Hi all, I cannot find any documentation in regards to deploying a sql gateway on kubernetes. The only documentation I see suggests that I need to build a custom docker image, overriding the COMMAND to the /bin/sql-gateway.sh command. Is this really necessary? Or is there some fields I can override in the Flink Kubernetes Operator Custom Definitions that can configure the official docker image to run the /bin/sql-gateway executable instead of the /bin/flink cluster executable?
