Hello,

I have a working keycloak cluster with docker instances on separate nodes clustered with JDBC\_PING.  
When starting the instances **with** external postgresql reachable, everything is fine. Stop the db and restart it later works well. Keycloak automatically reconnects.

The problem I have is when starting keycloak **without connectivity to the db**. In this case the container restarts every N seconds, which is fine (restart=unless-stopped).  
When the db becomes available, keycloak does not detect it on the next start. It just keeps restarting  
The only way to make it work is to do a docker-compose down && docker-compose up -d

Any suggestion on how to make it work properly?
