通过 Minikube 在本地运行 Kubernetes 总是返回 304 not modified resource

Question

我正在使用 Nginx 入口控制器将流量引导到特定服务，尽管现在只有一个。该服务指向一个 Node.js 应用程序，从服务器返回的 html 始终是 304 未修改。有人对我如何返回 200 并防止缓存有任何想法吗？

这是我的 Ingress 设置：

apiVersion: networking.k8s.io/v1beta1 # for versions before 1.14 use extensions/v1beta1
kind: Ingress
metadata:
  name: kludge-ingress
  namespace: kludge
  annotations:
    # use the shared ingress-nginx
    kubernetes.io/ingress.class: "nginx"
spec:
  rules:
    - host: kludge.local
      http:
        paths:
          - path: /
            backend:
              serviceName: kludge-front-end
              servicePort: 80

服务：

apiVersion: v1
kind: Service
metadata:
  name: kludge-front-end
  namespace: kludge
spec:
  type: NodePort
  selector:
    name: kludge-front-end
  ports:
    - name: http
      protocol: TCP
      nodePort: 30080
      port: 80
      targetPort: 3000

部署：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: kludge-front-end
  namespace: kludge
spec:
  replicas: 3
  selector:
    matchLabels:
      name: kludge-front-end
  template:
      metadata:
        namespace: kludge
        labels:
          name: kludge-front-end
      spec:
        containers:
          - name: kludge-front-end
            image: gibson445/kludge-front-end
            ports:
              - containerPort: 3000
            imagePullPolicy: Never

Answer 1

很有可能您实际上希望 configuration-snippet 添加标头 Cache-Control。

例子：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: myingress
  namespace: mynamespace
  annotations:
    nginx.ingress.kubernetes.io/configuration-snippet: |
      add_header Cache-Control "max-age=0, no-cache, no-store, must-revalidate";
