Azure Release Pipelines/Deployments

• Sample dotnet application which we used for creating releases

---
pool:
  name: 'Azure Pipelines'
  vmImage: 'ubuntu-latest'

trigger:
  - master

stages:
  - stage: 'buildpackage'
    displayName: 'Build and Package'
    jobs:
      - job: 'buildpackage'
        displayName: 'Build and Package'
        steps:
          - task: DotNetCoreCLI@2
            inputs:
              command: publish
              publishWebProjects: True
              arguments: '--configuration Release --output $(Build.ArtifactStagingDirectory)'
              zipAfterPublish: True
          - task: PublishPipelineArtifact@1
            inputs:
              targetPath: '$(Build.ArtifactStagingDirectory)' 
              artifactName: 'qtwebapp'

• We will be taking a sample application and performing the following steps
  • build docker image
  • scan docker image
  • push docker image to docker registry
  • deploy the container as deployment into k8s cluster
• The Application we will be using
  • Git hub Refer Here
  • Refer Here
• Create Kubernetes Cluster Refer Here
• Setup service connection with Kubernetes Cluster and select namespace
  
• Refer Here for the basic pipeline to build docker image
• Refer Here for sample aks azure devops deployment pipeline
• Refer Here for changes in pipeline added to deploy to k8s cluster
• The yaml for deployment
