kubernets添加节点

首先在master上生成加入命令

# kubeadm token create --print-join-command

添加新node

# kubeadm join 192.168.223.158:16443 --token j97y95.yso1taprzg8ulwx7 --discovery-token-ca-cert-hash sha256:b5c4bda4ea84ca50ab41e325126101f78962459523fc760feaff4420871ea059 

添加新master，需拷贝相关证书至新节点/etc/kubernets下的ca.*,sa.*,front-proxy-ca.*,admin.conf

# kubeadm join 192.168.223.158:16443 --token j97y95.yso1taprzg8ulwx7 --discovery-token-ca-cert-hash sha256:b5c4bda4ea84ca50ab41e325126101f78962459523fc760feaff4420871ea059  --control-plane
