Containers that log heavily can fill disks. The fix is boring and should be done on day one: set log rotation caps and confirm they are actually active on the running container.
Sane defaults
logging:
driver: "json-file"
options:
max-size: "50m"
max-file: "5"Verify what is active
docker inspect <container> --format '{{json .HostConfig.LogConfig}}'If you changed the compose file but did not recreate the container, the old settings may still be in effect. Use a force recreate when you need to be sure.
