准备

1).修改配置文件

修改机器名和IP ./hosts

修改k8s集群配置 ./coreos/group_vars/coreos

2). 准备HTTP_SERVER

http://172.16.11.235/k8s 确保http服务器上有以下文件：

etcd-v3.2.11.tgz
flannel-v0.9.1.tgz
hyperkube-v1.9.0.tgz
kubectl-v1.9.0.tgz
registry-2.6.2.tgz
registry-data-v1.9.0.tgz

-h ansible `
-v c:/git/github.com/ansible/:/etc/ansible `
-d hub.c.163.com/mengkzhaoyun/public:ansible-2.3.0-centos7 /bin/sh -c "while true; do echo hello world; sleep 1; done"

2).in ansible docker bash

# 进入容器
docker exec -it ansible bash

# 执行命令在coreos上安装k8s集群
cd coreos
ap a.bootstrap.yml
ap b.install.yml
ap c.test.yml

3).check
