Systemd Integration Restart Loop

[iamzoltan]

hey, thanks for this great docker! It was exactly what I was looking for. I got the docker running and working and everything was A OK. The only trouble is that when I follow your instructions to try to turn transmission-openvpn into a systemd service, it constantly restarts and can not seem to stay running. Any ideas? Here is the .service file

haha, nevermind.... I think I found the issue. I removed the -d flag from this line:

--cap-add=NET_ADMIN -d

and it stopped restarting. :)

Any idea why that would happen? the man says its -d is detach mode, meaning its running in the background, but I'm not sure why that would cause the service to constantly restart.

thanks for your time!

Uhm, adding -d to the systemd doesn’t make sense though as it’s already in the background and no need for detach.. you can attach the log and we can see what it says though
