How to mount folder with files in docker?

Question

Docker

Hello, I'm learning docker.
I work on macos.
Installed https://docs.docker.com/toolbox/toolbox_install_mac/ they say it works faster through it.
wrote config:

version: '2'

services:
  php:
    build: ./docker/php/
    container_name: php
    volumes_from:
      - source
    ports:

    links:
      - mysql
      - memcached
    networks:
      - bitrix

    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: 10.100.0.0/24

Bitrix site.
after the command
docker-compose up -d --build
everything started:

Creating source ... done
Creating mysql     ... done
Creating memcached ... done
Creating php       ... done
Creating webserver ... done

but when I type my domain in the browser (which I registered in nginx, hosts), I get the answer "Unable to access the site"
I decided to go into the container itself and see what's there, through the command:
docker exec -it webserver bash
I went in, I see my nginx configs, go to the folder where the files should be, but it’s empty there, they didn’t mount, .. there is my /var/www/bitrix folder, but it’s empty, hence the error in the browser, tell me what’s the matter?

Answer 1

You need to share the disk where the directory is mounted. This was a problem on Windows, I think for poppy you also need to share folders

Answer 2

web_server:
    build: ./docker/nginx/
    container_name: webserver
    volumes:
      - ./my/volume:/container/volume
