ingress Whitelisting白名单机制

Whitelisting

To restrict the service in a way that only a list of IPs can access it, modify the ingress_rules.yaml to add the whitelist-source-range annotation:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-rules
  namespace: default
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/whitelist-source-range: '192.168.65.3/32'
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  tls:
  - hosts:
    - localhost
    secretName: tls-secret
  rules:
  - host: localhost
    http:
      paths:
      - path: /
        backend:
          serviceName: dni-function
          servicePort: 80

and deploy:

kubectl apply -f ./ingress_rules.yaml

Feel free to try different ranges and understand how you can block or enable access to your service.
