验证

利用docker跑服务端和客户端
helloworld程序是github grpc里的示例文件，下载目录：https://github.com/grpc/grpc/tree/master/examples/python/helloworld

1. 服务端启动

$ docker ps | grep ubuntu
be6f5b966749        ubuntu           "/bin/sh -c /bin/bash"   2 hours ago         Up 2 hours                              dazzling_margulis
$ docker exec -it be6f5b966749  sh

helloworld# ls
greeter_client.py   greeter_server.py  
helloworld# python3 greeter_server.py

2. 客户端启动

$ docker ps | grep ubuntu
be6f5b966749        ubuntu            "/bin/sh -c /bin/bash"   2 hours ago         Up 2 hours                              dazzling_margulis
$ docker exec -it be6f5b966749  sh

helloworld# ls
greeter_client.py   greeter_server.py  
# python3 greeter_client.py
Greeter client received: Hello, you!         <<<< 通信成功！
