From time to time I had the issue that Traefik for some Docker containers returned Gateway Timeout instead of the website under the configured URL. Accessing the page via an exposed port easily showed that the container was working fine. And I observed that it only happend for Stacks with multiple services running.
I have traefik in a docker container running on TrueNAS Fangtooth. The log can grow over time and traefik supports log rotation via logrotatecommand. But how to do this on TrueNAS with a docker container?
