Question

我正在尝试在Kubernetes集群上安装Istio。我创建了一个三节点群集，并安装了istioctl 1.1.0版本。 istio安装随附位于istio-demo.yaml目录中的install/kubernetes/istio-demo.yaml文件。运行kubectl apply -f install/kubernetes/istio-demo.yaml命令时，得到以下输出。

然后我使用kubectl get svc -n istio-system列出了服务，我看到了这些服务

然后，当我使用kubectl get pod -n istio-system列出豆荚时，我看不到豆荚。我要去哪里错了？

P.s：问题的最新动态： 1.

$ kubectl api-resources | grep deployment
deployments                       deploy       apps                           true
     Deployment

客户端版本：version.Info {主要：“ 1”，次要：“ 17”

您可以使用以下方法检查哪些api支持当前的Kubernetes对象：

$ kubectl api-resources | grep deployment
deployments                       deploy       apps                           true         Deployment

因此，您正在尝试使用不推荐使用的apiVersion extensions/v1beta1。 kubernetes版本1.16中已弃用该功能。您似乎拥有一个版本1.16以上的kubernetes集群。

两种解决方案：

在istio-demo.yaml中Deployment处，将apiVersion从extensions/v1beta1更改为apps/v1
Istio 1.1的版本很旧，因此建议将其升级到可以解决该问题的最新版本。

还要通过运行kubectl version来验证kubectl客户端版本和Kubernetes服务器版本是否匹配
