Given this snippet of a Kubernetes Deployment YAML for canary rollout, what percentage of traffic will go to the canary pods?

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp-canary
  labels:
    version: canary
spec:
  replicas: 2
  selector:
    matchLabels:
      app: myapp
      version: canary
  template:
    metadata:
      labels:
        app: myapp
        version: canary
    spec:
      containers:
      - name: myapp
        image: myapp:v2

Assuming the stable deployment has 8 replicas with label version: stable and the Service routes traffic evenly by label.
