elasticsearch 获取错误'；未知字段主机路径'；基于局部体积的Kubernetes弹性搜索

我正在尝试使用本地驱动器卷在kubernetes中部署弹性搜索，但出现以下错误，请更正。 使用ubuntu 16.04 kubernetes v1.11.0 Docker版本17.03.2-ce 使用本地卷获取错误“未知字段主机路径”Kubernetes Elasticsearch

error: error validating "es-d.yaml": error validating data: ValidationError(StatefulSet.spec.template.spec.containers[1]): unknown field "hostPath" in io.k8s.api.core.v1.Container; if you choose to ignore these errors, turn validation off with --validate=false

检查格式，主机路径不应位于容器部分下，“卷”不在其位置。

您的结构错误<代码>卷必须与

容器

处于同一级别

您可以找到。

但您确定，一旦容器重新启动，数据将得到相同的结果吗？我需要弹性搜索以确保每次都安全。您需要配置持久卷。详情请参阅。此外，我还看到volumeClaimTemplates已经在源代码中配置好了，您的yaml是从源代码中获得的：检查我上面提供的两个URL，并根据您的需要配置存储。实际上，使用

hostPath

在节点中存储任何应用程序的数据是一个非常糟糕的主意
