This one made me wonder; I see we're constructing token handlers in different places; for this one, and some paths in docker/docker, we set the ClientID; https://github.com/moby/moby/blob/330857ad0ffbc8114556f7886997fc43d7be4aad/distribution/registry.go#L123

But in cli/registry/client we use auth.NewTokenHandler

cli/cli/registry/client/endpoint.go

Lines 95 to 96 in 2b0631f

	creds := registry.NewStaticCredentialStore(&authConfig)
	tokenHandler := auth.NewTokenHandler(authTransport, creds, repoName, actions...)

Which means we end up with github.com/docker/distribution picking a default;

cli/vendor/github.com/docker/distribution/registry/client/auth/session.go

Lines 328 to 332 in 2b0631f

	clientID := th.clientID
	if clientID == "" {
	// Use default client, this is a required field
	clientID = defaultClientID
	}

Which would be registry-client

cli/vendor/github.com/docker/distribution/registry/client/auth/session.go

Line 28 in 2b0631f

const defaultClientID = "registry-client"
