I see many questions, thought I'd make a post :-) So when running Lemmy in Docker, you'll see your `/` filesystem gets filled up quickly. That's mainly in `/var/lib/docker/containers`. It's the logging of the containers. Docker will default save all logging. Also when you `docker-compose stop` and restart, the logging stays. Only when re-creating the containers (`docker-compose down;docker-compose up -d`) it will clear the logs. ## Why is my container logging this much? In the `docker-compose.yml` you'll see an environment variable `RUST_LOG=` which is set to `info`. This logs all informational messages. You can set this to `warn` instead to only get warning and error messages. (Requires container recreate) ## How to manually cleanup the log without restart You can find the log of a container with ``` docker inspect --format='{{.LogPath}}' <containername> ``` You can then wipe it by typing `'> '` (so greater than followed by space) followed by the file path+name. (Removing it while the container runs wil not really remove it, you'll just no longer see it but it still exists and grows as long as the container runs) ## How to prevent logs from growing too large You can set a max for log file size in your `docker-compose.yml` using these lines for every container: ``` logging: driver: "json-file" options: max-size: "100m" ```
