Log rotate on restart and at midnight

This is what I found today too but AFAIK it’s not passed to the supervised:

[FR] Log file rotation/truncation for Logger Component

Starting from version 0.107 there is no easy way to pass a --log-rotate-days argument to a HA bootstrap script inside a Docker container. They switched to s6 supervisor and the only option I see is to replace a service file (https://github.com/home-assistant/core/blob/bd28a9f99bd927d4c01f08ac78048a49220d0d12/rootfs/etc/services.d/home-assistant/run). Theoretically you can setup logrotate, but I don’t know how HA will react on truncated log file. Previously you could just set up ["python", "-m",…

Some other discussions:

Log rotate

Yeah , thats a big AO, people have to learn about the consequences of their actions, such as keeping backups forever, logging/writing every tiny details, in DB, and storing logfiles. Actually such basic Info(knowledge) should be “punched” in (somehow/somewhere), as many new users , doesn’t know the impact or relevance

Log file may become too large, "max_entries" does not work

Better logging

I think the home assistant os should have this option natively (natively running an ssh server outside of the actual home assistant app), so that you don’t need to be a hacker. Or at least don’t clear the logs upon restart so that we less-hacky people can give them their logs when doing error reports.

How can I rotate / limit the size of home-assistant.log file in docker

I’ve found a lot of topics about limiting the size of this file, but most seem to only talk about command line options, like --log-rotate-days. I run HA from a docker-compose file, so AFAIK, I can’t use command line options. So, to keep it short: In 2023, running HA in a Docker container, how do we limit the size of the home-assistant.log file found in the config folder?

hass --log-rotate-days ..., rotated log file is overwritten

How to automatically purge home assistant log?

In my case, I have no logger entry in configuration.yaml. Nevertheless, there is a home-assistant.log file and it’s about 82 Kb. Whatever I see in there is also found in /var/log/syslog. The home-assistant.log file is automatically purged after every restart whereas the duplicated entries in syslog are retained. Anyway, that’s how it works on my system (version 0.89 in a venv).
