In this course, you will learn how to configure circuit breaker with MOSN as the data plane of Istio.

Circuit Breaking is a critical component of distributed systems. Circuit breaking lets applications configure failure thresholds that ensure safe maximums, allowing components to fail quickly and apply back pressure as soon as possible. Applying correct circuit breaking thresholds helps to save resources which otherwise are wasted in waiting for requests (timeouts) or retrying requests unnecessarily. One of the main advantages of the circuit breaking implementation in MOSN is that the circuit breaking limits are applied at the network level.

MOSN with Istio

Istio is the most popular Service Mesh, it use Envoy as the default data plane, MOSN is aim to be the alternative cloud native data plane that support Enovy’s xDS.


在本课程中,您将了解如何将 MOSN 作为 Istio Service Mesh 中的数据平面时,配置熔断。

熔断是分布式系统的关键组成部分。 熔断使应用程序可以配置故障阈值,以确保安全最大化,从而允许组件快速故障并尽快施加反压。 应用正确的断路阈值有助于节省资源,否则这些资源将浪费在等待请求(超时)或不必要地重试请求上。 MOSN中实现熔断的主要优点之一是断路限制适用于网络级别。

Congratulations! You have compled the MOSN with istio circuitbreaker course, if you are interested in MOSN or have any questions, please leave a message.

MOSN is a powerful cloud native proxy written in Golang. As a cloud-native network data plane, MOSN is designed to provide services with multi-protocol, modular, intelligent, and secure proxy capabilities. MOSN can be integrated with any Service Mesh that supports the xDS API. It can also be used for other purposes, such as independent Layer 4 or 7 load balancer, API gateway, and cloud-native ingress

Step 1 of 5

Step 1: Install Istio with MOSN

本教程提供中文版说明,请翻至本页底部。

This tutorial will automatically help you start a Kubernetes cluster with 2 nodes (one master node and one worker node), Kubernetes version is v1.14.0.

Download istio install file: curl -L https://istio.io/downloadIstio | ISTIO_VERSION=1.5.2 sh -

Add directory to your environment path variable with: export PATH="$PATH:/root/istio-1.5.2/bin"

Install operator for install cluster: istioctl operator init

Install cluster with operator: istioctl manifest apply --set profile=demo --set .values.global.proxy.image="mosnio/proxyv2:1.5.2-mosn" --set meshConfig.defaultConfig.binaryPath="/usr/local/bin/mosn

Wait a minute later. Check all component start succ for Status Running: kubectl get pods -n istio-system -o wide


本教程将自动帮您启动一个包含2个节点的 Kubernetes 集群(包含一个 master 节点,一个 worker 节点),Kubernetes 版本为 v1.14.0。

安装 Istio 集群

下载 Istio 安装文件: curl -L https://istio.io/downloadIstio | ISTIO_VERSION=1.5.2 sh -

添加文件夹到环境变量: export PATH="$PATH:/root/istio-1.5.2/bin"

安装 Operator 用来安装集群: istioctl operator init

使用 Operator 安装集群: istioctl manifest apply --set profile=demo --set .values.global.proxy.image="mosnio/proxyv2:1.5.2-mosn" --set meshConfig.defaultConfig.binaryPath="/usr/local/bin/mosn

等待几分钟,检查所有的组件启动成功,状态都是 Running: kubectl get pods -n istio-system -o wide
