How to configure Docker Compose with equivalent to -d option (detach)

Question

The following command runs a container with mysql in the background.

docker run -d -p 3306:3306 -e MYSQL_RANDOM_ROOT_PASSWORD=yes --name mysqldb mysql

The equivalent with the docker-compose.yml would be:

version: '2'

services:
  mysqldb:
    image: mysql
    ports:
      - 3306:3306
    environment:
      MYSQL_RANDOM_ROOT_PASSWORD: yes

But when I spin using docker-compose up the process stays in the foreground. How do I add the equivalent of the detach option (-d) of docker container run?

Answer 1

You can use the command: docker-compose up -d. This command starts the containers in the background and leaves them running. Learn more in the Docker documentation https://docs.docker.com/compose/reference/up/.
