I can't use the image that the documentation provides when I tried to copy the required images to my private registry. Here's the error message:

time="2025-06-22T18:45:01Z" level=fatal msg="initializing source docker://eqalpha/keydb:6.3.3: reading manifest 6.3.3 in docker.io/eqalpha/keydb: manifest unknown"
Error: Coping eqalpha/keydb:6.3.3 jerryhan3/keydb:6.3.3 failed

Then I searched on keydb's docker hub page, and found out that they have changed their tag names: they added the CPU architecture name to the tag name, which caused the original tag name no longer available.

Now they use alpine_x86_64_v6.3.3, x86_64_v6.3.3, and arm64_v6.3.3 as their tag names. Maybe the docker-compose.yml files on self-hosting page should be updated to these new tags too.
