Cannot docker-compose up with composer container

[nyonor]

Hi! This is My docker-compose.yml:

version:  '2'

volumes:
  database_data:
    driver: local

services:
  nginx:
    image: nginx:latest
    ports:
      - 8080:80
    volumes:
      - ./docker/nginx/default.conf:/etc/nginx/conf.d/default.conf
    volumes_from:
      - php

  php:
    build: ./docker/php/
    expose:
      - 9000
    volumes:
      - .:/var/www/html
    environment:
      XDEBUG_CONFIG: remote_host=192.168.1.40
      PHP_IDE_CONFIG: "serverName=nginx.local"

  mysql:
    image: mysql:latest
    command: --disable-partition-engine-check
    ports:
      - 3306:3306
    expose:
      - 3306
    environment:
      MYSQL_ROOT_PASSWORD: blablabla
      MYSQL_DATABASE: blablabla_db
      MYSQL_USER: blablabla
      MYSQL_PASSWORD: blablabla
    volumes:
        - database_data:/var/lib/mysql

  composer:
    build: ./docker/composer/
    volumes:
      - .:/app

This is the Dockerfile inside ./docker/composer/

        exit(1); \
    }" \
 && php /tmp/installer.php --no-ansi --install-dir=/usr/bin --filename=composer --version=${COMPOSER_VERSION} \
 && composer --ansi --version --no-interaction \
 && rm -rf /tmp/* /tmp/.htaccess

COPY docker-entrypoint.sh /docker-entrypoint.sh

WORKDIR /app

ENTRYPOINT ["/docker-entrypoint.sh"]

CMD ["composer"]

And i did create the docker-entrypoint.sh inside same directory.

Trying to docker-compose up...
The result is:

Somebody can tell me why? Thx!

The composer image is for running commands only. It is not a container that runs a service or anything.

[nyonor]

So if i want convinient deployment with docker-compose up then it is impossible?
For example - designer pulling the repo of project, than trying to deploy it on local machine to do some job he will be faced with obstacles...

[alcohol]

No, I don't see why that should be the case. Are you new to docker-compose ?

[nyonor]

Yes i am =)

[alcohol]

docker-compose is more for managing your services. Installing dependencies is a build step. But, you can make a docker-compose step for this if you really want to.

  composer:
    image: composer:latest
    volumes:
      - .:/app
    command: 'true'

And then you could:

docker-compose run composer install

And when you run docker-compose up -d the composer service will just do nothing.

Thank you
