Disable logging for one container in Docker-Compose

I have a web application launched using Docker compose that I want to disable all logging for (or at the very least print it out to syslog instead of a file).

When my web application works it can quickly generate an 11GB log file on startup so this eats up my disk space very fast.

I'm aware that normal docker has logging options for its run command but in Docker Compose I use

docker-compose up

in the application folder to start my application. How would I enable this functionality in my case? I'm not seeing a specific case anywhere online.


Solution 1:

You should be able to use logging feature. Try to set driver to none

logging:
    driver: none

Full example:

services:
  website:
    image: nginx
    logging:
      driver: none

In recent versions of docker-compose, if all of the services have disabled logging, docker-compose will act as in detach mode. To force the attached mode you can add a simple silent service like that:

services:
  website:
    image: nginx
    logging:
      driver: none

  force-attach:
    image: bash
    command: tail -f /dev/null

Solution 2:

For a quick config example, something like

version: '3'
services:
    postgres:
        image: postgres:9.6
        logging:
            driver: none 

Solution 3:

As the second option, you may be interested in not fully removing logging (what 'none' value does), but in storing logs of some services in syslog, there is the driver for it, for instance:

certbot:
  image: certbot/certbot
  restart: unless-stopped
  logging:
    driver: "syslog"

Note that the syslog daemon must be running on the host machine. To see the logs use for example: journalctl -n 100 --no-pager
