While working on creating training material on Azure IaC using Terraform, I created a small demo project to create an Azure AKS cluster from scratch and integrated it with Terraform Cloud. It came out quite nicely and therefore I thought I would share it with larger audience 🙂.
Detailed instructions can be found on the repo README. You'll need your own Azure account and a subscription. The AKS cluster code is a local module and the created cluster will have the following features:
- Nodes with Ubuntu OS
- Azure CNI
- Separate vnet and subnet
- Single nodepool with autoscaling enabled
- AKS managed Azure AD integration
- System-assigned managed Identity
- Cluster auto-upgrade enabled
Quick note about Terraform Cloud - if you haven't tried it yet, you should. It has a free plan for smaller teams up to 5 and provides a way to manage state remotely and securely.
Happy coding 🤘.

terraform loginand follow the instructions. -
Create and configure an Azure service principal in TF Cloud workspace. This will allow TF workspace to connect to and create resources in the Azure subscription.
Add the necessary permissions to the SP to get the AKS admin group name from the
azureadprovider. We only needGroup.Read.Allpermission.
Examples
Each subdirectory represents one scenario and usually corresponds to one TF Cloud workspace.
