Quay.io container registry

Quay.io is a service that provides a container registry for storing and distributing container images^[400-devops-03-containerization-query-io.md].

Usage

To interact with the registry, users must authenticate via the Docker CLI using docker login quay.io^[400-devops-03-containerization-query-io.md]. After making changes to a container, such as creating a new file in a busybox instance, the updated state can be saved to a new image using docker commit^[400-devops-03-containerization-query-io.md].

The committed image is then pushed to the Quay.io repository using the docker push command^[400-devops-03-containerization-query-io.md]. Upon a successful push, the service returns a digest (e.g., SHA256) and size for the image^[400-devops-03-containerization-query-io.md].
