Running docker compose up outputs logs even when logging driver is set to none

Question

I'm using docker-compose to run tests for my app. My docker-compose.yml file has three services, one for mongodb, one for my app, and a third for my tests. I have logging: driver: "none" set for the app and mongodb because I only want to see the test logs.

This previously worked as expected. Since the last time I worked on this project, I've upgraded docker desktop on my mac to Version 3.5.2 (3.5.2.18). Now, all container logs flood my terminal when running. I'm not sure what has changed.

version: '3.1'

services:

  mongodb:
    image: mongo
    expose:
      - 27017
    logging:
      driver: "none"

  rsscloud:
    build: .
    command: node --use_strict app.js
    environment:
      DOMAIN: rsscloud
      PORT: 5337
      MONGODB_URI: mongodb://mongodb:27017/rsscloud
      NODE_TLS_REJECT_UNAUTHORIZED: 0
    expose:
      - 5337
    depends_on:
      - mongodb
    logging:
      driver: "none"

  rsscloud-tests:
    build: .
    command: dockerize -wait tcp://mongodb:27017 -wait http://rsscloud:5337 -timeout 10s bash -c "npm test"
    environment:
      APP_URL: http://rsscloud:5337
      MONGODB_URI: mongodb://mongodb:27017/rsscloud
      MOCK_SERVER_DOMAIN: rsscloud-tests
      MOCK_SERVER_PORT: 8002
      SECURE_MOCK_SERVER_PORT: 8003
    volumes:
      - ./xunit:/app/xunit
    expose:
      - 8002
      - 8003
    depends_on:
      - mongodb
      - rsscloud

I run docker compose up --build --abort-on-container-exit

Here is a sample of the output:

Answer 1

This is an intentional change with docker compose. You can change it back to using docker-compose which is different from docker compose and will likely provide your expected previous behavior.

Or you can run docker compose up -d and docker compose logs rsscloud-tests but I'm not sure there's an easy way to do that with --abort-on-container-exit since that's likely incompatible with the -d option.

Answer 2

As a complement of the given answer:

Now we're able to use:
docker compose up --attach service_name

This will attach the output to the service_name, showing logs just from this service.

PS.: This command only works on docker compose V2 version which already have a good support for Docker on Windows, but when it comes to linux, the --attach argument isn't very well implemented so far. For linux, I would advise to keep using logging driver (setting it to none if you wish docker not to output logs), running docker-compose V1. You may find more information about docker compose V2 at the docs:
