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集群并安装了 istioctl 1.1.0 版本。 istio 安装附带一个位于 install/kubernetes/istio-demo.yaml 目录中的 istio-demo.yaml 文件。当我运行 kubectl apply -f install/kubernetes/istio-demo.yaml 命令时，我得到以下输出。

然后我列出了使用 kubectl get svc -n istio-system 的服务我正在查看服务

然后当我使用 kubectl get pod -n istio-system 列出 pods 时，我看不到 pods。我哪里错了？

rule.config.istio.io/tcpkubeattrgenrulerule created

kubectl get pod -n istio-system

P.s：更新问题： 1.

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

客户端版本：version.Info{主要版本：“1”，次要版本：“17”

Answer 1

您可以使用

检查哪些 api 支持当前 Kubernetes 对象

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

所以您正在尝试使用已弃用的 apiVersion extensions/v1beta1。这在 kubernetes 1.16 版本中已弃用。您似乎有一个高于 1.16 版本的 kubernetes 集群。

两种解决方案：

在 istio-demo.yaml 中 Deployment 将 apiVersion 从 extensions/v1beta1 更改为 apps/v1
Istio 1.1 很旧，所以建议将其升级到最新版本，这应该可以解决问题。

同时通过运行 kubectl version

验证 kubectl 客户端版本和 Kubernetes 服务器版本是否匹配
