Just playing around with AKS and Terraform

Preparation

Create a service principal to interact with your Azure subscription. You can have instructions here

Set the environment variables, in this way terraform will be able to automatically use them when initializing and you don't have to declare them in the provider's configuration.

$ export ARM_CLIENT_ID="00000000-0000-0000-0000-000000000000"
$ export ARM_CLIENT_SECRET="00000000-0000-0000-0000-000000000000"
$ export ARM_SUBSCRIPTION_ID="00000000-0000-0000-0000-000000000000"
$ export ARM_TENANT_ID="00000000-0000-0000-0000-000000000000"

Make sure you also have az cli installed on your system. You may also need to perform az login.

Building the infra

Take a look at variables.tf file and configure as you wish.

Once ready, apply the usual workflow for terraform:

terraform init
terraform plan
terraform apply

Connecting to the created AKS cluster

After the cluster is provisioned, a kubeconfig file is created under your home directory:

resource "local_file" "kubeconfig" {
  depends_on   = [azurerm_kubernetes_cluster.faks_k8s_cluster]
  filename     = pathexpand("~/.kube/${azurerm_kubernetes_cluster.faks_k8s_cluster.name}-config.yaml")
  content      = azurerm_kubernetes_cluster.faks_k8s_cluster.kube_config_raw
}

You can use it to access the cluster with kubectl.
