There is missing declaration of userSessionPersister in the keycloak-server.json file. I bet that if you add this: "userSessionPersister": { "provider": "jpa" }, to the file https://github.com/jboss-dockerfiles/keycloak/blob/master/server-ha-postg..., the things will start to work. Will be cool if you could doublecheck and possibly send PR if it helps :-) The even more proper solution will be to avoid having keycloak-server.json in the docker image, as the file becomes outdated during each update in Keycloak. Docker image should have some script or something to edit the existing file "on the fly" and update it to use cluster. Actually not sure if separate keycloak-server.json is still needed as in latest Keycloak, keycloak-server.json already contains configuration for connections-infinispan (which it wasn't before AFAIK) Marek On 14/12/15 11:52, Thomas Darimont wrote: Starting the Keycloak Postgres HA Docker Image fails due to a problem with loading OffilineUserSessions - see stacktrace below. There is an already resolved?! issue https://issues.jboss.org/browse/KEYCLOAK-1999 filed for Keycloak 1.6.0 that shows some workaround suggestions, but I think disabling the support for offline sessions is not a fix to the actual problem... Would be great to have a real fix, since this hinders the Keycloak Server to start.
