kubernetes - 无法在Kops实例上安装istio

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安装随附在istio-demo.yaml目录中的install/kubernetes/istio-demo.yaml文件。当我运行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，我看到了服务

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

附:问题的最新动态:

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

客户端版本:version.Info {主要:“1”，次要:“17”

Answer 1

您可以使用以下命令检查哪些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:

在您拥有istio-demo.yaml的Deployment中，将apiVersion从extensions/v1beta1更改为apps/v1

Istio 1.1相当老，因此建议将其升级到最新版本，以解决此问题。

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