GitHub Container Registry (GHCR)
GitHub Container Registry is GitHub's container image registry, commonly used to publish OCI images next to the source repositories that build them.
GitHub Container Registry (GHCR) stores OCI container images under GitHub namespaces. A project can build an image with GitHub Actions, publish it to GHCR, and keep the source code, packages, and permissions in one place.
Images are usually named under ghcr.io, for example ghcr.io/owner/project:tag.
The permission model is the part to check. Packages can inherit repository permissions, but they do not always behave the way people expect after a repository moves or visibility changes. Test pulls from the account or cluster that will use the image; your own laptop is not enough proof.
