Problem:
When creating a container remote, I’ve noticed that the upstream-name is a required argument to specify the image needed to synchronize. I would like to know if there is a way to synchronize all the images of a repository subfolder, instead of creating a remote for each image individually ?
Pulpcore version:
pulp_core: 3.69.0
pulp_container: 2.22.0
Thank you.
Currently no. Right now you have to individually create a new remote for each image you want to sync. Part of this is because the Docker V2 API doesn’t have an easy endpoint for listing out all the available images in the registry or a specific namespace. Some registries do implement a catalogue endpoint (Registry catalog - Pulp Project), but it isn’t standard so we don’t use it for our syncs.
The next best option we have is pull-through caching (Configure Pull-Through Caching - Pulp Project). With this you can specify an upstream registry as a source of truth and then Pulp will proxy the request and then save the image locally for future use. It even has filtering abilities to limit what Pulp is allow to pull.
Thank you for the reply, I will try to setup pull-through caching.
