大使限速措施无法正常工作

问题描述

我正在尝试按照this教程与大使进行速率限制。我正在使用minikube和本地docker镜像。我已经测试了所有api在部署到Kubernetes后是否正确响应，只有限速功能不起作用。

这是我的deploy.yaml

---
apiVersion: v1
kind: Service
Metadata:
  name: nodejs-deployment
spec:
  ports:
  - name: http
    port: 80
    targetPort: 3000
  - name: https
    port: 443
    targetPort: 3000
  selector:
    app: nodejs-deployment
---
apiVersion: apps/v1
kind: Deployment
Metadata:
  name: nodejs-deployment
spec:
  selector:
    matchLabels:
      app: nodejs-deployment
  replicas: 2
  template:
    Metadata:
      labels:
        app: nodejs-deployment  
    spec:
      containers: 
      - name: nodongo
        image: soham/nodejs-starter
        imagePullPolicy: "Never"
        ports:
        - containerPort: 3000

这是我的rate-limit.yaml

---

apiVersion: getambassador.io/v2

kind: Mapping

Metadata:

  name: nodejs-backend

spec:

  prefix: /delete/

  service: nodejs-deployment

  labels:

    ambassador:

      - request_label_group:

        - delete

---

apiVersion: getambassador.io/v2

kind: RateLimit

Metadata:

  name: backend-rate-limit

spec:

  domain: ambassador

  limits:

  - pattern: [{generic_key: delete}]

    rate: 1

    unit: minute

    injectResponseHeaders:

    - name: "x-test-1"

      value: "my-rl-test"

当我执行命令时-curl -vLk 10.107.60.125/delete/

正在返回

*   Trying 10.107.60.125:80...
* TCP_NODELAY set
* Connected to 10.107.60.125 (10.107.60.125) port 80 (#0)

我得到的响应是200，但是我期望429错误代码。
