Cannot use service name to exchange visits

[ktpktr0]

os --verson: Rocky Linux release 8.6 (Green Obsidian) podman-composer version: 1.0.3 podman --version: 4.0.2

I use podman compose to compose my services. They are already under the same network, but the service name cannot be resolved:

Under the same configuration, docker compose can be parsed normally

as you can see in this comment

make sure you have netavark and aardvark-dns installed and make sure to remove containernetworking-plugins

and make sure podman info show netavark not oci

$ podman info | grep -i -A3 net
  networkBackend: netavark

check this article for details

[ktpktr0]

After installing netavar and Aardvark DNS, I modified /usr/share/containers/containers Conf file, change networkbackend: CNI to networkbackend: netavar, and it works normally

Whether podman is incompatible with nftables. When nftables is used, the port cannot be accessed; Iptables is normal.

Thank you for your
