Docker: Mern 项目页面未加载

Question

我正在尝试运行使用 Docker 工具箱的 MERN 项目，因为我在 Windows 机器上，但我的项目没有运行。
这是我的项目文件夹结构：

 ├───api
 │   └───Dockerfile
 ├───ui
 │   └───Dockerfile
 ├───docker-compose.yml

docker-compose.yml

 version: '2'
 services:
   ui:
     build: ./ui
     ports:
       - '3000:3000'
     depends_on:
       - api
     #command: tail -f /dev/null
   api:
     build: ./api
     ports:
       - '8080:8080'
     depends_on:
       - mongo
   mongo:
     image: mongo
     ports:
       - '27017:27017'

./ui/Dockerfile

 FROM node:8
 # Create app directory
 WORKDIR /usr/src/app
 # Install app dependencies
 COPY package*.json ./

 RUN npm install
 # Copy app source code
 COPY . .

 #Expose port and start application
 EXPOSE 3000
 CMD ["npm", "start"]

./api/Dockerfile

 FROM node:8
 # Create app directory
 WORKDIR /usr/src/app
 # Install app dependencies
 COPY package*.json ./

 RUN npm install
 # Copy app source code
 COPY . .

 #Expose port and start application
 EXPOSE 8080
 CMD [ "npm", "start" ]

当我从根目录运行 docker-compose up --build 时，一切似乎都可以正确编译，但它会以 express-mongo-docker-tutorial_ui_1 exited with code 0

退出

docker-machine ip default 打印出 192.168.99.101 所以我转到 192.168.99.101:3000 但我的页面没有加载

如果我这样做 docker ps 我明白了

 CONTAINER ID        IMAGE                               COMMAND                  CREATED             STATUS              PORTS                      NAMES
 fd90ffb3323f        express-mongo-docker-tutorial_api   "docker-entrypoint.s…"   22 minutes ago      Up 22 minutes       0.0.0.0:8080->8080/tcp     express-mongo-docker-tutorial_api_1
 5ed2d070b45f        mongo                               "docker-entrypoint.s…"   22 minutes ago      Up 22 minutes       0.0.0.0:27017->27017/tcp   express-mongo-docker-tutorial_mongo_1

我尝试了将 command: tail -f /dev/null 添加到我的 docker-compose.yml 文件的解决方案，我确实看到了容器

 CONTAINER ID        IMAGE                               COMMAND                  CREATED             STATUS              PORTS                      NAMES

但是当我转到 192.168.99.101:3000 时，我的页面仍然无法加载。我做错了什么？

Answer 1

我想出来了，我所要做的就是在我的 docker-compose.yml

中添加 tty:true

 ui:
  build: ./ui
  ports:
    - '3000:3000'
  depends_on:
    - api
  tty:true #<-----
