Hello experts,
I'm having issues getting two containers reach each other with rootless podman-compose. Tested using a simple test compose file.
Reference links and my findings.
https://github.com/containers/podman/blob/main/docs/tutorials/basic_networking.md, (also tried using $host IP, in compose file)
https://github.com/containers/podman/blob/main/docs/tutorials/rootless_tutorial.md
https://github.com/rootless-containers/slirp4netns#usage, (at step Make sure the tap0 is configured and connected to the Internet, i have no tap0 interface )
slirp4netns --version
slirp4netns version 1.2.0
commit: unknown
libslirp: 4.7.0
SLIRP_CONFIG_VERSION_MAX: 5

What did I miss how can I get container1 to ping container2?
Thank you for your time.
