You oversee an application operating within Google Kubernetes Engine (GKE) and employing the blue/green deployment approach. Portions of the Kubernetes manifests are provided below: apiVersion: apps/v1 kind: Deployment metadata: name: green-app labels: app: my-app version: green --- apiVersion: apps/v1 kind: Deployment metadata: name: blue-app labels: app: my-app version: blue --- apiVersion: v1 kind: Service metadata: name: appservice spec: selector: app: my-app version: green --- apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: ingress-app spec: defaultBackend: service: name: appservice The green-app Deployment was recently updated to incorporate a new application version. However, after the update, a substantial portion of user requests is failing, a behavior not observed during testing. Your task is to minimize the impact on users and facilitate developers in diagnosing the issue. What action should you take?
