How to login to Docker registries using Github Actions

The actions/docker action has now been deprecated. If you visit the repository you will see that the repository is archived and has the following message.

This action is deprecated in favor of using the run script step in the new YAML language to run the docker cli.

https://github.com/actions/docker

So the recommended way to login to Docker registries is to use the run script command as follows.

For the public DockerHub registry:

name: my workflowon:  push:    branches:      - masterjobs:  build:    runs-on: ubuntu-latest    steps:      - uses: actions/checkout@v1      - name: Login to DockerHub Registry        run: echo ${{ secrets.DOCKERHUB_PASSWORD }} | docker login -u ${{ secrets.DOCKERHUB_USERNAME }} --password-stdin

For a private registry, such as the new GitHub Package Registry, you also need to specify the hostname:

name: my workflowon:  push:    branches:      - masterjobs:  build:    runs-on: ubuntu-latest    steps:      - uses: actions/checkout@v1      - name: Login to GitHub Package Registry        run: echo "${{ secrets.DOCKER_PASSWORD }}" | docker login docker.pkg.github.com -u "${{ secrets.DOCKER_USERNAME }}" --password-stdin

Also see this answer for complete workflow examples of docker image publishing.

Try this action instead as actions/docker/login@master appears to have been deprecated.

I found Git hub action: Build and push Docker images

https://github.com/marketplace/actions/build-and-push-docker-images

It works well, I was able to build and push docker image to Docker Hub.
