Enabling a quadlet container that can connect back to the host

[flixman]

Hi! I have the following files defining quadlets. My problem is that from the container I cannot connect back to the host. I am creating a new network because I have read that the bridge network that is already existing cannot be configured after started. I have added an option to that network, but... It is still not working and I cannot see what I am doing wrong:

~/.config/containers/systemd/podman-gitea-redis.container

[Unit]
PartOf=podman-gitea-pod.service

[Service]
Restart=always

[Container]
Image=docker.io/library/redis:alpine
Pod=podman-gitea.pod

~/.config/containers/systemd/podman-gitea-gitea.container

[Unit]
Requires=podman-gitea-redis.service
After=podman-gitea-redis.service
PartOf=podman-gitea-pod.service

[Service]
Restart=always

[Container]
EnvironmentFile=%h/gitea/config/gitea.env
Image=docker.io/gitea/gitea:latest
Pod=podman-gitea.pod
Volume=/home/ubuntu/gitea/data:/data
Volume=/etc/localtime:/etc/localtime:ro
Volume=/home/ubuntu/ca.crt:/etc/ssl/cert.pem:ro

~/.config/containers/systemd/gitea.network

[Network]
Options=pasta:--map-gw

~/.config/containers/systemd/podman-gitea.pod

[Pod]
PublishPort=10.44.0.1:3000:3000
Network=gitea.network

[Install]
WantedBy=default.target

[flixman]

Seems to be fixed by not using an ad-hoc network and, instead, using AddHost at the pod level, pointing to host-gateway. Is this the recommended approach?

If you're using a recent version of Podman and rootless containers, you might want to check https://blog.podman.io/2024/10/podman-5-3-changes-for-improved-networking-experience-with-pasta/.
