Pre Install

Istio安装 #

此文档介绍如何安装一个可用的 1.13.9 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 1.13.9 版本的istio官方镜像，方便进行安装测试。

下载 solarmesh 安装包 #

如已经有安装包，省略以下步骤

wget http://release.solarmesh.cn/solar/v1.12/solar-v1.12.1-linux-amd64.tar.gz
tar -xvf solar-v1.12.1-linux-amd64.tar.gz
export PATH=$PATH:$PWD/solar/bin/
chmod +x $PWD/solar/bin/istioctl

安装istio #

初始化 IstioOperator

istioctl operator init --hub registry.cn-shenzhen.aliyuncs.com/solarmesh --tag 1.13.9

安装 istio。
