1.部署完之后pod起不來
kubectl describe pod jenkins-74b4c59549-lm6qj -n jenkins-k8s
原因：
node2節點沒安裝nfs-utils，導致掛載pvc失敗
解決辦法：
在node2節點執行
yum install -y nfs-utils
systemctl start nfs
systemctl enable nfs
2.啟動狀態不正常
[root@master1 ~]# kubectl logs jenkins-74b4c59549-5r2k6 -n jenkins-k8s
touch: cannot touch '/var/jenkins_home/copy_reference_file.log': Permission denied
Can not write to /var/jenkins_home/copy_reference_file.log. Wrong volume permissions?
權限不夠
[root@master1 ~]# chown -R 1000.1000 /data/v2
[root@master1 ~]# kubectl delete -f jenkins-deployment.yaml
deployment.apps "jenkins" deleted
[root@master1 ~]# kubectl apply -f jenkins-deployment.yaml
deployment.apps/jenkins created
[root@master1 ~]# kubectl get pods -n jenkins-k8s
