前提
- Kubernetes 集群环境 （基于centos7 搭建 1.14 kubernetes 集群）
- Istio 1.2.4 release
安装步骤
- 下载 Istio 1.2.4
curl -L https://git.io/getLatestIstio | ISTIO_VERSION=1.2.4 sh -
目录简介：
- 在 install/ 目录中包含了 Kubernetes 安装所需的 .yaml 文件
- samples/ 目录中是示例应用
- istioctl 客户端文件保存在 bin/ 目录之中。istioctl 的功能是手工进行 Envoy Sidecar 的注入。
- istio.VERSION 配置文件
这里咱们基本不适用istioctl 操作所以就不配置环境变量了，有需要的自行配置。
安装istio
安装istio crd
for i in install/kubernetes/helm/istio-init/files/crd*yaml; do kubectl apply -f $i; done
kubectl get crd | grep istio

部署 istio 控制器
kubectl apply -f install/kubernetes/istio-demo.yaml
确认 istio-system pod 、svc 状态 :
kubectl get pod,svc -n istio-system
