go-containerregistry

Defines interfaces like Image and Layer as immutable views, ensuring thread-safe and consistent operations, which is central to the library's philosophy for reliable container tooling.

Supports multiple backends including remote registries, tarballs, Docker daemons, and OCI layouts, as listed in the README under v1.Image sources and sinks, enabling flexible image handling.

The mutate package allows creating new immutable images after changes, facilitating efficient transformations without side effects, which is optimized for common tooling patterns.

Includes crane, gcrane, and krane for common registry interactions, reducing development effort for standard tasks like image copying and Kubernetes-aware authentication.
