/root/.ssh/authorized_keys

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAAAgQDCJNFRbNc0SsHa/+mWB71z7SLPH9rQpwEqGbRo7q466a97h3bejNav9wc9AKmepHPfRw7DJfSmWO3lGBya0QkXMYXVvtfcWPvZZDlar5JK/ZsC8HGOpwVLdd1uUfyPu2qM0sjRNA/Ty8PDMkS5dSyZAJNlxUAILRpepkYoT8jhrw== ansible@space.docker

define the cluster in hosts

  • systech14
  • systech15
  • systech16

./hosts

[systech]
systech14 ansible_ssh_host=172.16.11.244 ansible_ssh_port=22 ansible_ssh_user=root 
systech15 ansible_ssh_host=172.16.11.245 ansible_ssh_port=22 ansible_ssh_user=root 
systech16 ansible_ssh_host=172.16.11.246 ansible_ssh_port=22 ansible_ssh_user=root 
; systech17 ansible_ssh_host=172.16.11.247 ansible_ssh_port=22 ansible_ssh_user=root  
; systech18 ansible_ssh_host=172.16.11.248 ansible_ssh_port=22 ansible_ssh_user=root 
; systech19 ansible_ssh_host=172.16.11.249 ansible_ssh_port=22 ansible_ssh_user=root

# etcd options
ETCD_CLUSTER_ROLE: 
  systech14: etcd

# k8s option
K8S_CLUSTER_ROLE: 
  systech14: master

K8S_MASTER_IP: "{{ hostvars['systech14']['ansible_default_ipv4']['address'] }}"
