【问题描述】：

我正在尝试使用 docker 将 api 挂载到 js 节点，一切正常，但不幸的是，当我对文件进行更改时，docker 不更新文件并且 nodemon 不更新服务器，这迫使我总是重启docker-compose up --build 命令。

我的树：

|- api
  |- src
    |- app.js
    |- index.js
    |- routes.js
  |- .dockerignore
  |- .editorconfig
  |- .env.example
  |- .package.json
|- app
|- docker-compose.yml

我的 docker-compose.yml ：

version: '3'

services:
  api:
    build: ./api
    command: npm run dev
    volumes:
      - ./api:/app
    ports:
      - 3001:3000
    restart: always
    environment:
      - "NODE_ENV=development"
  # front:
  #   build: ./front
  #   volumes:
  #     - ./front:/usr/src/app
  #   ports:
  #     - 3000:3000

我在 /api 中的 dockerfile ：

FROM node:10

# Create app directory
WORKDIR /usr/src/app

# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm@5+)
COPY package*.json ./

RUN npm install
# If you are building your code for production
# RUN npm install --only=production

# Bundle app source
COPY . .


EXPOSE 3000
CMD [ "npm", "run", "dev" ]

在我的终端中，nodemon 可以工作，但是当我进行修改时，没有任何动作：

docker-compose log picture

提前感谢您的帮助:)

【问题讨论】：

您要更改哪些文件以及如何更改它们？

我只是更改了 json 中的字符串（文件：routes.js），以便在邮递员上查看答案是否更改。

你解决了这个问题吗？

【参考方案1】：

您必须在脚本中添加 --watch。试试这个：

nodemon --watch src/index.js --exec \"node -r dotenv/config -r babel-register\""

查看documentation 的更多信息，查看监控多个目录部分。

【参考方案2】：

尝试使用-L 标志运行nodemon：nodemon -L app.js
