无法在Docker上运行Web应用程序
我有一个简单的Python程序，执行以下操作
identitydock.py
from flask import Flask app = Flask(__name__) @app.route('/') def hello_world(): return 'Hello Docker!\n' if __name__ == '__main__': app.run(debug=True, host='0.0.0.0') 我的Dockerfile如下
Dockerfile
FROM python:3.4 RUN groupadd -r uwsgi && useradd -r -g uwsgi uwsgi RUN pip install Flask==0.10.1 uWSGI==2.0.8 WORKDIR /app COPY app /app COPY cmd.sh / EXPOSE 9090 9191 USER uwsgi CMD ["/cmd.sh"]
我的cmd.sh如下所示：
#!/bin/bash set -e if [ "$ENV" = 'DEV' ]; then echo "Running Development Server" exec python "identidock.py" else echo "Running Production Server" exec uwsgi --http 0.0.0.0:9090 --wsgi-file /app/identidock.py \ --callable app --stats 0.0.0.0:9191 fi
由于某种原因，应该返回“hello docker”的简单网页在我使用docker运行时不起作用。
我给运行该应用程序的命令：
dockerbuild设-t identidock。
docker运行-d -p 5000：5000 identidock
当我curl本地主机：5000我收到以下消息
curl：（7）无法连接到本地端口5000：连接被拒绝
我可以知道，如果我的dockerconfiguration有问题吗？
我在MacOSX上使用以下docker版本
Docker版本17.03.1-ce，构buildc6d412e
参考源https://github.com/using-docker/using_docker_in_dev
编辑-1
在docker ps -a上，容器状态显示“UP”
在docker日志CONTAINER_ID，我得到以下日志

您将主机上的端口5000连接到容器上的端口5000。 但是你没有在5000端口上运行任何东西，你有东西在9090和9091上运行。所以试试docker run -d -p 5000:9090 identidock或docker run -d -p 5000:9090 identidock docker run -d -p 5000:9091 identidock
