elasticsearch - pod具有未绑定(bind)的立即PersistentVolumeClaims ECK(Elasticsearch on Kubernetes)

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

上面的错误意味着没有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存储类的动态配置机制，您需要配置local-storage类，以便它可以配置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。
