kubernetes忘记token怎么加入k8s集群

 

1.生成一条永久有效的token

kubeadm token create --ttl 0

# kubeadm token list
TOKEN                     TTL         EXPIRES                     USAGES                   DESCRIPTION   EXTRA GROUPS
dxnj79.rnj561a137ri76ym   <invalid>   2018-11-02T14:06:43+08:00   authentication,signing   <none>        system:bootstrappers:kubeadm:default-node-token
o4avtg.65ji6b778nyacw68   <forever>   <never>                     authentication,signing   <none>        system:bootstrappers:kubeadm:default-node-token

2.获取ca证书sha256编码hash值

openssl x509 -pubkey -in /etc/kubernetes/pki/ca.crt | openssl rsa -pubin -outform der 2>/dev/null | openssl dgst -sha256 -hex | sed 's/^.* //'

3.node节点加入

kubeadm join 10.167.11.153:6443 --token o4avtg.65ji6b778nyacw68 --discovery-token-ca-cert-hash sha256:2cc3029123db737f234186636330e87b5510c173c669f513a9c0e0da395515b0
