   Thx @potiuk, resolved the issue with the /tmp folder permissions. In the systemd service the option PrivateTmp=True was set which was the root cause of it. But still the docker operator doesn't execute successfully.
   
   ````bash

   ````
   
   I guess the operator tries to pull the image and the corresponding connection details are missing.
   However, the image is already on the host, so a docker pull shouldn't be executed per default.
