service account "default", retry after the token is automatically created and added to the service

解决方法

1.首先生成密钥：

openssl genrsa -out /etc/kubernetes/serviceaccount.key 2048

2.编辑/etc/kubenetes/apiserver
添加以下内容

KUBE_API_ARGS="--service_account_key_file=/etc/kubernetes/serviceaccount.key"

3.编辑/etc/kubernetes/controller-manager

4. 重启服务

systemctl restart etcd kube-apiserver kube-controller-manager kube-scheduler
