更新证书后,k3s服务不断重启

环境信息:
K3s 版本:
v1.20.5+k3s1

节点 CPU 架构、操作系统和版本::
Linux xx 5.11.6-1.el7.elrepo.x86_64 #1 SMP Thu Mar 11 08:51:58 EST 2021 x86_64 x86_64 x86_64 GNU/Linux

集群配置:
1 master 14 worker

问题描述:
执行更新证书操作后k3s服务不断重启

复现步骤:

timedatectl set-ntp no
for i in `ls /var/lib/rancher/k3s/server/tls/*.crt`; do echo $i; openssl x509 -enddate -noout -in $i; done
date -s 20220306
kubeclt get nodes
kubectl --insecure-skip-tls-verify -n kube-system delete secrets k3s-serving
rm -f /var/lib/rancher/k3s/server/tls/dynamic-cert.json
systemctl restart k3s
for i in `ls /var/lib/rancher/k3s/server/tls/*.crt`; do echo $i; openssl x509 -enddate -noout -in $i; done
timedatectl set-ntp yes
ntpdate ntp1.aliyun.com
date
systemctl status k3s

预期结果:

实际结果:
k3s服务启动失败且自动重启

我按照你的重现步骤没有重现。

正常情况下,v1.20.5+k3s1 版本的 K3s 在重启 K3s 服务时会自动轮换证书,不需要其余的 delete 操作。

针对你的情况,你可以使用下面两个命令,来看你现在集群中证书的有效期:

kubectl --insecure-skip-tls-verify get secret -n kube-system k3s-serving -o jsonpath='{.data.tls\.crt}' | base64 -d | openssl x509 -noout -text | grep Not

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

证书日期看着都正常

补充一个细节:
更新证书后同事增加了一个计划任务,本意是每 3 个月重启一次k3s 服务,结果不小心写成了* * * */3 * systemctl restart k3s,大概执行一个晚上多。

升级 bin 文件解决问题了,步骤:
https://github.com/k3s-io/k3s/releases?page=11 下载小版本升级二进制

systemctl stop k3s
mv /usr/local/bin/k3s{,.bak}
cp k3s  /usr/local/bin/k3s
chmod +x /usr/local/bin/k3s
systemctl start k3s

昨天我确实也看见你的 K8s 集群各节点的版本不一样了,现在都调整到同一个版本了?

只替换 k3s server,感谢昨天的支持。
我其实有点怀疑是计划任务重启次数太多造成的,但是也没有证据。
