请求消息
请求参数：
参数 |
是否必选 |
参数类型 |
描述 |
|---|---|---|---|
apiVersion |
Yes |
String |
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. |
kind |
Yes |
String |
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. |
metadata |
Yes |
metadata object |
Standard object's metadata. |
spec |
Yes |
spec object |
Spec defines the desired characteristics of a volume requested by a pod author. |
status |
No |
status object |
Status represents the current information/status of a persistent volume claim. Read-only. |
参数 |
是否必选 |
参数类型 |
描述 |
|---|---|---|---|
accessModes |
No |
Array of strings |
AccessModes contains the actual access modes the volume backing the PVC has. |
capacity |
No |
Object |
Represents the actual resources of the underlying volume. |
phase |
No |
String |
Phase represents the current phase of PersistentVolumeClaim. |
参数 |
是否必选 |
参数类型 |
描述 |
|---|---|---|---|
volumeName |
No |
String |
VolumeName is the binding reference to the PersistentVolume backing this claim. |
accessModes |
Yes |
Array of strings |
AccessModes contains the desired access modes the volume should have. A volume can only be mounted using one access mode at a time, even if it supports many. |
resources |
Yes |
resources object |
Resources represents the minimum resources the volume should have. |
selector |
No |
selector object |
A label query over volumes to consider for binding. |
storageClassName |
No |
String |
Name of the StorageClass required by the claim. The cluster of v1.15 or later which use CCE SCI everest should fill in this filed. For EVS, set "csi-disk". For SFS, set "csi-nas". For OBS, set "csi-obs". For SFS-Turbo, set "csi-sfsturbo". |
参数 |
是否必选 |
参数类型 |
描述 |
|---|---|---|---|
limits |
No |
Object |
Limits describes the maximum amount of compute resources allowed. 说明：
Parameter limits is invalid. |
requests |
No |
Object |
Requests describes the minimum amount of compute resources required. If Requests is omitted for a container, it defaults to Limits if that is explicitly specified, otherwise to an implementation-defined value. 说明：
Except parameter storage, the other parameters (such as CPU and memory) are invalid. |
参数 |
是否必选 |
参数类型 |
描述 |
|---|---|---|---|
matchExpressions |
No |
matchExpressions object |
MatchExpressions is a list of label selector requirements. The requirements are ANDed. |
matchLabels |
No |
Object |
MatchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed. |
参数 |
是否必选 |
参数类型 |
描述 |
|---|---|---|---|
key |
No |
String |
Key is the label key that the selector applies to. |
operator |
No |
String |
Operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist. |
values |
No |
Array of strings |
Values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch. |
