CodePipeline

Links: 102 AWS DVA Index
Keywords: Manual approval, orchestration

  • Visual Workflow to orchestrate your CICD

  • Sources:

    • CodeCommit
    • ECR
    • S3
    • GitHub

  • Build: CodeBuild, Jenkins, CloudBees, TeamCity

  • Test: CodeBuild, AWS Device Farm, 3rd party tools

  • Deploy: CodeDeploy, Elastic Beanstalk, CloudFormation, ECS, S3,

  • Consists of stages:

    • Each stage can have multiple sequential actions and/or parallel actions
    • Example stages: Build (CodeBuild) → Test (CodeBuild) → Deploy (CodeDeploy) → Load → Testing
  • Manual approval action can be defined at any stage.
  • If any of the stages fail before deploying the code then it won't deploy the code. Like if some tests fail in CodeBuild.
Stages can have multiple action groups.

Here + Add Action on the right hand side is for parallel actions.

Artifacts

  • Each pipeline stage can create artifacts
  • Artifacts stored in an S3 bucket and passed on to the next stage

Troubleshooting

  • For CodePipeline Pipeline/Action/Stage Execution State Changes we can use CloudWatch Events (Amazon EventBridge). Example:
    • You can create events for failed pipelines
    • You can create events for cancelled stages
A company has implemented AWS CodePipeline to automate its release pipelines. The Development team is writing an AWS Lambda function that will send notifications for state changes of each of the actions in the stages.

Create an Amazon CloudWatch Events (EventBridge) rule that uses CodePipeline as an event source.

  • If CodePipeline fails a stage, your pipeline stops, and you can get information in the console
  • If pipeline can't perform an action, make sure the IAM Service Role attached does have enough lAM permissions (IAM Policy)
  • AWS CloudTrail can be used to audit AWS API calls
You can't use SNS for getting notifications on failures.
