Answer 1

We can add pod template in Jenkins pipeline script to pull our custom image and to run as a slave pod. Use this below format:

 pipeline { agent { kubernetes { defaultContainer 'jnlp' yaml """ apiVersion: v1 kind: Pod metadata: labels: some-label: some-label-value spec: containers: - name: maven image: maven:alpine command: - cat tty: true - name: busybox image: busybox command: - cat tty: true """ } } stages { stage('Run maven') { steps { container('maven') { sh 'mvn -version' } container('busybox') { sh '/bin/busybox' } } } } }
