How to mount volume in docker compose version '2' format

So I have a trouble with mount new format version 2 docker compose file. I have the code in folder wordpress inside where is location docker-compose file also I have inside the folder code docker file like this:

FROM debian:jessie
VOLUME /var/www/wordpress

When I used old format like this:

application:
    build: code
    volumes:
        - ./wordpress:/var/www/wordpress
        - ./logs/wordpress:/var/www/wordpress/app/logs
    tty: true
db:
    image: mysql
    ports:
        - 3306:3306
    environment:
        MYSQL_ROOT_PASSWORD: root
        MYSQL_DATABASE: somename
        MYSQL_USER: root
        MYSQL_PASSWORD: root
php:
    build: php-fpm
    ports:
        - 9001:9001
    volumes_from:
        - application
    links:
        - db
nginx:
    build: nginx
    ports:
        - 8080:80
    links:
        - php
    volumes_from:
        - application
    volumes:
        - ./logs/nginx/:/var/log/nginx
elk:
    image: willdurand/elk
    ports:
        - 81:80
    volumes:
        - ./elk/logstash:/etc/logstash
        - ./elk/logstash/patterns:/opt/logstash/patterns
    volumes_from:
        - application
        - php
        - nginx

When I started use version '2' the same as code as previous version I got any error so I reformat my compose file and move dockerfile from code folder to insider main folder where is location docker-compose file. My new version docker-compose became looks like as:

version: '2'
services:
  web:
    build: .
    volumes:
     - /wordpress:/var/www/wordpress
     - /logs/wordpress:/var/www/wordpress/app/logs
    tty: true

  db:
      image: mysql
      ports:
          - 3306:3306
      environment:
          MYSQL_ROOT_PASSWORD: root
          MYSQL_DATABASE: somename
          MYSQL_USER: root
          MYSQL_PASSWORD: root
  php:
      build: php-fpm
      ports:
          - 9001:9001
      volumes_from:
          - web
      links:
          - db
  nginx:
      build: nginx
      ports:
          - 82:82
      links:
          - php
      volumes_from:
          - web
      volumes:
          - /logs/nginx/:/var/log/nginx
  elk:
      image: willdurand/elk
      ports:
          - 81:80
      volumes:
          - /elk/logstash:/etc/logstash
          - /elk/logstash/patterns:/opt/logstash/patterns
      volumes_from:
          - web
          - php
          - nginx

Finally after reformat the code docker-compose was successfully build and up but when I open my php and nginx container inside both of them in /var/www/worpdress I have just empty folder app is not my wordpress project. In which place I was mistake with settings mount project volume? Thanks in advance.

The problem is with the way you are defining the local directories to be used for the volumes. In your previous version, you were using ./wordpress, while in the new one, you're using just /wordpress.

When referencing local directories for volume mappings, they always have to start with ./ - please try this:

version: '2'
services:
  web:
    build: .
    volumes:
      - ./wordpress:/var/www/wordpress
      - ./logs/wordpress:/var/www/wordpress/app/logs

One more thing: I recommend to always enclose the volume mappings in double quotes to avoid issues with space characters, e.g.:

version: '2'
services:
  web:
    build: .
    volumes:
      - "./wordpress:/var/www/wordpress"
      - "./logs/wordpress:/var/www/wordpress/app/logs"
