Question

我有一个简单的python程序，它执行以下操作

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：

#!/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

一个简单的网页应该返回＆＃39; hello docker＆＃39;由于某些原因，当我使用docker运行时不起作用。

我为运行应用程序提供的命令：

docker build -t identidock。

docker run -d -p 5000：5000 identidock

当我卷曲localhost：5000时，我收到以下消息

卷曲：（7）无法连接到localhost端口5000：拒绝连接

我是否知道我的泊坞窗配置是否存在问题？

我在MacOSX上使用以下docker版本

Docker版本17.03.1-ce，构建c6d412e

在泊坞广告ps -a上，容器状态显示＆＃39; UP＆＃39;

在docker日志CONTAINER_ID上，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。但是你没有在端口5000上运行任何东西，你在9090和9091上运行了一些东西。所以试试docker run -d -p 5000:9090 identidock或docker run -d -p 5000:9091 identidock

无法在docker上运行Web应用程序
