我遵循这个链接在Kubernetes集群上安装Jenkins。
下面介绍了环境信息，
Environment:-
On-Premise Physical Server
# kubectl get nodes
NAME STATUS ROLES AGE VERSION
master-server Ready master 2d23h v1.19.16
node-server1 Ready worker1 2d23h v1.19.16
node-server2 Ready worker2 2d23h v1.19.16
node-server3 Ready worker3 2d23h v1.19.16我有下面的yaml文件。
deploy-jenkins.yaml
sa-jenkins.yaml
service-jenkins.yaml
volume-jenkins.yamlPersistentVolume我想使用我的master服务器本地路径，所以在volume-jenkins.yaml文件中，我更新了path和values，如下所示。
local:
path: /home/linux-user/kubernetes/jenkins
nodeAffinity:
required:
nodeSelectorTerms:
- matchExpressions:
- key: kubernetes.io/hostname
operator: In
values:
- master-server当我应用yaml文件时，我的jenkins始终处于pending状态。

...i want to use my master server local path
将nodeSelector和tolerations添加到部署规范中：
apiVersion: apps/v1
kind: Deployment
...
spec:
...
template:
...
spec:
nodeSelector:
node-role.kubernetes.io/master: ""
tolerations:
- key: node-role.kubernetes.io/master
operator: Exists
containers:
