terraform-render-bootstrap is a Terraform module that renders TLS certificates, static pods, and manifests for bootstrapping a Kubernetes cluster.

terraform-render-bootstrap is a low-level component of the 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.

Use the module to declare bootstrap assets. Check variables.tf for options and terraform.tfvars.example for examples.

module "bootstrap" {
  source = "git::https://github.com/poseidon/terraform-render-bootstrap.git?ref=SHA"

  cluster_name = "example"
  api_servers = ["node1.example.com"]
  etcd_servers = ["node1.example.com"]
}

Generate assets in Terraform state.

terraform init
terraform plan
terraform apply

To inspect and write assets locally (e.g. debugging) use the assets_dist Terraform output.

resource local_file "assets" {
  for_each = module.bootstrap.assets_dist
  filename = "some-assets/${each.key}"
  content = each.value
}
