Azure Kubernetes Service CI/CD Demo

Overview

This repo demonstrates how to deploy networking infrastructure, Azure Kubernetes Service (AKS) clusters and the Azure voting app across 3 environments, dev, test & prod.

Two GitHub action workflows deploy the solution:

  • Infrastructure (Networking, Monitoring, AKS clusters, etc.)
    • .github/workflows/infrastructure.yml
  • Workload (Azure Voting app)
    • .github/workflows/workload.yml

Pre-requisites

  • Bash shell
  • kubectl CLI
  • Github account
    • Clone fork this repo to your github account, then clone it locally
    • Create a Federated credential between your GitHub account & Azure subscription
      • The script ./iac/setup-federated-identity.sh demonstrates how configure this
      • Alternatively, instructions can be found here

Deployment

  • Run the Infrastructure workflow
    • Either:
      • Make a change to the repo, commit & push the changes (git add ., git commit, git push)
    • Or:
      • Run the .github/workflows/infrastructure.yml workflow from the GitHub Actions tab in the GitHub portal.

Testing

  • Only the production environment is exposed via an Azure Load Balancer
    • Get the production cluster's kubeconfig file
      • $ az aks get-credentials -n '<your cluster name>' -g 'demo-workload-prod-rg' --admin
    • Using the bash shell, get the public IP assigned to the 'azure-vote-front' service in the 'azure-vote' namespace
      • $ EXTERNAL_IP=$(kubectl get svc azure-vote-front -n azure-vote --output jsonpath='{.status.loadBalancer.ingress[0].ip}')
    • Hit the endpoint using curl (or type 'http://<EXTERNAL_IP>' in a browser
      • $ curl http://$EXTERNAL_IP
