How can I push a git tag to GitHub in AWS Pipeline using a CodeStar Connection?

Question

I have an AWS Pipeline that is connected to GitHub via CodeStar Connection. The process looks like this:

1. Pull source from GitHub
2. Build project
3. Run tests
4. Deploy

Before (or as part of) step 4 I would like the AWS Pipeline to tag the code with a git tag and then push this back to the repo in GitHub.

How can I do this?

Answer 1

You will need a CodeBuild action before/after Step4 in the Pipeline that will basically execute the git tagging commands and push to origin as mentioned by other commenters. A sample buildspec for CodeBuild project will look like:

version: 0.2 

env:
  git-credential-helper: yes


phases: 
  install: 
    runtime-versions: 
      python: 3.7 

  build: 
    commands: 
      - echo Build started on `date`
      - git checkout master
      - git tag ${BUILD_NUMBER} ${CODEBUILD_RESOLVED_SOURCE_VERSION}
      - git push origin master --tags ${BUILD_NUMBER}
