docker - 从主机映射卷更改时，容器文件未更新

Question

我有以下docker-compose.yml:

version: '3'

services:
  web:
    build: 
      context: .
      dockerfile: ./.docker/node.dockerfile
    volumes:
      - D:\Proj\Web:/app
    ports:
      - '3000:3000'
    depends_on: 
      - 'db'
    networks:
      - holder-network
    restart: on-failure
    tty: true


  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
    networks:
      - holder-network
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: P@ssw0rd
      MYSQL_DATABASE: holder_db
      MYSQL_USER: holder_usr
      MYSQL_PASSWORD: P@ssw0rd


networks:
  holder-network:
    driver: bridge

volumes:
  db_data:

和 node.dockerfile:

FROM node:7.10

RUN mkdir /var/www

RUN npm install nodemon -g

WORKDIR /var/www

ADD . /var/www

RUN npm install

CMD nodemon

我正在从主机更改 D:\Proj\Web下的文件，但是它不会更新容器中的文件。为什么？

Answer 1

我发现了错误。我的docker-compose.yml使用/app作为路径，而node.dockerfile使用/var/www。

这是更新(工作)的版本:

version: '3'

services:
  web:
    build: 
      context: .
      dockerfile: ./.docker/node.dockerfile
    volumes:
      - D:\Proj\Web:/var/www
    ports:
      - '3000:3000'
    depends_on: 
      - 'db'
    networks:
      - holder-network
    restart: on-failure
    tty: true


  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
    networks:
      - holder-network
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: P@ssw0rd
      MYSQL_DATABASE: holder_db
      MYSQL_USER: holder_usr
      MYSQL_PASSWORD: P@ssw0rd


networks:
  holder-network:
    driver: bridge

volumes:
  db_data:
