3). SSH

Store Ansible SSH Key on each CentOS Server

Install

1).run ansible from docker

docker run `
--name ansible `
-h ansible `
-v c:/git/mengkzhaoyun/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).enter in ansible cotainer , install etcd ..

# enter contianer run ansible scripts
docker exec -it ansible bash

# check ssh link
ssh 172.16.11.247
ssh 172.16.11.248
ssh 172.16.11.249

# exec commands to install k8s 
cd linux
ap 1.install-centos.yml -i centos

3).check rkt & etcd

# ssh 172.16.11.248
