#Drupal logs driver

There does not appear to be a way to change the logging options of an existing container, so you will need to recreate your containers to apply these changes. You can override this on an individual container by passing the log options on your run command (or inside the compose file): docker container run -log-opt max-size=5m -log-opt max-file=2. You need to trigger a reload on the dockerd process to load this file ( killall -HUP dockerd or systemctl reload docker). The result is a limit between 20-30 megs of logs per container. Those two options say to keep up to 3 different 10 meg JSON log files.

I typically set these options with new default values for all containers being run on the docker host using the following lines inside my /etc/docker/daemon.json file: Installation and use The Simple Access Log module can be installed like other Drupal modules by placing this directory in the Drupal file system (modules directory) and enabling on the Drupal Modules page (/admin/modules). max-file: this limits the number of JSON log files that will be created up to the max size set above. Due to the way Drupal 8/9/10 Handles caching for anonymous users this module currently struggles with logging their visits.After this, docker will create a new file. max-size: this limits how large a single JSON log file will grow to.However, there are two log options you can adjust when starting a container with the default JSON log driver. So the I'm not sure there's an option to do exactly what you are asking.

The default setting for the log driver is a JSON file format, and the only way I can think of to reliably parse that involves parsing the file from the beginning, which I suspect is exactly what docker does.
