docker-compose中的卷在Windows 7上不起作用

Question

Here's a sample docker-compose.yml file.

version: '3'
services:
  app:
    build:
      context: .
      dockerfile: docker/Dockerfile
    image: docker-test
    container_name: docker-test
    ports:
      - 80:80
    volumes:
      - .:/srv/app

Here's the Dockerfile

FROM php:7.3-apache-stretch

COPY . /srv/app
COPY docker/vhost.conf /etc/apache2/sites-available/000-default.conf

RUN chown -R www-data:www-data /srv/app \
    && a2enmod rewrite

There are no errors in running this except file changes in . are not reflected in realtime inside the container /src/app . Any ideas what's wrong with it?

For those who care, apparently the default setup in Docker Toolbox for Windows 7 doesn't read outside C:/Users so you have to manually setup the shared folders in VirtualBox. This article helped me.

Once you set that up, your docker-compose.yml file needs to be like this:

volumes:
  - <shared-folder>:/srv/app

Replace <shared-folder> with the name of the shared folder in VirtualBox.
