Using Buildah with container registries
Prerequisite: Buildah version 0.9 or greater.
First some terminology. In the container image space, Docker popularized two terms:
- Container image registry
- Container image repository
The container image registry, or registry, is a shared data store for pushing and pulling container images. It has a well-known API for such requests. Docker Hub is an example of a public registry. Various vendors and developers store their images on Docker Hub. Most organizations I’ve dealt with don’t wish to pull images from a public registry for reasons such as security or network bandwidth usage. Instead they would prefer to use a local private registry.
