我正在尝试使用最新的稳定版通过 helm 安装 postgres ，但它没有正确安装持久卷。我正在将它安装在 Minikube 中，由于某种原因，它似乎无法正确托管安装。

错误（在部署、pod 和副本集上）

PersistentVolumeClaim 未绑定：“postgres-postgresql”错误：lstat /tmp/hostpath-provisioner/pvc-c713429d-e2a3-11e7-9ca9-080027231d54：没有这样的文件或目录同步 pod 错误

当我查看持久卷时，它似乎运行正常。万一这有帮助，我的持久卷 yaml：

{
  "kind": "PersistentVolume",
  "apiVersion": "v1",
  "metadata": {
    "name": "pvc-c713429d-e2a3-11e7-9ca9-080027231d54",

    },

    },
    "persistentVolumeReclaimPolicy": "Delete",
    "storageClassName": "standard"
  },
  "status": {

}

持久卷声明 Yaml：

任何援助将不胜感激。

您可能会遇到这个问题：https ://github.com/kubernetes/minikube/issues/2256

问题是主机路径卷配置程序中存在一个错误，当部署资源中存在“子路径”字段时遇到错误（如果该字段具有空值则发生事件）。

这是一个对我有用的解决方法 - 解压缩 postgresql 图表并在 deployment.yaml 中注释掉以下行：

      # subPath: {{ .Values.persistence.subPath }}

然后重新部署修改后的图表。如果您依赖 'subPath' 字段，则此解决方法对您不起作用。

注意：这个问题也出现在 Docker-for-Mac 上的 Kubernetes 上（这是我遇到的地方）。
