开始部署istio
1.下载源码
wget https://github.com/istio/istio/releases/download/1.1.0.snapshot.1/istio-1.1.0.snapshot.1-linux.tar.gz
2.解压
tar -zxvf istio-1.1.0.snapshot.1-linux.tar.gz
修改yaml文件
把谷歌的镜像改为990570827镜像库，example 990570827/proxyv2:1.1.0.snapshot.1
3.部署
cd istio-1.1.0.snapshot.1
[root@master-47-35 istio-1.1.0.snapshot.1]# kubectl create -f install/kubernetes/istio-demo.yaml
查看部署结果
[root@master-47-35 istio-1.1.0.snapshot.1]# kubectl get all -n istio-system
