/**
 * This pipeline will build and deploy a Docker image with Kaniko
 * https://github.com/GoogleContainerTools/kaniko
 * without needing a Docker host
 *
 * You need to create a jenkins-docker-cfg secret with your docker config
 * as described in
 * https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/#create-a-secret-in-the-cluster-that-holds-your-authorization-token
 *
 * ie.
 * kubectl create secret docker-registry regcred --docker-server=https://index.docker.io/v1/ --docker-username=csanchez --docker-password=mypassword --docker-email=john@doe.com
