I'm having some trouble using the keycloak operator installing on a simple Kubernetes Cluster on Karbon
Basically, what happens is that when I install a new Keycloak, the PostgresSQL is not able to run properly because it does not have permissions to create a new directory on /var/lib/pgsql/data/userdata
As far as I understood, the problem is related to the securityContext which is not set to the postgres deployment even if Postgres runs always using user 26 (as can be noted here: https://catalog.redhat.com/software/containers/rhscl/postgresql-10-rhel7/5aa63541ac3db95f196086f1?container-tabs=dockerfile)
I had to do a lot of workarounds to make it work, and finally I succeded by configuring manually the security context as follows:
There is any possibility to set the security context via the operator? if not, can you please point me out what is the correct solution to apply?
