生成kubeconfig文件

openssl genrsa -out admin-key.pem 2048 
  openssl req -new -key admin-key.pem -out admin.csr -subj "/CN=admin/O=system:masters/OU=System" 
  openssl x509 -req -in admin.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out admin.pem -days 3650
 
  

export KUBE_APISERVER="https://10.0.3.241:6443"
# 设置集群参数
kubectl config set-cluster kubernetes \
  --certificate-authority=/opt/kubernetes/ssl/ca.pem \
  --embed-certs=true \
  --server=${KUBE_APISERVER} 
 
# 设置客户端认证参数
kubectl config set-credentials admin \
  --client-certificate=/opt/kubernetes/ssl/admin.pem \
  --embed-certs=true \
  --client-key=/opt/kubernetes/ssl/admin-key.pem 
 
# 设置上下文参数
kubectl config set-context kubernetes \
  --cluster=kubernetes \
  --user=admin 
 
# 设置默认上下文
kubectl config use-context kubernetes
