我正在设置一个kind集群

Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.22.1) 🖼 
 ✓ Preparing nodes 📦 📦  
 ✓ Writing configuration 📜 
 ✓ Starting control-plane 🕹️ 
 ✓ Installing CNI 🔌 
 ✓ Installing StorageClass 💾 
 ✓ Joining worker nodes 🚜 
 ✓ Waiting ≤ 5m0s for control-plane = Ready ⏳ 
 • Ready after 0s 💚

然后尝试按照说明关于 1.6 版安装 ECK 运算符

kubectl apply -f https://download.elastic.co/downloads/eck/1.6.0/all-in-one.yaml

但是进程失败了,好像kind不支持CRDs...是这样吗?

Answers

您在这里看到的问题与种类无关,而是您尝试应用的清单使用过时的 API 版本,这些版本已在 Kubernetes 1.22 中删除

具体来说,清单正在使用 customresourcedefinition 对象和验证 admissionwebhook 对象的 v1beta1 版本

apiVersion: apiextensions.k8s.io/v1beta1
kind: CustomResourceDefinition

如中所述,这篇文章是 1.22 进入时删除的版本之一。

对此有几个修复。首先,您可以获得清单,只需更改 customresourcedefinitions 以使用新的 API 版本apiextensions.k8s.io/v1并验证admissionwebhook 以使用admissionregistration.k8s.io/v1。

另一个解决方法是使用旧版本的 Kubernetes。如果您使用 1.21 或更早版本,则不会出现该问题,因此 kind create cluster --image=kindest/node:v1.21.2之类的东西应该可以工作。
