[keycloak-dev] Docker Protocol?

[Josh Cain]

Hi Stian,

Docker's auth V2 (docs link above) is Oauth-ish, but doesn't seem to
conform 100% to the specification.  I started by just trying to stand up an
OIDC endpoint to talk to docker and Keycloak threw a "Missing parameters:
response_type" error.  Turns out, Docker sends the GET request like this:

/auth/realms/redhat-external/protocol/docker-v2/auth?account=jcain&scope=repository%3Acentos%3Apull&service=docker-registry

Not only is the request missing the request_typer paremeter, but Docker
uses different nomenclature than the OAuth/OIDC standard.  For instance, I
would expect the 'service' param to appear as the client_id param to
conform to the OAuth spec.

Since it uses different nomenclature, I thought it would be a much cleaner
implementation to just implement it as its own protocol.  Didn't want to
muddy up a clean OIDC/OAuth implemention.

Are there workarounds to deal with these differences that I'm missing?
