Receiving Webhooks from the GitHub Container Registry

Webhooks cannot be registered directly on a GHCR image repository. Instead, package events are delivered from an associated source code repository as if the event precipitating the delivery had occurred there.

Refer to documentation for the GitHub Webhooks Receiver for further instructions.

note

If your GHCR image repository has not yet been associated with a source code repository, refer to these instructions.

note

GitHub can deliver webhooks only for events occurring in a container image repository associated with a source code repository.

This is a limitation of GitHub/GHCR and not a limitation of Kargo.
