Hi Team,
We are planning to build a HA setup with pgpool in docker, Could you please let us know prerequisites for it.
1. How many servers are needed for this?, can we plan with 2 servers like below config.
Primary instance and pgpool in two different docker containers in server 1 and standby instance in docker container server 2.
2. User requirement: any user needs password less authentication between nodes.
3. Port or firewall rules between servers.
4. If planning to create a network bridge between all docker containers between 2 servers will be any prerequisites for that.
Thanks in advance.
Regards,
