K3S证书过期解决方法

以ubuntu为例

1、关闭时间同步

timedatectl set-ntp no

2、查看k3s过期时间

for i in `ls /var/lib/rancher/k3s/server/tls/*.crt`; do echo $i; openssl x509 -enddate -noout -in $i; done

3、设置时间到过期前一个月

date -s 20211105

4、删除 secret k3s-serving

sudo kubectl --insecure-skip-tls-verify -n kube-system delete secrets k3s-serving

5、删除系统中的文件dynamic-cert.json

sudo rm -f /var/lib/rancher/k3s/server/tls/dynamic-cert.json

6、重启k3s

sudo service k3s restart

7、查看过期时间

for i in `ls /var/lib/rancher/k3s/server/tls/*.crt`; do echo $i; openssl x509 -enddate -noout -in $i; done

8、打开时间同步

timedatectl set-ntp yes
