How to use only push side

Hi all,

I already use jib maven plugin to build the docker image then I’m trying to use only the push part but it seems is trying to also build the image.

Does anyone know if is that possible to achieve? I have tried in different ways with custom builder and context path but getting same error, following yml configuration.

https://github.com/rodrigorodrigues/microservices-design-patterns/blob/master/.github/workflows/docker-build-push-image-authentication-service.yml

context: .

  - name: Set up Docker Buildx
    uses: docker/setup-buildx-action@v1

  # Build the Docker image with Maven
  - name: Build
    run: |
      mvn clean install -q -pl authentication-service -am -B -Dorg.slf4j.simpleLogger.log.org.apache.maven.cli.transfer.Slf4jMavenTransferListener=warn -Dspring.profiles.active=travis jib:dockerBuild
  # Login to Dockerhub
  - name: Login to DockerHub
    uses: docker/login-action@v1
    with:
      username: ${{ secrets.DOCKERHUB_USERNAME }}
      password: ${{ secrets.DOCKERHUB_TOKEN }}

  # Push the Docker image
  - name: Push
    id: docker_build
    uses: docker/build-push-action@v2
    with:
      context: .
      push: true
      tags: fielcapao/microservices-design-patterns:authentication-service

custom builder

  - name: Set up Docker Buildx
    uses: docker/setup-buildx-action@v1
    id: buildx
    with:
      install: false

  # Build the Docker image with Maven
  - name: Build
    run: |
      mvn clean install -pl authentication-service -am -B -Dspring.profiles.active=travis jib:dockerBuild
  # Login to Dockerhub
  - name: Login to DockerHub
    uses: docker/login-action@v1
    with:
      username: ${{ secrets.DOCKERHUB_USERNAME }}
      password: ${{ secrets.DOCKERHUB_TOKEN }}

  # Push the Docker image
  - name: Push
    id: docker_build
    uses: docker/build-push-action@v2
    with:
      builder: ${{ steps.buildx.outputs.name }}
      push: true
      tags: fielcapao/microservices-design-patterns:authentication-service

I’m trying to use only the push part but it seems is trying to also build the image.

That’s not the purpose of this action but you can use docker push in a shell step:

  - name: Build
    run: |
      mvn clean install -q -pl authentication-service -am -B -Dorg.slf4j.simpleLogger.log.org.apache.maven.cli.transfer.Slf4jMavenTransferListener=warn -Dspring.profiles.active=travis jib:dockerBuild
  - name: Login to DockerHub
    uses: docker/login-action@v1
    with:
      username: ${{ secrets.DOCKERHUB_USERNAME }}
      password: ${{ secrets.DOCKERHUB_TOKEN }}
  - name: Push
    run: |
      docker push fielcapao/microservices-design-patterns:authentication-service

But looking at your maven logs, I don’t see anything related to a “docker build”.

@akhilerm Yes you can push multi platform images with this action, see https://github.com/docker/build-push-action#multi-platform-image.

(Need to push to dockerhub, quay etc).

To push to multi registries, see https://github.com/docker/build-push-action#push-to-multi-registries
