Hello,
While deploying Keycloak 4.5.0.Final in an Openshift environment, using
Mariadb (Galera) as a database produces several exceptions in the logs, all
of them being related to the communication between the Keycloak server and
the database. The access to the Galera server (3 instances) is performed
via a Maxscale proxy. The Galera server, Maxscale (deployment of 3 pods)
and Keycloak (deployment of 2 replicas) are all deployed inside Openshift,
on AWS (1master + 3 workers).
I am hoping you guys can help with fixing these issues.
The errors look like below:
08:40:46,603 WARN

I suspect that the errors come from the way the jdbc data source is
configured. The mariadb configurations related to connections and wait
timeouts are like below:
max_connections=1000
wait_timeout=180
The second issue I noticed was the following: one of the pods in the
deployments (we deploy 2 replicas of Keycloak) sometimes does not start
correctly because of the following exception, which is still related to the
database connection:

The pod is restarted several times it seems, but it does not start
correctly. I deleted the pod and it was recreated automatically by
Openshift and the new pod started correctly.
Then, there is a third issue that I've encountered while trying to login
into the deployed application. While entering some wrong credentials I got
an error page and noticed in the logs that there is still a database
connection error:
