I have Jenkins running in my GKE cluster and I am trying to deploy some code from my GitHub on the same cluster. I am trying to execute docker commands inside a pod with "docker:19" image. My pipeline configuration is inside the Jenkinsfile in my repository and I'm executing a "Pipeline from SCM" build. However, the console output of the build looks like several pods are being created and terminated constantly.

Here's how Jenkins is set up inside the cluster

kubectl setup

aayush_pathak15@cloudshell:~/continuous-deployment-on-kubernetes/jenkins (multi-crud)$ kubectl get svc
NAME                                            TYPE           CLUSTER-IP     EXTERNAL-IP    PORT(S)                      AGE

I believe I have set up the kubernetes cloud correctly

Below are my Jenkinsfile and the Pod YAML inside which I want to execute my build

Jenkinsfile

pipeline {
  environment {
    SHA = sh(returnStdout: true, script: "git rev-parse HEAD")
  }
  agent {
    kubernetes {
      idleMinutes 5
      yamlFile 'buildPod.yaml'
    }
  }
  stages {
    stage('test') {
      steps {
        container('docker') {
          sh 'docker build -t aayushpathak/frontend-test -f ./client/Dockerfile.dev ./client'
          sh 'docker run aayushpathak/frontend-test -e CI=true npm test'
        }
      }
    }

    stage('build-push-production-images') {
      steps {
        container('docker') {
          sh 'docker build -t aayushpathak/frontend-test -f ./client/Dockerfile.dev ./client'
          sh 'docker run aayushpathak/frontend-test -e CI=true npm test'
        }
      }
    }

    stage('deploy') {
      environment {
        GC_HOME = '$HOME/google-cloud-sdk/bin'
        GC_KEY = credentials('jenkins-secret')
      }

      steps {
        container('docker') {
          sh("rm -r -f /root/google-cloud-sdk")
          sh("curl https://sdk.cloud.google.com | bash > /dev/null;")
          sh("${GC_HOME}/gcloud components update kubectl")
          sh("${GC_HOME}/gcloud auth activate-service-account --key-file=${GC_KEY}")
          sh("${GC_HOME}/kubectl apply -f k8s")
          sh("${GC_HOME}/kubectl set image deployments/server-deployment server=aayushpathak/fullstack-server:${SHA}")
          sh("${GC_HOME}/kubectl set image deployments/client-deployment client=aayushpathak/fullstack-client:${SHA}")
        }
      }
    }
  }
}
