// 这个命令将在你的容器中运行whalesay镜像
docker run docker/whalesay cowsay boo

// 本地系统中有哪些景象
docker images

// 运行自己的东西
docker run docker/whalesay cowsay xyz

//当前目录下的Dockerfile来创建一个叫做docker-whale的镜像
docker build -t docker-whale .

Dockerfile 内容

# Use an official Python runtime as a parent image
FROM python:2.7-slim

# Set the working directory to /app
WORKDIR /app

# Copy the current directory contents into the container at /app
COPY . /app

# Install any needed packages specified in requirements.txt
RUN pip install --trusted-host pypi.python.org -r requirements.txt

# Make port 80 available to the world outside this container
EXPOSE 80

# Define environment variable
ENV NAME World

# Run app.py when the container launches
CMD ["python", "app.py"]

requirement.txt 内容

Flask
Redis

app.py内容
from flask import Flask
from redis import Redis, RedisError
import os
import socket

# Connect to Redis
redis = Redis(host="redis", db=0, socket_connect_timeout=2, socket_timeout=2)

app = Flask(__name__)

@app.route("/")
def hello():
    try:
        visits = redis.incr("counter")
    except RedisError:
        visits = "<i>cannot connect to Redis, counter disabled</i>"

    html = "<h3>Hello {name}!</h3>" \
           "<b>Hostname:</b> {hostname}<br/>" \
           "<b>Visits:</b> {visits}"
    return html.format(name=os.getenv("NAME", "world"), hostname=socket.gethostname(), visits=visits)

if __name__ == "__main__":
    app.run(debug=True, host='0.0.0.0', port=80)

下面是个人的操作，WIn10电脑
基于上面的Dockerfile requirements.txt app.py, 这三个文件, 都是刚在testA文件夹下
cd testA
docker build -t dockertest2 .　// 创建dockertest2

docker run -p 4000:80 dockertest2 // 运行dockertest2
