You need to create the cluster role binding for the service account jenkins.

1. Create a file with the name sa.yaml and add below content in it

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: jenkins-role-binding
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: jenkins
  namespace: jenkins

2. Create the role binding using the command.

kubectl apply -f sa.yaml
