Intro

A registry of Docker and Open Container Initiative (OCI) images, with support for all OCI artifacts

Documentation

Like Docker Hub, Container Registry is organized around repositories that contain one or more images
You can sign images to increase trust and reduce the chances of an image becoming accidentally (or intentionally) corrupted or otherwise infected.
Before you can push an image to your registry, you must tag it with the fully qualified name of your registry login server.
The login server name is in the format <registry-name>.azurecr.io (must be all lowercase)
docker tag mcr.microsoft.com/hello-world mycontainerregistry.azurecr.io/hello-world:v1 docker push <login-server>/hello-world:v1
In addition to storing and hosting images, you can also use Container Registry to build images.
Instead of building an image yourself and pushing it to Container Registry, use the CLI to upload the Docker file and other files that make up your image.

Tier	Description

Tier	Description
Basic	A cost-optimized entry point for developers learning about Azure Container Registry. Basic registries have the same programmatic capabilities as Standard and Premium (such as Azure Active Directory authentication integration, image deletion, and webhooks). However, the included storage and image throughput are most appropriate for lower usage scenarios.
Standard	Standard registries offer the same capabilities as Basic, with increased included storage and image throughput. Standard registries should satisfy the needs of most production scenarios.
Premium	Premium registries provide the highest amount of included storage and concurrent operations, enabling high-volume scenarios. In addition to higher image throughput, Premium adds features such as geo-replication for managing a single registry across multiple regions, content trust for image tag signing, private link with private endpoints to restrict access to the registry.

The following aspects of the image are defined:

The ENTRYPOINT in the file indicates which process will execute once we run a container from an image.

Run the az acr build command, which builds the image and, after the image is successfully built, pushes it to your registry

az acr build --image sample/hello-world:v1  \
    --registry <myContainerRegistry> \
    --file Dockerfile .

Use the az acr repository list command to list the repositories in your registry.

az acr repository list --name <myContainerRegistry> --output table
