Rancher无法登录 容器报错X509：certificate has expired or is not ye valid

在某天需要发布新版本的时候，发现rancher无法登录，于是到服务器上查看rancher日志，发现以下内容：

 参考rancher文档中独立容器Rancher Server证书更新解决

1. 进入容器  <rancher_server_id>为容器id

docker exec -it <rancher_server_id> /bin/bash

2.容器内操作

kubectl --insecure-skip-tls-verify -n kube-system delete secrets k3s-serving
kubectl --insecure-skip-tls-verify delete secret serving-cert -n cattle-system
rm -f /var/lib/rancher/k3s/server/tls/dynamic-cert.json
exit

3.重启容器

docker restart <rancher_server_id>

4.执行以下参数刷新参数，并再次重启容器  <server-url> 为rancher登录地址

curl --insecure -sfL https://<server-url>/v3
