Try docker-compose stop instead.

Is there any other solution for this? Maybe adding extra volume for Magento host data will solve the problem.

You must add volumes to the web service.

Edit the docker-compose.yml file as follows.

version: "3.0"
services:
  web:
    image: alexcheng/magento2
    ports:
      - "80:80"
    links:
      - db
    volumes:
      - web-file:/var/www
    env_file:
      - env
  db:
    image: mysql:5.7
    volumes:
      - db-data:/var/lib/mysql
    env_file:
      - env
  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    ports:
      - "8580:80"
    links:
      - db
volumes:
  db-data:
  web-file:

Unfortunetly, @osmansafak doesn't work. With your docker-compose config I can't even import data running install-sampledata command. It shows me some erros with authentication and so on :disappointed:.

I got the same problem.

And it's very strange. Using volumes actually intends to not have it, but... ((

I had a similar problem.

After running docker-compose up -d and docker exec -it <container-id> install-magento everything worked fine. As soon as I ran docker-compose down and started to re-run the containers, a database error occured (could not find table). I did solve it by adapting the db volume destination from db-data:/var/lib/mysql/data to db-data:/var/lib/mysql and adding external: true to both named volumes. Therefore I had to create them before running docker-compose up -d with the commands docker volume create --name=magento-data and docker volume create --name=db-data. I am using external: true mainly since I had some issues in the past whilst referencing named volumes when project names changed, it might be not critical to solve the issue above. For the sake of completeness, you find my docker-compose.yml below:

version: '3'
services:
  web:
    image: alexcheng/magento2
    ports:
      - "80:80"
    links:
      - db
    volumes: 
      - magento-data:/var/www/html  
    env_file:
      - env
  db:
    image: mysql:5.6.23
    volumes:
      - db-data:/var/lib/mysql
    env_file:
      - env
  phpmyadmin:
    image: phpmyadmin/phpmyadmin
    ports:
      - "8580:80"
    links:
      - db     
volumes:
  magento-data:
    external: true
  db-data:
    external: true

Maybe this helps anybody. If this is a common problem it might worth a pull request.

If you want to control where the data goes, an alternative is (at the end of docker-compose.yml):

volumes:
  magento-data:
  db-data: 
    driver: local
    driver_opts:
      type: 'none'
      o: 'bind'
      device: '/data/magento/db'

This is in addition to db-data:/var/lib/mysql
