与Angular 4和Django的Docker编译成功，但localhost：4200不能正常工作
我想用Django后端和postgresql数据库dockerize Angular 4前端。 在这一刻我的文件如下所示。 我记得确定这是否正确完成？ 当我尝试docker-compose up我得到了Angular 4前端和Django后端都成功启动的信息。 不幸的是，当我打开http：// localhost：4200它不起作用（localhost：8001似乎工作）：

来自前端的Dockerfile ：
# Create image based on the official Node 6 image from dockerhub FROM node:6 # Create a directory where our app will be placed RUN mkdir -p /usr/src/app # Change directory so that our commands run inside this new directory WORKDIR /usr/src/app # Copy dependency definitions COPY package.json /usr/src/app # Install dependecies RUN npm install # Get all the code needed to run the app COPY . /usr/src/app # Expose the port the app runs in EXPOSE 4200 # Serve the app CMD ["npm", "start"]
主目录下的Dockerfile ：
FROM python:3.6.1 ENV PYTHONUNBUFFERED 1 RUN mkdir /code WORKDIR /code ADD requirements.txt /code/ RUN pip3 install -r requirements.txt ADD . /code/
docker-compose.yml ：
version: '3' services: db: image: postgres environment: POSTGRES_USER: aso POSTGRES_PASSWORD: somepass django: build: . command: python3 MainDirectory/backend/myProject/manage.py runserver 0.0.0.0:8001 volumes: - .:/code ports: - "8001:8001" depends_on: - db angular: build: MainDirectory/frontend ports: - "4200:4200" depends_on: - django
服务器在端口4200上运行，但是您在8010上暴露了80端口：
angular: build: MainDirectory/frontend ports: - "8010:80" # <==== HERE depends_on: - django
你应该可以使用：
angular: build: MainDirectory/frontend ports: - "4200:4200" depends_on: - django
您可能还必须让您的服务器（ npm start脚本）绑定到0.0.0.0 。
