Description
Describe the bug
Despite to the container used network_mode: host default network is also applied in the command line later and has precedence!
To Reproduce
Minimal docker-compose.yml file to reproduce problem:
version: '2.4'
services:
apache:
container_name: podman-compose-bug-reproduce
image: docker.io/httpd:2.4.52
# ports:
# - 80:80
# To use ports less than 1024 in rootless mode that require allow priveledged ports use. E.g. (or similar in sysctl.conf):
# sudo sysctl net.ipv4.ip_unprivileged_port_start=70
network_mode: host
hostname: 127.0.0.1Run it:
$ podman-compose up -d
['podman', '--version', '']
using podman version: 3.4.4
** excluding: set()
['podman', 'network', 'exists', 'podman-compose-bug_default']
podman run --name=podman-compose-bug-reproduce -d --label io.podman.compose.config-hash=123 --label io.podman.compose.project=podman-compose-bug --label io.podman.compose.version=0.0.1 --label com.docker.compose.project=podman-compose-bug --label com.docker.compose.project.working_dir=/home/pasha/temp/podman-compose-bug --label com.docker.compose.project.config_files=docker-compose.yml --label com.docker.compose.container-number=1 --label com.docker.compose.service=apache --network host --net podman-compose-bug_default --network-alias apache --hostname 127.0.0.1 docker.io/httpd:2.4.52

Get working Apache httpd welcome page.
Actual behavior
Got an error what the port is not open.
Please note, in the actual command line for the podman present sequentially: --network host --net podman-compose-bug_default, so if I manually re-run such container without --net podman-compose-bug_default that will work:
$ podman rm -vf podman-compose-bug-reproduce

<html><body><h1>It works!</h1></body></html>I also tested that behaviour with previous version of podman-compose (in Fedora 35 that is 0.1.8), and it generate expected (working) run command, please look:
$ sudo dnf downgrade podman-compose -y
...
Downgraded:
podman-compose-0.1.8-1.fc35.noarch
Complete!
$ podman-compose down
...
