
-# empty. The `join()` interpolation function is then used to cast them back to
-# a string. Since `count` can only be 0 or 1, the returned value is either empty
-# (and discarded anyways) or the desired value.
