docker - docker simple index.html下运行vue/cli app打开

Question

我想在 docker 下安装我的 @vue/cli 4.0.5 应用程序，我找到了这个包
https://hub.docker.com/r/ebiven/vue-cli
假设这是我需要的(？)我修改了 _Docker/docker-compose.yml

web:
    container_name: vtasks_web

    build:
        context: ./web
        dockerfile: Dockerfile.yml

    environment:
        - APACHE_RUN_USER=www-data
    volumes:
        - ${APP_PATH_HOST}:${APP_PTH_CONTAINER}
    ports:
        - 8088:80
    working_dir: ${APP_PTH_CONTAINER}

...

vue_cli:
    container_name: vtasks_vue_cli
    image: ebiven/vue-cli:latest
    volumes:
        - ${APP_PATH_HOST}:${APP_PTH_CONTAINER}
    working_dir: ${APP_PTH_CONTAINER}
    command: npm install

构建应用程序和下一个检查日志我没有错误，还创建了 node_modules(我之前删除了它):

但进入灌木丛我跑

npm run serve

命令，它显示:

ONE  Compiled successfully in 10065ms                                                                                                                                                                                            4:21:52 PM


  App running at:
  - Local:   http://localhost:8080/ 

  It seems you are running Vue CLI inside a container.
  Access the dev server via http://localhost:<your container's external mapped port>/

  Note that the development build is not optimized.
  To create a production build, run npm run build.

所以我跑

http://localhost:8088/

在网络容器中，我设置了 8088:80
但是在浏览器中，我看到 index.html 已打开(按标题和页面内容)但未呈现 js？

什么是有效方式？

修改 block :
查看演示 https://github.com/ebiven/docker-vue-cli我看到
ebiven/docker-vue-cli 用作 Web 容器，因此删除 node_modules 目录并重新制作了我的 _Docker/docker-compose.yml :

version: '3.5'

services:



    web:
        container_name: vtasks_web

        image: ebiven/vue-cli

        command: npm install
#        command: npm install ; npm run serve  // I GOT ERROR HERE
#        command: npm run serve

        build:
            context: ./web
            dockerfile: Dockerfile.yml

        environment:
            - APACHE_RUN_USER=www-data

        volumes:
            - ${APP_PATH_HOST}:${APP_PTH_CONTAINER}
        ports:
            - "8088:80"

        working_dir: ${APP_PTH_CONTAINER}


    db:
        container_name: vtasks_db
        image: mysql:5.7.28
        restart: always
        environment:
            - MYSQL_DATABASE=DockerVTasks
            - MYSQL_USER=docker_user
            - MYSQL_PASSWORD=4321
            - MYSQL_ALLOW_EMPTY_PASSWORD=false
            - MYSQL_ROOT_PASSWORD=321
            - TZ=Europe/Kiev

        volumes:
            - ${DB_PATH_HOST}:/var/lib/mysql


    adminer:
      container_name: vtasks_adminer
      image: adminer
      restart: always
      ports:
        - 8089:8080
      links:
        - db

结果我看到:

我看到 node_modules 目录已生成，但我还需要运行

npm run serve

后

npm install

修改 block ＃2:

修改命令为

command: bash -c "npm install && npm run serve"

我得到了下一个没有错误的输出:

但是我要运行哪个网址？
在

我得到错误:

我试图为格式设置一些代码:
但我不确定他们叫什么:

?

但是我应该使用哪种语法？

修改 block #3

运行

http://localhost:8080/ 

在我的浏览器中出现错误:

但是在我的 _Docker/docker-compose.yml 我有选项:

您需要为 node_modules 创建一个“命名卷”。目录和 dist目录，这样这些目录就不会被您的绑定(bind)挂载覆盖(这个东西:${APP_PATH_HOST}:${APP_PTH_CONTAINER})。

This教程解释得更好:

The second is a named volume, node_modules. When Docker runs the npm install instruction listed in the application Dockerfile, npm will create a new node_modules directory on the container that includes the packages required to run the application. The bind mount we just created will hide this newly created node_modules directory, however. Since node_modules on the host is empty, the bind will map an empty directory to the container, overriding the new node_modules directory and preventing our application from starting. The named node_modules volume solves this problem by persisting the contents of the /home/node/app/node_modules directory and mounting it to the container, hiding the bind.

为此，您可以在 web 下添加两个新卷。服务并将它们添加到 volumes 下在您的 docker-compose.yml 底部也:

web:
    volumes:
        - ${APP_PATH_HOST}:${APP_PTH_CONTAINER}
        - node_modules:${APP_PTH_CONTAINER}/node_modules
        - dist:${APP_PTH_CONTAINER}/dist

volumes:
  node_modules:
  dist:

我让 VueCLI 在 Docker 中使用以下文件:
Dockerfile :

FROM node:lts-alpine

# install simple http server for serving static content
RUN npm install --quiet -g http-server

# install the vue-cli
RUN npm install --quiet --global \
      @vue/cli

# create app directory
RUN mkdir /app

# copy both 'package.json' and 'package-lock.json' (if available)
COPY package*.json /app/

# copy project files and folders to the current working directory (i.e. 'app' folder)
COPY . /app/

# make the 'app' folder the current working directory
WORKDIR /app

# install project dependencies
RUN npm install

# build the app
RUN npm run build

docker-compose.yml :

version: '3'

services:
  web:
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - .:/app
      - node_modules:/app/node_modules
      - dist:/app/dist
    ports:
      - "8080:8080"
    # uncomment command below to run development version
    # command: "npm run serve"
    command: "http-server dist"

volumes:
  node_modules:
  dist:

我跑了 docker-compose up然后我的应用程序在 http://localhost:8080/ 可用.

更新您的 Dockerfile 后第一次，一定要重建容器，例如 docker-compose up --build .
