Are Docker Images no longer published?

You can do:

docker pull rockylinux/rockylinux:8.10
docker pull rockylinux/rockylinux:9.5

So not sure what links you’ve been exploring on Docker Hub, but those tags above do exist. @neil would need to fix the library links for it be work in the shorthand way:

docker pull rockylinux:8.10

for example. Incidently, podman deals with this better.
