FWIW, I'm also very much leaning towards moving this information to the Client: section, because nothing about it is part of the "Server:".

I think this was historically because it depended on the server (?) but no real idea.

Also;

  • because it's not part of the actual info.Info struct (i.e., the Server part), it's currently not even possible to use docker info --format <template> to show the name
  • ^^ so docker info --format=json won't show it
  • ^^ AND if a credentials-helper is used, it's not even filled in at all (it only looks in the config file
  • 🙃 🤷

So ... perhaps we should either remove it altogether, or make it use the actual credential-store in use, BUT reading info from that is not always .. fast, and I don't want docker info to become slow 😓
