我正在尝试在本地minikube集群的kubernetes https://www.elastic.co/guide/en/cloud-on-k8s/current/index.html上部署 flex 模块。我已经安装了操作员。
当我在下面应用Elasticsearch集群时,出现以下pod错误:

kubectl获取pvc 最佳答案
上述错误意味着没有persistentVolume
可以绑定(bind)到PersistentVolumeClaim
。默认情况下,local-storage
不会真正动态创建persistentVolume
。
要使用local-storage
存储类的动态预配置机制,您需要配置local-storage
类,以便它可以预配置persistentVolume
。检查此讨论Kubernetes: What is the best practice for create dynamic local volume to auto assign PVs for PVCs?。
另外,如果不使用存储类的动态预配置机制,则需要使用可以绑定(bind)到persistentVolume
的hostPath
创建PersistentVolumeClaim
,但这不是推荐用于生产用途的解决方案。检查本指南here。PersistentVolumeClaim
将基于 flex Yaml中的volumeClaimTemplates
自动创建。因此,您不应该创建一个PersistentVolumeClaim
。
由于nodeSets
计数为2,因此创建了两个PersistentVolumeClaim
。因此,您需要创建两个persistentVolume
。
