istio实现熔断功能

	熔断的目的是在出现故障或异常情况时，对服务进行自动的限流和隔离，以保护整个系统的稳定性和可用性。
 	上传httpbin镜像和fortio镜像到harbor

 docker tag kong/httpbin:latest 172.16.80.140/istio/httpbin
 docker push 172.16.80.140/istio/httpbin:latest
 docker tag fortio/fortio:latest_release 172.16.80.140/istio/fortio:latest_release
 docker push 172.16.80.140/istio/fortio:latest_release

在samples/httpbin下面，修改httpbin.yaml中的镜像为harbor镜像

apiVersion: v1
kind: ServiceAccount
metadata:
  name: httpbin
---
apiVersion: v1
kind: Service
metadata:
  name: httpbin
  labels:
    app: httpbin
    service: httpbin
spec:
  ports:
  - name: http
    port: 8000
    targetPort: 80
  selector:
    app: httpbin
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: httpbin
spec:
  replicas: 1
  selector:
    matchLabels:
      app: httpbin
      version: v1
  template:
    metadata:
      labels:
        app: httpbin
        version: v1
    spec:
      serviceAccountName: httpbin
      containers:
      - image: 172.16.80.140/istio/httpbin:latest
        imagePullPolicy: IfNotPresent
        name: httpbin
        ports:
        - containerPort: 8080

在这里插入图片描述

将service httpbin改为nodeport
