Docker container logs taking all my disk space

CAUTION: This is for docker-compose version 2 only

Example:

version: '2'
services:
  db:
    container_name: db
    image: mysql:5.7
    ports:
      - 3306:3306
    logging:
      options:
        max-size: 50m

Docker 1.8 has been released with a log rotation option. Adding:

--log-opt max-size=50m 

when the container is launched does the trick. You can learn more at: https://docs.docker.com/engine/admin/logging/overview/
