Digitalocean Terraform Microk8s

Bootstrap a multi node Microk8s in digitalocean with Terraform.

For example to bootstrap 1 controller and 1 worker.

module "microk8s" {
    source = "git::https://github.com/balchua/do-microk8s"
    worker_node_count = "1"
    os_image = "ubuntu-18-04-x64"
    controller_size = "s-4vcpu-8gb"
    region = "sgp1"
    worker_size = "s-4vcpu-8gb"
    digitalocean_ssh_fingerprint = "${var.digitalocean_ssh_fingerprint}"
    digitalocean_private_key = "${var.digitalocean_private_key}"
    digitalocean_token = "${var.digitalocean_token}"
    digitalocean_pub_key = "${var.digitalocean_pub_key}"
}

Digitalocean TF environment variables

You must have these environment variables present.

TF_VAR_digitalocean_token=<your DO access token>
TF_VAR_digitalocean_ssh_fingerprint=<Your private key fingerprint>
TF_VAR_digitalocean_private_key=<location of your private key>
TF_VAR_digitalocean_pub_key=<location of your public key>

Creating the cluster

Simply run the terraform plan and then terraform apply

Once terraform completes, you should be able to see the cluster.

Login to the master node using ssh root@masterip, then issue the command below.

root@microk8s-controller-cetacean:~# microk8s.kubectl get no
