是否可以将不同的Pod安装到本地持久卷的同一部分？

是否可以将不同的Pod安装到本地持久卷的同一部分？

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。
