# Set the variables
$ LOCATION="<location>";RG_NAME="<name>";STORAGE_ACCOUNT="<name>";CONTAINER_NAME="<name>";
# Create new resource group
$ az group create --location "$LOCATION" --name "$RG_NAME"
# Create new storage account
$ az storage account create --name "$STORAGE_ACCOUNT" --resource-group "$RG_NAME" --location "$LOCATION" --sku Standard_LRS
$ az storage container create --name "$CONTAINER_NAME" --account-name "$STORAGE_ACCOUNT"Now cp remote_state.tf.example remote_state.tf and fill the details:
terraform {
backend "azurerm" {
resource_group_name = "" # The value of $RG_NAME
storage_account_name = "" # The value of $STORAGE_ACCOUNT
container_name = "" # The value of $CONTAINER_NAME
key = "interview.terraform.tfstate" # You can left this unchanged
}
}Initialize Terraform - terraform init
Perform dry-run to check what will be deployed - terraform plan
Deploy - terraform apply
Check the resources once the deployment complete:
az aks list -o table
