I try to build springboot and vue to use jenkins on k8s
However Im stuck in the job

I make the podtemplate like this

podTemplate(
    label: 'jenkins-slave-pod', 
    containers: [
        containerTemplate(name: 'git', image: 'alpine/git', command: 'cat', ttyEnabled: true),
        containerTemplate(name: "maven", image: "maven:latest", ttyEnabled: true, command: "cat"),
        containerTemplate(name: "docker", image: "docker:latest", ttyEnabled: true, command: "cat"),
        containerTemplate(name: "node", image: "node:lts-slim", command: "cat", ttyEnabled: true)
        //containerTemplate(name: "kubectl", image: "lachlanevenson/k8s-kubectl", command: "cat", ttyEnabled: true)
    ],
    //volume mount
    volumes: [
        hostPathVolume(hostPath: "/var/run/docker.sock", mountPath: "/var/run/docker.sock")
    ]
)

and when the stage to build like this

stage('build the source code via npm') {
            container('node') {
                sh 'npm install && npm run build'
            }
        }
stage('maven') {
            steps {
                container('maven') {
                    sh 'mvn package'
                    sh 'bash build.sh'
                }
            }
        }

I though the codes can work but it was not. the error below

I tried to solve the problem but there are not many information for it.
Network has no problem. ping, curl work well on server

It only does not work in POD
I guess it may be DNS PROBLEM but Im not sure

so if anybody figure out this problem, please help me

I tried to use the images to build by docker, it worked well
it does not work on k8s probably, it looks like network issue on k8s
