SIP in docker container

[mimer]

Hi all,
   I have just installed SIP into a container (via git), exposed the port 80 and started off the service by python3 sip.py from /SIP within the container.
  Everything worked out, service is reachable....
   However, I tried to enable the relay_16 plugin and got the following reported by sip on the console:

 The browser reported back in a (I guess browser provided window):

SIP could not restart
Please restart the programm from command line

This I did and the plugin is showing up...everything sees ok...
Somebody has an idea to overcome that restart-step? or can somebody maybe post a working Dockerfile and a docker run ....?

Many thanks for your support!

Kind regards,
