smoloney/docker-log-cleaner repository overview

⁠log-cleaner

⁠Features
  • A standalone docker container.
  • Designed to clear the log files for a docker container at specified intervals.
  • Can be used for clearing logs in multiple containers.
  • Only functional with the driver: "json-file".
⁠Startup commands
sudo docker-compose up -d

force recreate and show logs

sudo docker-compose up -d --build --force-recreate && sudo docker-compose logs -f
⁠Environment variables
  • CLEAN_FREQUENCY - an integer and represents seconds so 60 = 1 minute, 3600 = 1 hour
  • CONTAINERS_T0_CLEAN - the container_name of the containers to have their logs cleaned.
  • INCLUDE_SELF - whether the current container (log-cleaner by default) should also have it's logs cleaned, defaults to TRUE
  • SELF_NAME - name of the current container (defaults to log_cleaner)
⁠Examples

The following docker-compose.yml example will clear the logs of containers with names mongo nginx every 3600 seconds (hourly)

version: '2'

services:

  log-cleaner:
    image: smoloney/docker-log-cleaner:latest
    build:
      context: .
      dockerfile: Dockerfile
    container_name: log-cleaner
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /var/lib/docker/containers/:/var/lib/docker/containers/
    environment:
      - CLEAN_FREQUENCY=3600
      - CONTAINERS_T0_CLEAN=mongo nginx
      - INCLUDE_SELF=FALSE
    logging:
      driver: "json-file"
      options:
        max-size: "1m"
        max-file: "1"

The following docker-compose.yml example will clear the logs of containers with names mongo nginx my-logger-cleaner every 3600 seconds (hourly)

  log-cleaner:
    image: smoloney/docker-log-cleaner:latest
    build:
      context: .
      dockerfile: Dockerfile
    container_name: my-logger-cleaner

    - INCLUDE_SELF=TRUE
    - SELF_NAME=my-logger-cleaner
    logging:
      driver: "json-file"
      options:
        max-size: "1m"
        max-file: "1"
⁠Notes
  • This project is not designed as a replacement for the docker-compose logging directives⁠ but rather as an adjunct to the logging directive.
  • If this feature is implemented in docker then this project will become defunct and hopefully this will be the case. There was an issue about this⁠ in docker/compose in github.
