Azure DevOps Pipeline: Build and Deploy Azure Container App

In this post, let's see how we can build and deploy an Azure Container App from an Azure DevOps Pipeline.

Here for deployment, I am using az containerapp update.

trigger:
  branches:
    include:
      - main
 
pool:
  vmImage: ubuntu-latest
 
variables:
  acrServiceConnection: <ACR_SERVICE_CONNECTION>
  acrName: myacr.azurecr.io
  imageRepositoryName: '<ACR_REPOSITORY_NAME>'
  containerAppServiceConnection: '<CONTAINER_APP_SERVICE_CONNECTION>'
  containerAppResourceGroup: '<CONTAINER_APP_RESOURCE_GROUP>'
  containerAppName: '<CONTAINER_APP_NAME>'
 
name: $(Build.BuildId)
 
stages:
- stage: Build
  displayName: Build
  jobs:  
  - job: Build
    displayName: Build Docker Image
    steps:
    - task: Docker@2
      displayName: Build and push an image to container registry
      inputs:
        containerRegistry: '$(acrServiceConnection)'
        repository: '$(imageRepositoryName)'
        command: 'buildAndPush'
        Dockerfile: '**/Dockerfile'
        buildContext: './'
        tags: '$(Build.BuildId)'
 
- stage: Deploy
  displayName: Deploy
  dependsOn:
  - Build
  condition: succeeded('Build')
  jobs:  
  - deployment: Deployment
    displayName: Deploy to Container App
    # Requires an environment named 'Development'
    environment: Development
    strategy:
      runOnce:
        deploy:
          steps:
           - task: AzureCLI@2
             displayName: Update Container App
             inputs:
               azureSubscription: '$(containerAppServiceConnection)'
               scriptType: 'bash'
               scriptLocation: 'inlineScript'
               inlineScript: |
                 az containerapp update \
                 --name $(containerAppName) \
                 --resource-group $(containerAppResourceGroup) \
                 --image '$(acrName)/$(imageRepositoryName):$(Build.BuildId)' \
                 --set-env-vars \
                   'MongoDB__ConnectionString=<VALUE>' \
                   'ServiceBus__ConnectionString=<VALUE>' \
                 --min-replicas 1 \
                 --max-replicas 1

Azure DevOps already has an Azure Container Apps Deployment Task AzureContainerApps@1, which I haven't used, but do check it out.

Hope this helps.

Happy Coding.
