istioctl 安装集成配置 Jarger
前言
- 这教程是istio的Jarger的配置, 是istio写的Jarger配置文件, 不是Jarger官网的配置, 它是比较好集成了Jarger, 当然也只是简单的配置, 不包括性能和安全性问题
- 适用于使用Jarger搭配istio
- istio有helm和istioctl安装方式, 这里使用istioctl安装istio, 理由是比较简单安装
安装
https://istio.io/latest/zh/docs/setup/install/istioctl/
配置
- 修改github的配置文件, 把
ClusterIP替换为NodePort, 启用Web UI

测试
查看Web UI的端口, 假设istio安装在istio-system这个命名空间:
kubectl get svc -n istio-system -owide

Web UI的端口为30976, 浏览器访问即可:
