Podman Quadlets Arr-Stack And Networking
Podman Quadlets Arr-Stack And Networking
I need some help if anyone could take the time and has the knowledge:
I'm basically new to podman and namespaces, relatively new to linux and a noob at networking. So figuring this out and getting it to work took many more hours than I would like to admit, but I still have a few problems. I have all my current Quadlets below in the spoiler (seperated by "---", assume user123 = UID 1000). I am on Bazzite, rootless Podman, which probably makes this even harder.

Questions:
- If I use "podman exec
<container>
ip route" (on e.g. qbittorrent) the default route goes through my actual network interface (actual ip adress) which I very much do not want (or through my killswitch dummy network from my VPN if on, which is better but still not ideal). Is there a way to completely remove my actual network from a container's eyes? "podman exec<container>
ip addr" shows 1 lo (local), 2 my actual network, 4 tun0 from gluetun. The traffic does go through gluetun correctly, but I don't trust it 100%. Having the containers separated and NOT inside a pod gives the same result, since the containers share the network namespaces from the gluetun container when I do "Network=container:gluetun" (same as just having them in a pod as far as I understand). I tried to also create a podman network without a default gateway, but then gluetun cannot connect to the VPN in the first place.
- If I use "podman exec
- My setup works but is quite convoluted and probably has many unnecessary lines, so please give me any improvements you see
- Is User=1000, Group=1000, even sensible? For example in the homepage container those lines result in the container showing User "1000:1000" (from podman inspect). Would User=0, Group=0 (or no lines since I use UserNS=keep-id in the pod?), which shows as User=root (podman inspect) mean that it has actual root access or just that it is root INSIDE the container?
Thank you in advance for the answers, in case I don't reply to your comment specifically.
