Kubernetes多master部署---创建Node节点kubeconfig文件

Posted 2021-11-27 litzhiai

在Master01上执行kubeconfig.sh脚本

cd /opt/ssl

#cat kubeconfig.sh

# 创建 TLS Bootstrapping Token
export BOOTSTRAP_TOKEN=$(head -c 16 /dev/urandom | od -An -t x | tr -d ‘ ‘)
cat > token.csv <<EOF
${BOOTSTRAP_TOKEN},kubelet-bootstrap,10001,"system:kubelet-bootstrap"
EOF

#----------------------

# 创建kubelet bootstrapping kubeconfig
export KUBE_APISERVER="https://10.50.182.69:6443"

# 设置集群参数
kubectl config set-cluster kubernetes --certificate-authority=./ca.pem --embed-certs=true --server=${KUBE_APISERVER} --kubeconfig=bootstrap.kubeconfig

# 设置客户端认证参数
kubectl config set-credentials kubelet-bootstrap --token=${BOOTSTRAP_TOKEN} --kubeconfig=bootstrap.kubeconfig

# 设置上下文参数
kubectl config set-context default --cluster=kubernetes --user=kubelet-bootstrap --kubeconfig=bootstrap.kubeconfig

# 设置默认上下文
kubectl config use-context default --kubeconfig=bootstrap.kubeconfig

#----------------------

# 创建kube-proxy kubeconfig文件

kubectl config set-cluster kubernetes --certificate-authority=./ca.pem --embed-certs=true --server=${KUBE_APISERVER} --kubeconfig=kube-proxy.kubeconfig

kubectl config set-credentials kube-proxy --client-certificate=./kube-proxy.pem --client-key=./kube-proxy-key.pem --embed-certs=true --kubeconfig=kube-proxy.kubeconfig

kubectl config set-context default --cluster=kubernetes --user=kube-proxy --kubeconfig=kube-proxy.kubeconfig

kubectl config use-context default --kubeconfig=kube-proxy.kubeconfig

执行，拷贝文件到cfg：

sh -x kubeconfig.sh

cp -rf token.csv bootstrap.kubeconfig kube-proxy.kubeconfig /opt/kubernetes/cfg/

 

多master，需要将配置文件同步到其余几台master上。
