I was having issues with the container restarting automatically whenever a license plate was being processed. Logs in /config/frigate_plate_recognizer.log:

which shows the container restarting but apparently for no reason.

After checking docker container logs:

which shows a different story.

The way the Dockerfile calls python directly is the source of the issue. I don't know how you would prefer to handle this, to me the first solution that comes to mind would be to keep the logger logging out to stdout but not to the file. Then modify the launcher command either directly in the Dockerfile or create a run.sh like:

#!/bin/bash
python index.py >>/config/frigate_plate_recognizer.log 2>&1

Hi, I'm having the same issue. Can you elaborate on your solution. Many Thanks!
