# ✅ Update the values to be used to backend configuration.
# ⚠️ This is pre-requisite to execute the code.
# ❌ If the below resources are not present in the Azure Cloud, the terraform code will ❌ FAIL.

resource_group_name  = <ENTER backend - Resource Group>          # Example: "rg-backend"
storage_account_name = <ENTER backend - Storage Account>         # Example: "storageaccount"
container_name       = <ENTER backend - Storage Container Name>  # Example: "storagecontainer"
key                  = <ENTER backend - State File Name>         # Example: "a.terraform.tfstate"

Step 02 - Update azure subscription id in the below mentioned file.

✅ Update this with your own subscription ID.

📝 infra01.auto.tfvars

---------------------------------------------------------------------------------------------------
# ✅ Update this variable with your own subscription ID.
main_provider_subscription_id = "00000000-0000-0000-000000000000"

Step 03 - Following command needs to be executed to initialize the backend.

💡 Run with -backend-config parameter, else the initialize will ask for user input.

terraform init -backend-config='backend-config-infra01.hcl'
OR
terraform init -backend-config='backend-config-infra01.hcl' -upgrade

Step 04 - Following commands can be used to proceed with infrastructure creation.

terraform validate
terraform plan

Step 05 - - Following commands can be used to proceed with infrastructure creation.

terraform apply

Output

📤 Output values displayed to user after successful execution of the code.

Apply complete! Resources: 9 added, 0 changed, 0 destroyed.

Outputs:

root_output_child_kubernetes_cluster = "K8s Cluster Name: aks1-xxxxxxxxxx"          # ☸️ Kubernetes Cluster Name 
root_output_resource_group_name      = "Resource Group Name: rg-aks1-xxxxxxxxxx"    # 📦 Resource Group Name

Next Steps

📤 Open Powershell CLI and execute the following command to merge the K8s cluster in your config file.

Users can use the kubectl commands in their CLI.

az aks get-credentials --name "aks1-xxxxxxxxxx" --resource-group "rg-aks1-xxxxxxxxxx" --overwrite-existing
