1.  创建一个docker镜像

<table style="margin-left:18pt;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:414.8pt;"> # 先创建一个文件夹 mkdir docker_test # 创建一个脚本 vim myhttp.py 
 <div> 
 # coding:utf-8 
 import json 
 from urlparse import parse_qs 
 from wsgiref.simple_server import make_server 
 &nbsp; 
 &nbsp; 
 def application(environ, start_response): 
 &nbsp;&nbsp;&nbsp; start_response('200 OK', [('Content-Type', 'text/html')]) 
 &nbsp;&nbsp;&nbsp; params = parse_qs(environ['QUERY_STRING']) 
 &nbsp;&nbsp;&nbsp; name = params['name'][0]&nbsp;&nbsp;&nbsp; 
 &nbsp;&nbsp;&nbsp; return [json.dumps('you input '+name)]&nbsp;&nbsp; 
 &nbsp; 
 if __name__ == "__main__": 
 &nbsp;&nbsp;&nbsp; port=8000 
 &nbsp;&nbsp;&nbsp; httpd = make_server("0.0.0.0", port, application) 
 &nbsp;&nbsp;&nbsp; print ("serving http on port {0}...".format(str(port))) 
 &nbsp;&nbsp;&nbsp; httpd.serve_forever() 
 </div> # python2 myhttp.py 
 <div> 
 # 在浏览器运行 <a href="http://IP:8000/?name=123" rel="nofollow">http://IP:8000/?name=123</a> 
 </div> # 创建一个镜像 vim Dockerfile 
 <div> 
 FROM python:2 
 MAINTAINER zc 
 ADD myhttp.py myhttp_docker.py 
 EXPOSE 8001 
 ENTRYPOINT ["python2","myhttp_docker.py"] 
 </div> # 打镜像 docker build -t image01 . <img alt="" height="189" src="https://img-blog.csdnimg.cn/20201114110724550.png" width="822"> </td> 
 </tr>
