How to sync images with digest using tag in pulp container

Development
#1

I want to sync images with digest tag in pulp container registry.
ex-

gcr.io/knative-releases/knative.dev/serving/cmd/controller@sha256:b11dbcba050eac9084edd021b7e0eee16b39c9e397b245bc4227266af1893404

For tagged images, I can successfully use the --include-tag or --exclude-tag filter options to filter specific tags.
However, the same approach does not work for SHA256 digests.
if I put:
--include-tags["sha256-b11dbcba050eac9084edd021b7e0eee16b39c9e397b245bc4227266af1893404"]

The sync operation completes successfully but does not filter the specified image.
when trying to sync without providing filter option --include-tags then it works out fine.

Raised issue on Pulp container: As a user I should be able to sync only images with digest · Issue #1909 · pulp/pulp_container

Is there any workaround on this issue?

#2

No, currently we only support the tag name for filtering. We plan to add support for digest filtering too.

#3

Yes, this is filed upstream at https://github.com/pulp/pulp_container/issues/1563

And actually https://github.com/pulp/pulp_container/issues/1909 too, we need to consolidate those two.
