Create an AKS Cluster and Deploy Applications

In this objective, you will create a Virtual Network (VNet) that will be used by the AKS cluster in a resource group provided by the lab. The VNet will have an address space of 10.64.0.0/16 and two subnets:

• ingress: "10.64.4.0/24"
• nodes: "10.64.0.0/22"

1. Login into the Azure CLI using the provided credentials.
2. Retrieve the resource group name from the lab.
3. Create a new Terraform configuration with the resource group as a data source.
4. Add the desired VNet using the VNet module.
5. Deploy the VNet using Terraform.

In this objective, you will create an AKS cluster using Terraform. The AKS cluster will be created in the resource group provided by the lab and will use the VNet created in the previous objective. The AKS cluster has the following requirements:

• Sku tier: Standard
• Kubernetes version: latest
• Upgrades: Automatic and Node Image OS
• Log analytics: Disabled
• System nodes: 2
• System node size: Standard_D2s_v3
• Network plugin: Azure CNI
• Network policy: Azure
• Load balancer: Standard
• Node pools: 1
• Node pool count: 1
• Node pool VM size: Standard_D2s_v3
• RBAC: enabled, no Entra ID/Azure AD integration

1. Add an AKS cluster to the existing configuration using the AKS module and the VNet provisioned in the previous objective.
2. Configure the arguments of the module to match the cluster requirements.
3. Add outputs for the following: cluster FQDN, client certificate, client key, and cluster CA certificate.
4. Deploy the AKS cluster and validate the deployment.

In this objective, you'll use the Helm provider to deploy Flux CD to the AKS cluster. The installation process can be found in this guide for the Flux provider.

1. Add the Helm provider to your configuration.
2. Configure the Helm providers with credentials from the AKS cluster.
3. Add a helm_release resource to deploy the flux2 chart to the AKS cluster.
4. Confirm that Flux CD has been installed successfully on the cluster.

In this objective, you will create a new Terraform configuration that deploys this sample application using Flux CD and the Kubernetes provider. Refer to the Flux CD documentation for manifest examples.

1. Create a new Terraform configuration using the Kubernetes provider.
2. Use the terraform_remote_state data source to access the outputs of the cluster deployment.
3. Configure the Kubernetes provider with the values from the terraform_remote_state data source.
4. Create kubernetes_manifest resources for the following:
   • Flux GitRepository - Use this repository: https://github.com/ned1313/taco-fleet
   • Flux Kustomization - Targeting the infrastructure directory of the repository
   • Flux Kustomization - Targeting the dotnet-lb directory of the repository
5. Deploy the manifests using Terraform.
6. Verify application deployment and access through the public IP address on the load balancer.
