删除node14
#ansible-playbook r.move.node14.yml -k \
-e docker_bin_dir=”/usr/bin” \
-e kube_network_plugin=”calico-rr”
#kubectl delete node node14
#kubectl get nodes node14就删除完毕
增加node14
在hosts.ini的nodes部分加上node别名即可，当然的提前ssh-key打通
ansible-playbook -i inventory/sk/hosts.ini scale.yml -b -k
root@node10:~# kubectl get nodes
