        ports:
            - "9201:9200"
    phpmyadmin:
        restart: always
        image: phpmyadmin/phpmyadmin
        depends_on:
        - mysql
        ports:
        - "6080:8080"
    composer:
        image: composer:1.6
        volumes:
          - ./:/var/www
        working_dir: /var/www
        command: composer install

project on localhost:8080 works fine.
But phpmyadmin on localhost:6080 does not open. What could be the problem ?

docker logs ContainerName will give more information why the container didn't start
