I'm following this Link to setup Jenkins on Kubernetes cluster.
The environment information is mentioned below,
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
I have below yaml files.
deploy-jenkins.yaml
sa-jenkins.yaml
service-jenkins.yaml
volume-jenkins.yaml
PersistentVolume i want to use my master server local path, So in the volume-jenkins.yaml file I have updated path and values as below.
local:
path: /home/linux-user/kubernetes/jenkins
nodeAffinity:
required:
nodeSelectorTerms:
- matchExpressions:
- key: kubernetes.io/hostname
operator: In
values:
- master-server
When i apply the yaml files, My jenkins pod remain in pending status always.
Jenkins Pod status:-
# kubectl get pods -n jenkins

What is wrong with my yaml files? and let me know the way to solve the node conflict issue. Thanks in advance.
...i want to use my master server local path
Add nodeSelector and tolerations to your deployment spec:
apiVersion: apps/v1
kind: Deployment
...
spec:
...
template:
...
spec:
nodeSelector:
node-role.kubernetes.io/master: ""
tolerations:
- key: node-role.kubernetes.io/master
operator: Exists
containers:
- name: jenkins
...
