Error: pod has unbound immediate PersistentVolumeClaims
Error: pod has unbound immediate PersistentVolumeClaims
我正在尝试 运行 使用 kubeless 的 kafka，但我收到此错误 pod has unbound immediate PersistentVolumeClaims。我已经使用 rook 和 ceph 创建了一个持久卷，并尝试将这个持久卷与 kubeless kafka 一起使用。但是，当我 运行 代码时，我得到 "pod has unbound persistent volume claims"
我做错了什么？

我的 minikube 中出现了同样的错误。忘记为我的 statefulSets 创建卷。
已创建 PVC。需要注意 storageClassName，检查 througt availiable（我在仪表盘上做了）。
{
"kind": "PersistentVolumeClaim",
"apiVersion": "v1",
"metadata": {
"name": "XXXX",
"namespace": "kube-public",
"labels": {
"kubeless": "XXXX"
}
},
"spec": {
"storageClassName": "hostpath",
"accessModes": [
"ReadWriteOnce"
],
"resources": {
"requests": {
"storage": "1Gi"
}
}
}
}
我得到了持久卷。
然后我编辑了 statefulSet:
"volumes": [
{
"name": "XXX",
"persistentVolumeClaim": {
"claimName": "XXX"
}
}
添加了 "persistentVolumeClaim" 属性，删除了 pod，等待创建新的 pod。
我正在尝试 运行 使用 kubeless 的 kafka，但我收到此错误 pod has unbound immediate PersistentVolumeClaims。我已经使用 rook 和 ceph 创建了一个持久卷，并尝试将这个持久卷与 kubeless kafka 一起使用。但是，当我 运行 代码时，我得到 "pod has unbound persistent volume claims"
我做错了什么？

我的 minikube 中出现了同样的错误。忘记为我的 statefulSets 创建卷。
已创建 PVC。需要注意 storageClassName，检查 througt availiable（我在仪表盘上做了）。
{
"kind": "PersistentVolumeClaim",
"apiVersion": "v1",
"metadata": {
"name": "XXXX",
"namespace": "kube-public",
"labels": {
"kubeless": "XXXX"
}
},
"spec": {
"storageClassName": "hostpath",
"accessModes": [
"ReadWriteOnce"
],
"resources": {
"requests": {
"storage": "1Gi"
}
}
}
}
我得到了持久卷。 然后我编辑了 statefulSet:
"volumes": [
{
"name": "XXX",
"persistentVolumeClaim": {
"claimName": "XXX"
}
}
添加了 "persistentVolumeClaim" 属性，删除了 pod，等待创建新的 pod。
