运行 Kompose 后，我得到： pod has unbound immediate PersistentVolumeClaims

Question

什么问题？

我无法让正在使用卷的 pod 运行。在 Kubernetes 仪表板中，我收到以下错误：

为 pod“influxdb-6979bff6f9-hpf89”运行“VolumeBinding”过滤器插件：pod 具有未绑定的即时 PersistentVolumeClaims

我做了什么？

将Kompose convert 运行到我的docker-compose.yml 文件后，我尝试使用micro8ks kubectl apply -f . 启动pod（我使用的是micro8ks）我不得不用networking.k8s.io/v1 替换networkpolicy yaml 文件的版本（请参阅here ) 但除了这个改变，我什么都没改变。

如果集群没有StorageClass 可以动态配置PersistentVolume，或者它没有手动创建的PersistentVolume 以满足PersistentVolumeClaim，则PersistentVolumeClaim 将被解除绑定

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

要解决当前场景，您可以手动创建 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。不建议用于生产用途。考虑使用支持类型的外部块或文件存储here
