Your application is deployed in a Google Kubernetes Engine (GKE) cluster. When releasing a new version, your CI/CD pipeline updates the spec.template.spec.containers[0].image field to point to the new Docker image. You want to ensure that at least one replica of the new version is deployed while keeping the old replicas running until the new replica becomes healthy.

What modification should you apply to the following GKE Deployment configuration?

apiVersion: apps/v1

  name: ecommerce-frontend-deployment

  replicas: 3
