[keycloak-user] Invalid token issuer when running as docker service

Hello, got the follwing setup: - frontend (oauth, angular2) - rest-backend (bearerOnly, spring-boot with spring-security) - keycloak (standalone) If I run the three as "ordinary" processes, everything works fine. However, if I try to run them as services within a docker (swarm mode) the rest-backend keeps complaining about: org.keycloak.common.VerificationException: Invalid token issuer. Expected 'http://myhost:8180/auth/realms/myrealm', but was 'http://localhost:8180/auth/realms/myrealm' I inserted myhost into my /etc/hosts to point to the IP of docker0. So far it works, I can access the frontend on port 80 and keycloak on port 8180. Is there a way to make keycloak report as myhost in the issuer token and not as localhost? Tried running keycloak behind a reverse-proxy - no change.
