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，我得到了以下输出。

然后我使用kubectl get svc -n istio-system 列出了服务，我正在查看服务

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

P.s：关于问题的更新： 1.

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

1. 客户端版本：version.Info{Major:"1", Minor:"17"

Answer 1

您可以使用检查哪些 api 支持当前的 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 版本 1.16 中已被弃用。您似乎有一个高于 1.16 版本的 kubernetes 集群。

两种解决方案：

1. 在istio-demo.yaml 中，无论您有Deployment，将apiVersion 从extensions/v1beta1 更改为apps/v1

2. Istio 1.1 已经很老了，所以建议将其升级到最新版本，这样应该可以解决问题。

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