我能够实现上述情况，您需要在pv中使用“ claimRef”来绑定PVC。请看看下面的pv json和statefulset json
PV-0.json
{
"kind": "PersistentVolume",
"apiVersion": "v1",
"Metadata": {
"name": "pv-data-vol-0",
"labels": {
"type": "local"
}
},
"spec": {
"capacity": {
"storage": "10Gi"
},
"accessModes": [
"ReadWriteOnce"
],
"storageClassName": "local-storage",
"local": {
"path": "/prafull/data/pv-0"
},
"claimRef": {
"namespace": "default",
"name": "data-test-sf-0"
},
"nodeAffinity": {
"required": {
"nodeSelectorTerms": [
{
"matchExpressions": [
{
"key": "kubernetes.io/hostname",
"operator": "In",
"values": [
"ip-10-0-1-46.ec2.internal"
]
}
]
}
]
}
}
}
}
PV-1.json
{
"kind": "PersistentVolume",
"apiVersion": "v1",
"Metadata": {
"name": "pv-data-vol-1",
"labels": {
"type": "local"
}
},
"spec": {
"capacity": {
"storage": "10Gi"
},
"accessModes": [
"ReadWriteOnce"
],
"storageClassName": "local-storage",
"local": {
"path": "/prafull/data/pv-1"
},
"claimRef": {
"namespace": "default",
"name": "data-test-sf-1"
},
"nodeAffinity": {
"required": {
"nodeSelectorTerms": [
{
"matchExpressions": [
{
"key": "kubernetes.io/hostname",
"operator": "In",
"values": [
"ip-10-0-1-46.ec2.internal"
]
}
]
}
]
}
}
}
}
Statefulset.json
{
"kind": "StatefulSet",
"apiVersion": "apps/v1beta1",
"Metadata": {
"name": "test-sf",
"labels": {
"state": "test-sf"
}
},
"spec": {
"replicas": 2,
"template": {
"Metadata": {
"labels": {
"app": "test-sf"
},
"annotations": {
"pod.alpha.kubernetes.io/initialized": "true"
}
}
...
...
},
"volumeClaimTemplates": [
{
"Metadata": {
"name": "data"
},
"spec": {
"accessModes": [
"ReadWriteOnce"
],
"storageClassName": "local-storage",
"resources": {
"requests": {
"storage": "10Gi"
}
}
}
}
]
}
}
将创建两个Pod，分别创建test-sf-0和test-sf-1，依次创建两个PVC数据-test-sf-0和data-test- sf-1，它们将绑定到PV-0和Pv-1。因此，test-sf-0将写入PV-0中指定的位置，而test- sf-1将写入PV-1中指定的位置。希望这可以帮助。
