Configure Service Principal Authentication for Azure Container Registry

Azure Container Registry provides the functionality to store and share private container images. Within this hands-on lab, we’ll review the permissions for a service principal to access Azure Container Registry. This is helpful in scenarios where you have apps/scripts that need some form of automated access to push/pull images to/from your registry. We'll push and pull some images from the registry and run a container image.

    3. Pull the ASP.NET sample container image from Microsoft's public repository using docker pull .
    4. Tag the image with your repository using docker tag <REGISTRY_LOGIN_SERVER>/aspnetapp.
    5. Push the image to your repository using docker push <REGISTRY_LOGIN_SERVER>/aspnetapp.
    6. Retreive the local Microsoft image ID with docker image ls .
    7. Remove the Microsoft image by running docker image rm <IMAGE_ID> -f.
    8. Pull the image from your repository with docker pull <REGISTRY_LOGIN_SERVER>/aspnetapp.
    9. Run the image with docker run -p 8080:8080 -d <REGISTRY_LOGIN_SERVER>/aspnetapp:latest.
