准备
注意: istioctl的安装要使用安装里的, 不要是用homebrew里的. github issue
curl -L https://istio.io/downloadIstio | sh -
cd istio-1.4.2
cp bin/istioctl /usr/local/bin/istioctl
安装前检查
istioctl verify-install
如果检查没问题, 会看到Install Pre-Check passed! The cluster is ready for Istio installation.
安装
istio有5种内建的安装配置1: remote, sds, default, demo, minimal
istioctl profile list
- minimal: 使用istio的流量管理所需组件的最小化安装
- default: 根据IstioControlPlane API的默认设置(建议用于生产部署)启用组件. 您可以通过运行命令istioctl profile dump显示默认设置.
- demo: 几乎安装所有的特性, 包括logging和tracing的比例为100%. 不适合生产环境, 负载太重
