There are docker logs that can grow to fill all available disk space if you don’t prevent it.

For it, we can use the max-size on the( daemon configs runtime or compose / stack).

The log file is located inside the container folder and the default one is a JSON file.

/var/lib/docker/containers/CONTAINERUUID/CONTAINERUUID-json.log

We can set it to

logging:
  options:
    max-size: 50m

On Portainer, we can set it on the stacks or on the container create/edit page.
