It looks like the secret is not mounted for deployment you can do it following
create secret using
kubectl create secret jenkins --from-literal jenkins_password="ADD YOUR SECRET TOKEN Which you will find in jenkins pod logs"
and mount it like this
apiVersion: apps/v1
kind: Deployment
metadata:
name: jenkins
spec:
replicas: 1
selector:
matchLabels:
app: jenkins
template:
metadata:
labels:
app: jenkins
spec:
containers:
- name: jenkins
image: jenkins/jenkins:lts
env:
- name: JENKINS_PASSWORD
valueFrom:
secretKeyRef:
key: jenkins_password
name: jenkins
ports:
- name: http-port
containerPort: 8080
- name: jnlp-port
containerPort: 50000
volumeMounts:
- name: jenkins-data
mountPath: /var/jenkins_home
volumes:
- name: jenkins-data
persistentVolumeClaim:
claimName: jenkins-data
Next time it will not ask your the token. Also I would highly recommend to use PVC for the data to persist. if you install plugin/or configure jobs etc. next time when you restart jenkin, the plugins/jobs will be gone.
so for pvc you can use it like this
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: jenkins-data
namespace: jenkins
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 10Gi
