Review comment:
ENSURE_OM_INITIALIZED is not required here. For kubernetes we follow a
different (more generic) approach. We can define an 'initContainer' to execute
the 'om --init' first. (as you can see this is the initContainer here). As the
'om --init' can be executed multiple times it works well without the
environment variable (which is handled by the starter script of the container.
