Docker-compose: docker卷中不存在node_modules

Question

我正在使用docker-compose来安装和启动应用程序。但在这里，应用程序无法使用node_modules来运行它。我已经检查了这个Docker-compose: node_modules not present in a volume after npm install succeeds，但它对我没有帮助。

这是我的docker-compose.yml

version: "2"

services:
    neo4j:
        container_name: ms_neo4j
        image: neo4j:latest
        environment:
            - NEO4J_AUTH=none
        ports:
            - "7474:7474"
            - "7687:7687"

        links:
            - "mongo:mongo"
        volumes:
            - "./petstore:/src/app"
            - node_modules:/petstore/node_modules
        working_dir: "/src/app"
        ports:
            - "8080:8080"
            - "5858:5858"
        # command: npm run start
        command: npm run start:dev

    users:
        build: ./users
        container_name: ms_users
        links:
            - neo4j
        volumes:
            - "./users:/src/app"
            - node_modules:/users/node_modules
        working_dir: "/src/app"
        command: npm start

volumes:
    node_modules:

有谁知道如何解决这个问题吗？

我注意到与文件中的路径相关的一些事情看起来很可疑：

在docker-compose文件中，您使用/src/app作为工作目录，但在docker文件中，您使用的是/usr/src/app

Fix:在两个文件中使用相同的工作目录，从您的docker-compose文件中完全省略working_dir，并修复您的docker-compose文件中的路径。通过使用WORKDIR命令，您的Dockerfile可以简化为

FROM node:latest

RUN npm i -g rimraf typescript

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
# notice how I am omitting the /usr/src/app since you already have declared it as the workdir and just copying into the current directory `.`
COPY package.json .
RUN npm install
COPY . .

您的docker-compose文件应该像这样反映这些路径更改：

    petstore:
        build: ./petstore
        container_name: ms_petstore
        environment:
            - loglevel=none
        links:
            - "mongo:mongo"
        volumes:
            - "./petstore:/usr/src/app"
            - ./node_modules:/usr/src/app/node_modules
        ports:
            - "8080:8080"
            - "5858:5858"
        # command: npm run start
        command: npm run start:dev
