[keycloak-user] KEYCLOAK_FRONTEND_URL and KEYCLOAK_HOSTNAME

Hi, I am struggling with the introduction of the new KEYCLOAK_FRONTEND_URL env variable. As I was unable to find documentation about it within 5 minutes and we want to support a KC 7 and 8 in parallel, I simply tried to set both variables at the same time. This fails due to the following piece of code (server/tools/docker-entrypoint.sh): ... ############ # Hostname # ############ if [[ -n ${KEYCLOAK_FRONTEND_URL:-} ]]; then SYS_PROPS+="-Dkeycloak.frontendUrl=$KEYCLOAK_FRONTEND_URL" fi if [[ -n ${KEYCLOAK_HOSTNAME:-} ]]; then SYS_PROPS+="-Dkeycloak.hostname.provider=fixed -Dkeycloak.hostname.fixed.hostname=$KEYCLOAK_HOSTNAME" ... There is a space missing in the KEYCLOAK_HOSTNAME handling (SYS_PROPS+=" -Dkeycloak.hostname.provider=f") Due to that, the result is the following in KC logs: 2019-12-10 11:12:46,664 INFO [org.keycloak.url.DefaultHostnameProviderFactory] (ServerService Thread Pool -- 70) Frontend: myCustomHostname-Dkeycloak.hostname.provider=fixed, Admin: <frontend>, Backend: <request> So is setting both variables at the same time a way to go (assuming I set KEYCLOAK_FRONTEND_URL to "myCustomHostname " (space at the end)? Is this supported? Is there any documentation available, maybe also about the difference to KEYCLOAK_HOSTNAME?
