Variable for PublishPort in systemd .container

[LangDuTienTu]

Atm if I use variable for PublishPort such as PublishPort=${PORT}:${PORT}, quadlet dryrun would show error message and quadlet cannot generate systemd service

invalid port format '${PORT}'

While we may use variable for Volume, why not PublishPort :3

Thanks for reporting this.

The reason it does not work for ports is that Quadlet does some validation checks: https://github.com/containers/podman/blob/main/pkg/systemd/quadlet/quadlet.go#L1957. But, I'm not sure it should still do them.

@vrothberg @Luap99 @rhatdan WDYT?

[LangDuTienTu]

Glad that you all agree with the idea, hope it would be in the next podman asap

@LangDuTienTu, would you open an issue for it? That lets us better track the fix and users can subscribe to it.
