Istio安装 #

此文档介绍如何安装一个可用的 1.11版本istio。由于官方istio的镜像包所属docker.io，下载的时候可能会有限制，所以我们维护了 istio 1.11.5 版本的istio官方镜像，方便进行安装测试。

下载 istioctl #

使用linux安装

wget http://release.solarmesh.cn/istio/istioctl/istioctl-1.11.5.tar.gz
tar -xvf istioctl-1.11.5.tar.gz

安装istio #

初始化 IstioOperator

istioctl operator init --hub registry.cn-shenzhen.aliyuncs.com/solarmesh --tag 1.11.5
