1. 题目

Using Kubernetes context cluster-2 
Configure circuit breaker and outlier detection in the DestinationRule 
cb-destination for the host backend.cb.svc.cluster.local in the cb namespace. 
Configure as follows:Connection pool size (HTTP1): 50
Maximum number of concurrent HTTP2 requests: 100
Maximum number of requests per connection: 5
Number of consecutive 5xx errors: 5

2. 解题

2.1 获取模板

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:name: reviews-cb-policy
spec:host: reviews.prod.svc.cluster.localtrafficPolicy:connectionPool:tcp:maxConnections: 100http:http2MaxRequests: 1000maxRequestsPerConnection: 10outlierDetection:consecutive5xxErrors: 7interval: 5mbaseEjectionTime: 15m

2.2 整理yaml

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:name: cb-destinationnamespace: cb
spec:host: backend.cb.svc.cluster.localtrafficPolicy:connectionPool:tcp:maxConnections: 50http:http2MaxRequests: 100maxRequestsPerConnection: 5outlierDetection:consecutive5xxErrors: 5interval: 3mbaseEjectionTime: 8m

这题考试时候ns下并没有资源所以也没法测,改起来也方便.只要yaml没错也就对了.
