# kubeadm添加一个新的节点
|

|
|
|

首先获取证书的hash值， 这个值用于 `--discovery-token-ca-cert-hash`
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
HASH=$(openssl x509 -pubkey -in /etc/kubernetes/pki/ca.crt | openssl rsa -pubin -outform der 2>/dev/null | openssl dgst -sha256 -hex | sed 's/^.* //')
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
获取token, 这个值用于 `--token`
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
kubeadm token list
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
如果没有任何token列出，创建一个
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
TOKEN=$(kubeadm token create)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
添加节点到集群
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
kubeadm join k8smaster:6443 --token ${TOKEN} --discovery-token-ca-cert-hash sha256:${HASH}
|
|||
|
|
```
