Istio ingress and egress lab. 入口 网关 （ingress gateway ）是 istio 重要的资源对象之一，是用于管理网格边缘入站的流量，通过入口 网关 就可以很轻松的将网格内部的服务暴露到外部提供访问。. Istio is designed to use envoy deployed on each pod as sidecars to intercept and proxy network traffic between microservices in service mesh. Inside the mesh there […] A service is bound to a clusterip, which is a virtual ip address, and no matter what happens to the backend pods, the clusterip never changes, so a client can always send requests to the clusterip. In this post, we’ll look at what a virtualservice resource is, how it relates to a standard ingress resource, and add a virtualservice resource to the cluster to route and modify the requests made by the proxy pod to the webserver service.
