K8s - Ingress 限流

一、限制连接数&请求速度
以下是一个简单的Ingress限流配置示例

apiVersion: extensions/v1beta1

kind: Ingress
metadata:
name: my-ingress
annotations:

nginx.ingress.kubernetes.io/limit-connections: "10" #设置连接数上限为10
nginx.ingress.kubernetes.io/limit-rpm: "100"        #设置每分钟请求数上限为100

spec:
rules:

- host: example.com
  http:
    paths:
    - path: /
      backend:
        serviceName: my-service
        servicePort: 80

二、限制每个IP的请求速度

apiVersion: extensions/v1beta1

kind: Ingress
metadata:
name: my-ingress
annotations:

nginx.ingress.kubernetes.io/limit-req-rate: "5r/s" #设置每个IP地址的请求速率为5次/秒

spec:
rules:

- host: example.com
  http:
    paths:
    - path: /
      backend:
        serviceName: my-service
        servicePort: 80
