Setup CD on Azure Kubernetes Service (AKS) with Azure DevOps, Docker Compose and Helm

• Prerequisites
• Setup Build Pipelines (CI)
• Setup Release Pipelines (CD)
• What I learned

1. New release pipeline

   

2. Choose artifact as release source

   In some scenarios, new docker image from ACR or Docker Hub can be set as “Source type” to trigger the release.

   

3. Select Helm Chart template to deploy to Kubernetes

   

4. Setup release tasks

   

   • Authorize to Azure, Resource Group and AKS

     

   • Install Helm - keep the default settings

     

   • Helm Init - tick “Upgrade Tiller”

     

     Tiller is a service running at Kubernetes cluster to manage helm charts.

     Note: Arguments is empty, it will install both client and tiller.

     

   • Helm Upgrade - install helm charts in Kubernetes

     

     Select tgz package from artifact, regex can be used e.g. helm-*.tgz

     Value File can be used to replace configuration for specific environment e.g. values.Staging.yaml or values.Production.yaml

     Command will be generated like:

       helm upgrade --install --reset-values --values /helm/values.Production.yaml --wait azuredevops /helm-0.1.0.tgz
