将Python解释器设置为Docker

Question

我已经设置了一个PythonFlask项目，指向运行在Docker中的解释器：

从PyCharm IDE启动Flask应用程序将产生以下输出：

51be5e336622:python3 -u /opt/project/app.py
Starting server
 * Serving Flask app "app" (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: on
 * Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
 * Restarting with stat
Starting server
 * Debugger is active!
 * Debugger PIN: 328-461-278

试图打开http://localhost:5000/ 导致页面未找到错误。

如果我使用Docker与Dockerfile运行应用程序：

FROM python:3.8-slim-buster

WORKDIR /app

COPY requirements.txt requirements.txt

RUN pip3 install -r requirements.txt

COPY . .

EXPOSE 5000

#CMD [ "python3", "-m" , "flask", "run", "--host=0.0.0.0"]

CMD [ "python3", "-u" , "/app/app.py"]

上述Dockerfile构建PyCharm连接的容器，并在PyCharm中配置为：

使用命令Docker run-p 5000:5000 services运行Docker容器，应用程序在上启动http://localhost:5000/ 成功地

我是否需要将端口5000从PyCharm IDE映射到在端口5000上运行的Docker容器？如何实现这一点，PyIDE中似乎没有一个选项？




Answer 1

在https://blog.jetbrains.com/pycharm/2017/03/docker-compose-getting-flask-up-and-running/的帮助下，这正在发挥作用。

Dockerfile：

FROM python:3.8-slim-buster

WORKDIR /app

COPY requirements.txt requirements.txt

RUN pip3 install -r requirements.txt

COPY . .

EXPOSE 5000

CMD [ "python3", "-m" , "flask", "run", "--host=0.0.0.0"]

app.py主要方法：

if __name__ == '__main__':

    for handler in logging.root.handlers[:]:
        logging.root.removeHandler(handler)

    logging.basicConfig(level=logging.INFO,
                        filename='./logs/' + str(
                            int(round(time.time() * 1000))) +'trade.log',
                        filemode="a+",
                        format="%(asctime)-15s %(levelname)-8s %(message)s",
                        datefmt='%Y-%m-%d %H:%M:%S')
    logging.getLogger().addHandler(logging.StreamHandler(sys.stdout))

    print('Starting server')
    app.run(host="0.0.0.0", port=5000, debug=True)

docker-compose.yml，注意端口5000的使用：

version: '2'
services:
  web:
    build: .
    ports:
      - "5000:5000"
    volumes:
      - .:/app

开始docker撰写：

docker-compose up

更新PyCharm以使用docker comment实例：

app.py中执行main的输出：
