I am trying to setup HA rocket chat with kubernetes. According to the rocket chat HA guide, rocket supports HA. I assume StatefulSet should be used to support such records:
extra_hosts: - "rocket-1:10.250.250.13" - "rocket-2:10.250.250.14" - "rocket-3:10.250.250.17"
However i still miss some parts of the puzzle. Where in kubernetes can i specify extra_hosts? Is where any guide of how to achieve it?
