Example of primary and replica whith pgPool

[mpkthomasa]

Hi,

I have two containers primary and replica running crunchydata/crunchy-postgres:centos7-11.8-4.4.0 in a Docker swarm.
docker stack deploy is used to deploy from a compose file.

Now I would like to add pgPool to the compose file to handle replication and load balancing, i would like to have a cluster of three pgPool containers to avoid single point of failure.
Unfortunately, I have not been able to find a good example or description of how to do this in the best way.

Could anyone show me how to do this?

Thanks in advance
