Can we setup Rancher in HA mode behind PostgreSQL DB ? In the docs , it mentions about MySQL only. If it supports PostgreSQL do we have documents on how to configure Rancher in HA mode
The only “supported” database is MySQL (and compatible variants). There was experimental support for Posgtres contributed by a user and merged in a while ago, but it does not work with the current catalog service which makes it basically unusable in current versions.
