As reading GitHub Package billing (stated to be same for Container Registry in the future), Container Registry is said to be free for storage and transferring for public repositories.
Docker or (OCI) manifests are used to check if the image is still same, or just for querying meta information from the selected container. Will there be any rate-limits based on IP address for this, or this is also included the free statement? (amount of queries coming from same place)
Current workflow for getting manifest information requires getting token from
ghcr.io/auth which is further used for getting the manifest information.
Knowing, whether manifest queries are staying limitless (or high count) for anonymous users, is important factor for me that registry would be usable.
(Sidenote: I noticed that auth tokens are lasting for very long time (at least more than 24 hours), I’m not sure if this is intended. )
