The Sumo Logic App for Istio provides visibility into the health and performance of Istio and its control plane components, including Mixer, Galley, Citadel, Pilot and Envoy. Pilot分为Pilot-agent和Pilot-server两部分,Pilot-agent位于数据平面,Pilot-server位于控制平面。 Pilot-agent在Proxy部分有过说明就不再重复。 Pilot-server对应图中的Discovery Service,主要功能是在Kubernetes的Controller中注册Event事件,对Service、Pod、Endpoint、Node的信息变更进行监听。. @sbezverk could you please run kubectl get pod -oyaml on the pilot pod and get the state of your containers, to see which 1/2 is actually down? The problem may be with the istio-proxy container not with pilot-discovery anymore. com/istio/istio/pilot/pkg/model" Copyright 2019 Istio Authors Licensed under the Apache License, Version 2.

Istio supports transparent proxying so a microservice uses only the native service discovery mechanisms of Kubernetes. Install and use Istio in Azure Kubernetes Service (AKS) 10/09/2019; 14 minutes to read; In this article. With this interface, tools like NSX Service Mesh can provide service observability (only NSX Service Mesh does that across Kubernetes clusters in multiple clouds and is. Christopher Luciano and Nimesh Bhatia explain how a Pilot adaptor for Consul or Eureka can use Envoy proxies to route and monitor applications that. Pilot  - provides service discovery for the Envoy sidecars, traffic management capabilities for intelligent routing. We dive into Istio's Pilot, the component responsible for programming the sidecar Envoy proxies that make up the Istio service mesh. Pilot abstracts platform-specific service discovery mechanisms and synthesizes them into a standard format that any sidecar conforming with the Envoy data plane APIs can consume. Start Istio proxy discovery service.
