我正在尝试使用最新的 stable通过helm安装postgres并且它没有正确安装持久卷.我在Minikube中安装它,由于某种原因它似乎无法正确地hostMount.

错误(在部署,窗格和副本集上)

PersistentVolumeClaim is not bound: “postgres-postgresql” Error: lstat
/tmp/hostpath-provisioner/pvc-c713429d-e2a3-11e7-9ca9-080027231d54: no
such file or directory Error syncing pod

当我查看持久性卷时,它似乎正在正常运行.如果它有帮助,这是我的持久卷yaml：

{
  "kind": "PersistentVolume","apiVersion": "v1","metadata": {
    "name": "pvc-c713429d-e2a3-11e7-9ca9-080027231d54","selfLink": "/api/v1/persistentvolumes/pvc-c713429d-e2a3-11e7-9ca9-080027231d54","uid": "c71850e1-e2a3-11e7-9ca9-080027231d54","resourceVersion": "396568","creationTimestamp": "2017-12-16T20:57:50Z","annotations": {

  },"spec": {

    },"accessModes": [

    ],"claimRef": {

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

持续量索赔Yaml：

{
  "kind": "PersistentVolumeClaim","metadata": {
    "name": "postgres-postgresql","selfLink": "/api/v1/namespaces/default/persistentvolumeclaims/postgres-postgresql","resourceVersion": "396588","labels": {

    }
  },"spec": {
    "accessModes": [
      "ReadWriteOnce"
    ],"resources": {
      "requests": {
        "storage": "8Gi"
      }
    },"volumeName": "pvc-c713429d-e2a3-11e7-9ca9-080027231d54","status": {

    }
  }
}

任何援助将不胜感激.

解决方法

您可能遇到此问题： https://github.com/kubernetes/minikube/issues/2256

问题是当部署资源中存在“subPath”字段时,主机路径卷配置器中出现错误,如果该字段具有空值,则会发生错误.

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.如果您依赖于“subPath”字段,则此解决方法将不适合您.

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).
