Question

我在谷歌云平台上使用kubernetes掌舵。

我的postgres部署出现以下错误：

SchedulerPredicates failed due to PersistentVolumeClaim is not bound

它似乎无法连接到持久存储，但我不明白为什么因为持久存储加载正常。

我已经尝试完全删除了helm版本，然后在google-cloud-console＆gt; “计算引擎”＆gt;磁盘;我删除了所有永久磁盘。最后尝试从掌舵图表安装，但postgres部署仍然没有连接到PVC。

我的数据库配置：

{{- $serviceName := "db-service" -}}
{{- $deploymentName := "db-deployment" -}}
{{- $pvcName := "db-disk-claim" -}}
{{- $pvName := "db-disk" -}}

apiVersion: v1
kind: Service
metadata:
  name: {{ $serviceName }}
  labels:
    name: {{ $serviceName }}
    env: production
spec:
  type: LoadBalancer
  ports:
  - port: 5432
    targetPort: 5432
    protocol: TCP
    name: http
  selector:
    name: {{ $deploymentName }}

          name: {{ $pvcName }}
      volumes:
      - name: {{ $pvcName }}
        persistentVolumeClaim:
          claimName: {{ $pvcName }}

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: {{ $pvcName }}
spec:
  accessModes:
    - ReadWriteOnce

apiVersion: v1
kind: PersistentVolume
metadata:
  name: {{ .Values.gcePersistentDisk }}
  labels:
    name: {{ $pvName }}
    env: production
  annotations:
    volume.beta.kubernetes.io/mount-options: "discard"
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteOnce
  gcePersistentDisk:
    fsType: "ext4"
    pdName: {{ .Values.gcePersistentDisk }}

这个kubenetes的配置是否正确？我已阅读文档，看起来这应该工作。我是Kubernetes的新手，掌舵，所以任何建议都值得赞赏。

编辑：

我添加了PersistentVolume并将其链接到PersistentVolumeClaim以查看是否有帮助，但似乎当我这样做时，PersistentVolumeClaim状态陷入“待定”状态（导致与之前相同的问题）。

Answer 1

对于此声明，您没有受约束的PV。您用于此声明的存储空间。您需要在PVC文件中提及它

由于未绑定PersistentVolumeClaim，SchedulerPredicates失败
