I am trying to pull container images from registry.redhat.io and i’m getting this error when using nexus repo manager. I am using podman for this. Here is the error: DEBU[0001] Error pulling candidate nexus01.example.com:9093/rhel9/nginx-120:latest: internal error: unable to copy from source dock…

[image] Andrew Meyer: unauthorized: access to the requested resource is not authorized You have some sort of authentication error. Either between the client and Nexus, or Nexus and the remote registry.

I have anonymous access turned on…and this is trying to access redhat container registry.

Also if I look at the datastore for the repo, I see the container browsing the web ui. Is there any special trick to make this work with redhat’s container registry let alone yum/dnf repos?

I got this resolved. It was an auth issue on the nexus to repo side.

ok, so I tried switching this up and using a service account from redhat, but it looks like i’m having an auth issue again. Can you verify? DEBU[0000] Accessing "nexus.example.com:9093/rhel9/cups:latest" failed: reading manifest latest in nexus.example.com:9093/rhel9/cups: manifest unknown DEBU[0…

There is an outbound request log which you can examine for requests made by nexus to remotes.
