Kubernetes多master部署（5）---创建Node节点kubeconfig文件

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。
