Registries, repositories, and images
In the previous steps, we managed to deploy our own instance of ACR. What we have currently is a private registry that will allow us to push container images for later use. In this section, we will cover two additional topics – repositories and images. Let's briefly describe them:
- A registry is an instance of ACR. It is the main layer of the service, which acts as a control plane and gives us the possibility to configure things such as encryption, identity, and networking.
- A repository is a logical container for your images. Each registry can have multiple repositories. You can think of them as categories of images or projects – once a repository is created, you can start pushing your images there.
- An image is a blueprint for each container. Images can be pulled onto a machine and then used to create an instance of it called a container. In ACR, images must be pushed into repositories.
