About

Github action to retag and push multiplatform images to multiple registries

💡 See also:

• login action
• docker-meta action

The v1 version of this action heavily relied on work done by @tonistiigi.

The current version uses crane from google for copying images, and the action itself is a modified version of script written by @crazymax

Usage

Basic

name: Push-Image

on: push

jobs:
  push-image:
    runs-on: ubuntu-latest
    steps:

      - name: Login Quay
        uses: docker/login-action@v1
        with:
          registry: 'quay.io'
          username: ${{ secrets.QUAY_USERNAME }}
          password: ${{ secrets.QUAY_TOKEN }}

      - name: Login Dockerhub
        uses: docker/login-action@v1
        with:
          username: ${{ secrets.DOCKERHUB_USERNAME }}
          password: ${{ secrets.DOCKERHUB_TOKEN }}

      - name: Push image
        uses: akhilerm/tag-push-action@v2.0.0
        with:
          src: docker.io/akhilerm/node-disk-manager:ci
          dst: |
            quay.io/akhilerm/node-disk-manager-amd64:ci

1. Login to all the registries from which you want to pull and push the multiplatform image.

2. Specify the src and dst registry, both of which are mandatory fields. The action allows multiple destination registries specified as a yaml string.

NOTE: If dockerhub is used, make sure that docker.io is specified in the image name

Using with docker/metadata-action

The action can be used alongside metadata-action to generate tags easily.

name: Push-Image

on: push

jobs:
  push-image:
    runs-on: ubuntu-latest
    steps:

      - name: Login Dockerhub
        uses: docker/login-action@v1
        with:
          username: ${{ secrets.DOCKERHUB_USERNAME }}
          password: ${{ secrets.DOCKERHUB_TOKEN }}

      - name: Docker meta
        id: meta
        uses: docker/metadata-action@v3
        with:
          images: docker.io/akhilerm/node-disk-manager     

      - name: Push image
        uses: akhilerm/tag-push-action@v2.0.0
        with:
          src: docker.io/akhilerm/node-disk-manager:ci
          dst: |
            ${{ steps.meta.outputs.tags }}

The output tags from the meta step can be used as destination tags for this github action.

Use a custom docker config file

The standard docker config path on GitHub runner is /home/runner/.docker/config.json. In case you're running on a custom GitHub runner, and your config path is not standard, then the docker-config-path can be used.

  - name: Push image
    uses: akhilerm/tag-push-action@v2.0.0
    with:
      docker-config-path: /home/myuser/.docker/config.json
      src: docker.io/akhilerm/node-disk-manager:ci
      dst: |
        quay.io/akhilerm/node-disk-manager-amd64:ci
