bootkube-terraform

bootkube-terraform is a Terraform module that renders bootkube assets, just like running the binary bootkube render. It aims to provide the same variable names, defaults, features, and outputs.

Status

Usage

Use the bootkube-terraform module within your existing Terraform configs. See the input variables.tf of example terraform.tfvars.example.

module "bootkube" {
  source = "git://https://github.com/dghubble/bootkube-terraform.git"

  cluster_name = "example"
  api_servers = ["node1.example.com"]
  etcd_servers = ["http://127.0.0.1:2379"]
  output_path = "/home/core/clusters/mycluster"
}

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.

terraform get
terraform plan
terraform apply

Comparison

Render bootkube assets directly with bootkube v0.4.2.

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.

diff -rw assets /home/core/cluster/mycluster
