The Oracle Container Registry contains Docker images for licensed commercial Oracle software products that you may use in your enterprise. I then repeated this process for the rest of my images, you can find the full repo at https://github.com/russmckendrick/docker/ with the workflow files at https://github.com/russmckendrick/docker/tree/master/.github/workflows and finally, the resulting images are at https://github.com/russmckendrick?tab=packages. docker login myregistry.azurecr.io When using az acr login with an Azure Active Directory identity, first sign into the Azure CLI, and then specify the Azure resource name of the registry. In the next step I am getting the current date and time, then setting it as an output variable so I can use it on step #5: - name: Get current date id: date run: echo "::set-output name=date::$(date +'%Y%m%d%H%M')". This credential helper will help maintaining your credentials. Using az acr login with Azure identities provides Azure role-based access control (Azure RBAC). Now that the Dockerfile has been updated I needed to create a GitHub Action to build and push my images whenever the Dockerfile was updated, however, as the repo contains all of my Dockerfiles in separate folders I would need to ensure that I didn’t build and push every image each time that the repo was updated. Login to your Azure Container Registry: docker login azureadventcalendar.azurecr.io. It's strongly advised to migrate to GitHub Container Registry instead.

Now we are at the point where we are ready to login to the GitHub Container Registry service: - name: Login to the GitHub Container Registry uses: docker/login-action@v1 with: registry: ghcr.io username: ${{ github.repository_owner }} password: ${{ secrets.GHCR_TOKEN }}. Before pushing your docker image to the Azure Container Registry is important to apply a tag to your Docker container image. Container Registry is a single place for your team to manage Docker images, perform vulnerability analysis, and decide who can access what with fine-grained access control. If your token expires, you can refresh it by using the az acr login command again to reauthenticate. **' - 'ab/**'. az acr login uses the Docker client to set an Azure Active Directory token in the docker.config file. ** tells the workflow to ignore all changes to everything apart from the include folder which is defined as ab/**, unfortunately I can't use the ${{ github.workflow }} here as at this point in the workflow the it hasn't been started so I can use variables meaning I have to hardcode the path. For details on how to create a PAT click here and for more encrypted secrets see here. As you can see, the resulting output is a docker login command that you can use to authenticate your Docker client to your ECR registry. This section defines when the workflow should be triggered, here I am doing it whenever the main branch is pushed to — but only if any of the files in the ab folder changes. Now we are at the point where we are ready to login to the GitHub Container Registry service: - name: Login to the GitHub Container Registry uses: docker/login-action@v1 with: registry… Here is an example of how to build a Node.js application as a Docker file. “Docker Buildx” you might be thinking to yourself, what's that?

I did actually suspect that, but my reference to the Container Registry (azureContainerRegistry) in the 2nd and 3rd task action for build and push does not work as expected. **' - 'ab/**' jobs: login-build-and-push: runs-on: ubuntu-latest steps: - name: Checkout uses: actions/checkout@v2 - name: Set up Docker Buildx uses: docker/setup-buildx-action@v1 with: driver-opts: image=moby/buildkit:master - name: Get current date id: date run: echo "::set-output name=date::$(date +'%Y%m%d%H%M')" - name: Login to the GitHub Container Registry uses: docker/login-action@v1 with: registry: ghcr.io username: ${{ github.repository_owner }} password: ${{ secrets.GHCR_TOKEN }} - name: Build and push image id: docker_build uses: docker/build-push-action@v2 with: push: true context: ./${{ github.workflow }}/ file: ./${{ github.workflow }}/Dockerfile tags: | ghcr.io/${{ github.repository_owner }}/${{ github.workflow }}:latest ghcr.io/${{ github.repository_owner }}/${{ github.workflow }}:${{ steps.date.outputs.date }} - name: Image digest run: echo ${{ steps.docker_build.outputs.digest }}. This is the natural evolution of how container images are handled in GitHub Packages as you can now publish public images for free. The Azure Container Registry Admin Account and Service Principals. See linked content for details. ... $ docker login myregistrydomain.com:5000 Provide the username and password from the first step. Output displays the access token, abbreviated here: Then, run docker login, passing 00000000-0000-0000-0000-000000000000 as the username and using the access token as password: If you assign a service principal to your registry, your application or service can use it for headless authentication. Easy access to Oracle products for use in Docker containers.
