Knative Serving 自动伸缩与流量分配实践

Service 清单（含自动伸缩与流量）

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: api
  namespace: app
spec:
  template:
    metadata:
      annotations:
        autoscaling.knative.dev/minScale: "1"
        autoscaling.knative.dev/target: "100"
    spec:
      containers:
        - image: gcr.io/example/api:v2
  traffic:
    - latestRevision: true
      percent: 80
    - revisionName: api-00001
      percent: 20

总结

通过注解设定最小副本与目标并发，配合 traffic 字段实现多版本流量权重分配与灰度能力。
