k8s客户端探索

先推荐几个网站http://docs.kubernetes.org.cn/29.html，kubernetes中文文档https://kubernetes.io/zh/官网

https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.13/#-strong-write-operations-cronjob-v1beta1-batch-strong-

专门讲api的网址

领导要求能否程序化的启动一个docker,按照给定的参数（主要是运行策略so），运行，并且能够控制这个容器的cpu和内存，并且超过上限cpu和内存等待不能退出，停止，并且获取docker的状态，

想了想大概就是模仿客户端创建一个pod,pod里面运行一个容器吧，公司都是c++,

由于目前还算会点python ,先看python的取点经验

官方python的client https://github.com/kubernetes-client/python

报错解决https://github.com/kubernetes-client/python/issues/551

yum install git

git clone --recursive https://github.com/kubernetes-client/python.git

升级setuptools

pip install --upgrade setuptools

[root@kube_node_134 pip-1.5.4]# easy_install --version

pip install websocket-client

yum install telnet

yum install telnet-server
