Docker CLI client not correctly authorizing to private registry with token auth about distribution HOT 1 OPEN

This is a question for https://github.com/moby/moby project I believe. CC: @thaJeztah

My general suspicion is: docker daemon does not seem to be able to handle calls to private registry. I am going to assume that your private registry is served over trusted TLS cert otherwise you'd need to explicitly tell docker daemon it is untrusted i.e. insecure in docker daemon.json settings. If you dont, the daemon will barf. The config goes something like this IIRC -- please check the official docs.

{
  "insecure-registries" : ["<my-registry-ip>:5000"]
}

If the registry does serve the API using a trusted TLS cert then yeah, please ask in moby/moby.

Finally, I'd strongly encourage you to stop using v2.8.x version. It's missing a lot of patches, bug fixes and performance improvements.

from distribution.
