在运行 Kompose 之后我得到：pod has unbound immediate PersistentVolumeClaims

Question

有什么问题？

我无法获取正在使用卷的 pods 运行。在 Kubernetes 仪表板中，我收到以下错误：

running "VolumeBinding" filter plugin for pod "influxdb-6979bff6f9-hpf89": pod has unbound immediate PersistentVolumeClaims

我做了什么？

在运行 Kompose convert 到我的 docker-compose.yml 文件后，我尝试用 micro8ks kubectl apply -f . 启动 pods （我使用的是 micro8ks）我不得不更换带有 networking.k8s.io/v1 的 networkpolicy yaml 文件的版本（参见 here）但除了这个更改，我没有做任何更改。

如果集群没有可以动态配置 PersistentVolume 的 StorageClass 或者没有手动创建的 PersistentVolume，PersistentVolumeClaim 将被解除绑定满足 PersistentVolumeClaim

这里是 guide 关于如何配置 pod 以使用 PersistentVolume

解决当前场景可以手动创建PV

apiVersion: v1
kind: PersistentVolume
metadata:
  name: task-pv-volume
  labels:
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 100Mi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/mnt/data"

请注意 hostPath 的用法仅作为示例。不推荐用于生产用途。考虑使用受支持类型的外部块或文件存储 here
