istio 安装 gateway，vs 配置

环境要求： k8s集群

实现：

安装istio 1.8.1版本

Wget https://github.com/istio/istio/releases/tag/1.8.1下载istio-1.8.1-linux-amd64.tar.gz，并解压，然后进入解压后的istio-1.8.1目录

将bin/目录下的istioctl文件，cp到可执行的PATH路径，就可以使用istioctl命令了

istioctl install --set profile=demo

Kubectl  get pod -n istio-system

kubectl label  ns default istio-injection=enabled   default空间启用istio
