Pods terminated immediately from Jenkins to Kubernetes cluster

I have jenkins running on Windows as a service on 127.0.0.1:8080
and minikube running on 192.168.99.101
below is the pipeline for Jenkins job

podTemplate(
  activeDeadlineSeconds: 240,
  name: 'default',
  inheritFrom: 'default',
  nodeSelector: 'key1=value1,kubernetes.io/hostname=minikube',
  containers: [
  containerTemplate(name: 'maven', image: 'maven:3.3.9-jdk-8-alpine', ttyEnabled: true, command: 'cat' ),
  containerTemplate(name: 'jnlp', image: 'jenkins/jnlp-slave:3.35-2-alpine', args: '${computer.jnlpmac} ${computer.name}')
]) {

node(POD_LABEL) {
    stage('Get a Maven project') {
        git 'https://github.com/<project>.git/'
        container('maven') {
            stage('Build a Maven project') {
                sh 'mvn -B -gs ./settings.xml clean install'
            }
        }
    }
  }
}

The following are the logs for from the kubernetes:

$ kubectl get -a pods --watch

The following is the console's output from the jenkins job

I have the same problem since yesterday. Navigate to Configure Clouds --> kubernetes --> Pod Template. Set Pod Retention as 'Always'. Pods will stay in error status. You can get the pod logs with command kubectl logs --all-containers and see the error reason. In my case Jenkins URL and Jenkins Tunnel is not set properly.

Refer to https://www.youtube.com/watch?v=DCkzdsffeh0

It gives details for jenkins and kubernetes plugin configuration
