Examples with Terraform

Matchbox automates network booting and provisioning Container Linux clusters. These examples show how to use matchbox with Teraform to create official reference clusters.

Name Description
etcd3-install Install a 3-node etcd3 cluster
bootkube-install Install a 3-node self-hosted Kubernetes v1.6.2 cluster

Modules

Matchbox also provides Terraform modules you can use directly within your own Terraform configs. Modules are updated regularly so it is recommended that you pin the module version (e.g. ref=sha) to keep your configs deterministic.

module "profiles" {
  source = "git::https://github.com/coreos/matchbox.git//examples/terraform/modules/profiles?ref=4451425db8f230012c36de6e6628c72aa34e1c10"
  matchbox_http_endpoint = "${var.matchbox_http_endpoint}"
  container_linux_version = "${var.container_linux_version}"
  container_linux_channel = "${var.container_linux_channel}"
}
