[question] best way to run multiple instances of x?

same problem would happen if you have multiple redis/mongo replicas ..etc.
and yes, you need to customize ports, unfortunately this is not easy for example in mysql you need to edit /etc/my.cnf but in redis you can pass --port 7777, like this

version: '3'
services:
  redis:
    read_only: true
    image: redis:alpine
    command: ["redis-server", "--port 7777", "--appendonly yes", "--notify-keyspace-events", "Ex"]
    volumes:
    - ./data/redis:/data
    tmpfs:
    - /tmp
    - /var/run
    - /run

podman-compose have multiple mapping modes
the default one 1podfw and alike (1pod, hostnet, cntnet, and publishall)
the end result would be that all containers would share same network namespace
resulting that you can listen to the same port (because it's same port on same namespace)

the only one mode that does not have this problem is identity (which does not do any change, it actually run multiple containers each in it's own network namespace),
but for that to work you need sudo not rootless (which is the objective of this project),
that's why I did not implement it (if you want to use sudo podman-compose then tell me I might give it a priority)

the actual reason why rootless containers can't talk to each other is not related to podman-compose
but it's related to slirp4netns

podman uses cni to configure network.

if there is a way to do it in slirp4netns or cni or if there is a way , or if you created an issue there ping me and reopen this issue.

please close this issue if I answered your question

hmm, that's unfortunate, thanks for the reply
