How to split bitnami postgres HA replication image into 2 nodes?

Question

PostgreSQL

There are 2 nodes that need to deploy streaming replication as a failover solution.

Found docker image: bitnami-docker-postgresql-repmgr the only thing that doesn't work is splitting the master replica into 2 hosts.

I tried to fix docker-compose for swarm, as a result there is a network connection error.

If it is possible to combine on 2 hosts into one docker network and then add a container with the parameters of this network on the 2nd host, tell me how this can be done?
