How to combine with image push/release?

[hazcod]

Hi, I have a single repo containing my container source and the relevant helm package. I'd like to do the following on every push to master:

• calculate new semantic release version
• build & push image to github registry
• update a helm repository with my chart on branch gh-pages

Altough I'm unsure how to do this since chart-releaser will create the GitHub release itself, but there is no way to re-use that release for the image tag? Anyone doing the same?

Hi @hazcod, I have a similar workflow. I use Chart.yaml version to version everything (docker, git tag, chart etc.), this way if someone wants to update version it goes through pull request (I don't think semver can be calculated, but has to be created manually). I also use my own version of chart releaser -> https://github.com/pete911/hcr

Github action looks like this (you need to replace <project-name> and <user>, also instead of dockerhub you want to use ghcr, but the rest should be the same):

name: release

on:
  push:
    branches:
      - main
    paths:
      - "charts/<project-name>/Chart.yaml"

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          fetch-depth: 0

      - name: Get helm chart version
        run: echo "CHART_VERSION=$(grep '^version:' charts/<project-name>/Chart.yaml | cut -d ":" -f2 | tr -d ' ')" >> $GITHUB_ENV

      - name: Create tag
        uses: actions/github-script@v3
        with:
          github-token: ${{ github.token }}
          script: |
            github.git.createRef({
              owner: context.repo.owner,
              repo: context.repo.repo,
              ref: "refs/tags/${{ env.CHART_VERSION }}",
              sha: context.sha
            })

      - name: Set up qemu
        uses: docker/setup-qemu-action@v1

      - name: Set up docker buildx

      - name: Build and push docker image
        uses: docker/build-push-action@v2
        with:
          context: .
          platforms: linux/amd64,linux/arm64
          push: true

          tar -xzf hcr.tar.gz
          rm -f hcr.tar.gz

        run: |
          git config user.email "[email protected]"
