Multiple bitnami pgpool-II container

Question

Need clarification if this is doable. I have successfully ran Postgres with 2 containers namely master and slave. I would like to know if I can run more than one pgpool container ? If yes, is there any specific environment variables i need to set ?

Can I just take the below command and run in another pgpool VM ? My intention is to have a load balancer round robin between the 2 pgpool that connects to the backend of master (rw) and slave (ro).

docker run --detach --rm --name pgpool \
  --network my-network \
  --env PGPOOL_BACKEND_NODES=0:pg-0:5432,1:pg-1:5432 \
  --env PGPOOL_SR_CHECK_USER=customuser \
  --env PGPOOL_SR_CHECK_PASSWORD=custompassword \
  --env PGPOOL_ENABLE_LDAP=no \
  --env PGPOOL_POSTGRES_USERNAME=postgres \
  --env PGPOOL_POSTGRES_PASSWORD=adminpassword \
  --env PGPOOL_ADMIN_USERNAME=admin \
  --env PGPOOL_ADMIN_PASSWORD=adminpassword \
