[JBoss] Which Docker registry should be used for Keycloak?

Running from a docker compose file

keycloak:
image: jboss/keycloak
container_name: keycloak
restart: always
environment:
KEYCLOAK_USER: admin
KEYCLOAK_PASSWORD: admin
ports:
- "8080:8080"


Works for me, where "works" means: if I create a realm called wibble (redirect urls *) and a user called user1, when I go to http://localhost:8080/auth/realms/wibble/account I get a login prompt.

On doing the same thing for quay.io, the same url gives a "We are sorry, page not found" response

keycloak:
image: quay.io/keycloak/keycloak:latest
command: start-dev
restart: always
environment:
KEYCLOAK_ADMIN: admin
KEYCLOAK_ADMIN_PASSWORD: admin
ports:
- 8080:8080


Also, using the keycloak image from quay.io, http://localhost:8080/ redirects to http://localhost:8080/auth/ which also give the same "We are sorry, page not found" response but going to http://localhost:8080/admin gives a login prompt.

Am I right in thinking that the quay.io image is the more recent and supported one? And if so, does anyone have any ideas what on earth is going on with that simple docker compose file?
