I am thinking of moving all our stateful services to use petset. Check out this link for more information on petset. Postgres, Kafka, Zookeeper and Redis will be affected by this change. This will be an experiment and shall be conducted in a small kubernetes cluster.
###Postgres I don't think there is any very reliable configuration we can use. Let's take a look at postgres k8s for inspiration.
###Kafka We can leverage all/any of this solution.
###Redis We can leverage all/any of this solution.
###Zookeeper We can leverage all/any of this solution.
