环境：python2.7   

docker:

一、一个简单的python程序

既然是一个简单的python程序，那我们就实现一个简单的加法功能即可。add.py,新建data文件夹

#coding=utf-8
import random
 
 
def add(aStr,bStr):
    map={}
    try:
        a=float(aStr)
        b=float(bStr)
        sum=a+b
        file_name=str(int(random.random()*1000000))+""
        file=open("data/"+file_name+'.txt',"w")
        file.write(str(a)+"+"+str(b)+"="+str(sum))
        file.close()
        map["result"]="OK"
        map["id"]=str(file_name)
    except:
        map["result"]="wrong"
 
 
 
 
    return map
 
 
if __name__=="__main__":
    print "运行run啊大哥，不是这个"
    map=add("4.5",5.6)
    print map

 

这个方法实现的功能都能看明白，就是把a和b相加，并且将结果输出在一个文件中，并返回是否运行成功，如果成功则再加上文件的编号（后面那段不管= =）

二、对外提供一个调用接口

除了这段代码我们还需要对外提供一个调用接口，我使用tornado开一个web服务来提供接口，这个方法命名为run方法= =

#coding=utf-8
 
import tornado.web
import tornado.ioloop
from add  import add
 
#定义处理类
class Add(tornado.web.RequestHandler):
    #添加一个post请求方式的方法
    def post(self):
        #向响应中，添加数据
        a=self.get_argument('a', '')
        b=self.get_argument('b', '')
        map=add(a,b)
        self.write(map)
 
def make_app():
    return tornado.web.Application(
        [(r'/add', Add)],
    )
 
if __name__ == '__main__':
    # 创建一个应用对象
    app = make_app()
    #绑定一个监听端口
    app.listen(8778)
    #启动web程序，开始监听端口的连接
    tornado.ioloop.IOLoop.current().start()

当我们运行run.py之后，在终端输入命令    curl  -d 'a=3&b=9' 'localhost:8778/add'

终端返回信息为:{"result": "OK", "id": "808992"}   （这里的ID不一定会相同，只是一个随机数)

在到同文件下面的data目录即可找到对应的数据文件

到此，我们已经实现了一个python的简单程序，并使其对外提供了一个接口调用，现在我们要将其打包到docker镜像中并对关键代码(add)进行加密

三、运行一个ubuntu镜像，对安装好python,vim等以及必要的python包例如tornado(docker 的安装使用就不多说了= =)

显然我们需要的是第一个镜像，将其pull到本地，即运行docker pull ubuntu

查看本地镜像docker images 可以看到刚才的镜像


启动它！并安装一些必要的东西！

docker run -it c9d990395902 /bin/bash   其中c9d990395902为ubuntu的镜像ID，如果你pull的时候它已经更新过了ID可能产生变化，/bin/bash是使得进入新运行的容器内部

首先执行apt update更新ubuntu系统

然后使用apt install python安装python2

中途会问你有一步是否继续，输入y并回车即可

输入python能进入如下页面即安装成功，输入exit()回车退出编辑

使用apt-get install python-pip python-dev build-essential安装pip，注意同样需要y回车

无法安装pip

apt-get install python-pip

修改为apt-get install python3-pip就可以............

使用pip3

python3

安装完成后输入pip -V即可查看是否安装成功

安装vim，命令是apt-get install vim

导入一些python的包，比如tornado，使用命令pip install tornado

再比如cython,命令为pip install cython

至此，我们给这个容器安装完成了python,pip,vim以及导入了两个必要的包

四、新建文件夹并且把代码复制到容器中

在根目录运行mkdir add_uncleyiba，新建文件夹add_uncleyiba

进入add_uncleyiba文件夹，新建目录data，新建文件test.py

用vim打开test.py

随便按个键比如a，进入编辑模式，输入print 123，然后按Esc，输入:wq（前面是冒号）,然后回车，即为保存

运行python test.py,测试一下没有问题

现在新建三个文件，分别叫add.py,run.py,setup.py

文件夹data也要..............

利用vim打开add.py把之前的代码复制进去，同理复制run.py的代码(注意，先进入编辑模式之后再复制）

复制并保存之后可以利用cat命令查看代码是否有问题

cat add.py

我们可以尝试在容器中运行add.py,使用命令python add.py

看上去也没有问题

现在vim打开setup.py文件，并输入以下内容

from distutils.core import setup
from Cython.Build import cythonize
 
setup(ext_modules = cythonize(["add.py"]))

 

然后保存退出

 

运行命令python setup.py build_ext，目的是为了生成add.py文件的so文件，保证源码安全

我们可以发现新生成了build文件夹

如图add.so即我们需要的so文件！

使用mv add.so ../../add.so将它放到外层的文件夹去

现在我们可以删除一些没有用的东西了，除了add.so,data,run.py,setup.py，其他的都可以删除了

友情提示：删除命令小心使用= =动图想必都看过了

图片好像动不起来- -可以去一些水群里面找图。。。

五、提交镜像，并运行测试

重新打开一个终端，然后将该容器制作成一个镜像docker commit 248224b7067e add_uncleyiba:1.0

 

 

id 是查看自己的容器id得到的，后面的是你要生成的镜像名字+冒号+版本号

之后我们查看本地镜像的时候就会发现成圣了add_uncleyiba:1.0这个镜像了

本机里的,回到一个任意目录，当然，最好是你之前保存python代码的目录，新建文件夹名字叫data

然后运行命令

docker run -itd -p 8899:8888  -v #{local_abs_path}:/add_uncleyiba/data  add_uncleyiba:1.0 python /add_uncleyiba/run.py

docker run -itd -p 8899:8778  -v/home/hlx2/wieghts/test/data:/add_uncleyiba/data  add_uncleyiba:1.0 python /add_uncleyiba/run.py

(base) root@NLP:/home/hlx2/wieghts/test# docker run -itd -p 8899:8778  -v/home/hlx2/wieghts/test/data:/add_uncleyiba/data  add_uncleyiba:1.0 python /add_uncleyiba/run.py

 

/home/hlx2/wieghts/test

其中#{local_abs_path}改成data文件夹的本地的绝对路径（cd进目录后使用pwd查看）

出现新的容器ID后使用curl  -d 'a=5&b=7' 'localhost:8888/add'进行访问测试就好了~

curl  -d 'a=5&b=7' 'localhost:8899/add'

(base) root@NLP:/home/hlx2/wieghts/test# curl  -d 'a=5&b=7' 'localhost:8899/add'

{"result": "wrong"}

 

 

(base) root@NLP:/home/hlx2/wieghts/test# curl  -d 'a=5&b=7' 'localhost:8899/add'

 

 

这时候我们可以进入到本地的data文件夹，会发现里面有一个文件名就是刚才返回的id值

打开即为我们刚才的测试内容

 

hlx2@NLP:~/wieghts/test$  curl  -d 'a=3&b=9' 'localhost:8778/add'
{"result": "wrong"}hlx2@NLP:~/wieghts/test$ curl
curl: try 'curl --help' or 'curl --manual' for more information
