We are using Nexus v3.13 as Docker Registry and Docker Hub Proxy, matched in a Group. The Docker Deamon is configured to use this group as registry mirror.
Now we want to add a private registry to this registry mirror group. I configured the new registry in nexus as proxy with its own port and pulling images works perfectly.
Then I added this proxy to the registry mirror group, but it is not possible to pull the images over the group.
Nexus logger output:
Is the remote url a valid docker endpoint? Remote host https://<private-reg>:5000/ with path /v2/library/<image-name>/manifests/v0.0.1 did not return the expected response. Error message: manifest unknown
The private registry is using the offical Docker registry and the path to the endpoint should looks like this:
https://<private-reg>:5000/v2/_catalog for the whole images
It seems similar to this issue:
Or is there a way to configure the path to the catalog?
