DESCRIPTION
gcrane-help outputs comprehensive usage information for the gcrane CLI, a lightweight tool for interacting with Google Container Registry (GCR) and OCI-compatible registries. It lists the command synopsis, available subcommands (e.g., ls, cp, pull, push), global flags, and exit codes.
Without arguments, it shows general help. With a subcommand, like gcrane-help ls, it details that subcommand's syntax, options, and examples. gcrane supports tasks like listing repositories, copying images across registries, inspecting manifests/layers, tagging, digest computation, and auth management via Docker config.
Ideal for developers and ops teams automating container workflows. It handles multi-platform images and insecure connections for local testing. Note: Inherits Docker auth for seamless GCR access.
CAVEATS
gcrane is unmaintained; migrate to crane. Install requires Go; no package managers.
