运行Kompose后，我得到:pod具有未绑定的即时PersistentVolumeClaims

Question

有什么问题？

我无法运行使用卷的 pod。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 立即具有未绑定的持久卷声明

我做了什么？

在对我的docker-compose.yml文件运行Kompose convert后，我尝试用micro8ks kubectl apply -f .启动pods(我正在使用micro8ks(，我不得不用networking.k8s.io/v1替换网络策略yaml文件的版本(见这里(，但除了这个更改，我没有改变任何东西。

Answer 1

如果集群没有可以动态预配PersistentVolume的StorageClass，或者没有手动创建的PersistentVolume来满足PersistentVolumeClaim，则PersistentVolumeClaim将被取消绑定

以下是有关如何配置 Pod 以使用PersistentVolume的指南

要解决当前方案，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的使用仅作为示例。不建议将其用于生产用途。考虑使用此处支持类型的外部块或文件存储
