    Docker-compose commands for container management

    Date: 17.07.2020

    Category: DevOps

    The docker-compose is a useful tool for orchestrating multi-container Docker applications. It allows us to run applications based on a YAML file. This file is a list of instructions that define the parameters of the launched applications. For example, we can run two containers – database MySQL and base web application WordPress. The docker-compose files might look like this:

    version: '3.3'
         image: mysql:5.7
           - db_data:/var/lib/mysql
         restart: always
           MYSQL_ROOT_PASSWORD: somewordpress
           MYSQL_DATABASE: wordpress
           MYSQL_USER: wordpress
           MYSQL_PASSWORD: wordpress
           - db
         image: wordpress:latest
           - "8000:80"
         restart: always
           WORDPRESS_DB_HOST: db:3306
           WORDPRESS_DB_USER: wordpress
           WORDPRESS_DB_PASSWORD: wordpress
           WORDPRESS_DB_NAME: wordpress
        db_data: {}

    How to manage multi-container application?

    To manage containers we can use a few basic docker-compose commands:

    • Build or rebuild services
    docker-compose build
    • Create and start containers
    docker-compose up

    The containers have been run and logs printed on the console. To run in background use parameter -d.

    • Run a one-off command on a service
    docker-compose run <service> <bash_command>
    ex: docker-compose run wordpress <service> <bash_command>

    For example, print Debian version of a WordPress container.

    • Show the list of containers running on a machine
    docker ps

    The above command presents the information about

    • container id,
    • image name and version,
    • how long ago the container was created,
    • status,
    • ports and container name.
    • Print list of information about running containers from current docker-compose.yaml
    docker-compose ps
    • Show all logs in container since its start
    docker logs <service>
    • Stop and remove containers, networks, volumes, and images created by the command “up”
    docker-compose down
    • Kill one or more running containers
    docker kill <container_id>
    • Show images list
    docker images
    • Execute a command in a running container
    docker exec <service> <bash_command>
    • Remove all unused data
    docker system prune

    Useful command combinations

    • Kill all run containers
    docker kill $(docker ps -q)
    • Stop all run containers
    docker stop $(docker ps -q)
    • Remove all images
    docker rmi $(docker images -q)
    • Remove all containers
    docker rm $(docker container ps -q)


    Docker-compose is a useful and easy tool to manage multiple containers. You can decide how containers are separated, what resources they can use, and how they communicate with each other. You can also set what should happen if the status of one of the containers changes. This feature allows you to restore the state of the system automatically.
