Chapter 7. StorageClass [storage.k8s.io/v1] Description StorageClass describes the parameters for a class of storage for which PersistentVolumes can be dynamically provisioned. StorageClasses are non-namespaced; the name of the storage class according to etcd is in ObjectMeta.Name. Type object Required provisioner 7.1. Specification Property Type Description allowVolumeExpansion boolean allowVolumeExpansion shows whether the storage class allow volume expand. allowedTopologies array (TopologySelectorTerm) allowedTopologies restrict the node topologies where volumes can be dynamically provisioned. Each volume plugin defines its own supported topology specifications. An empty TopologySelectorTerm list means there is no topology restriction. This field is only honored by servers that enable the VolumeScheduling feature. apiVersion 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. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources kind 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. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata mountOptions array (string) mountOptions controls the mountOptions for dynamically provisioned PersistentVolumes of this storage class. e.g. ["ro", "soft"]. Not validated - mount of the PVs will simply fail if one is invalid. parameters object (string) parameters holds the parameters for the provisioner that should create volumes of this storage class. provisioner string provisioner indicates the type of the provisioner. reclaimPolicy string reclaimPolicy controls the reclaimPolicy for dynamically provisioned PersistentVolumes of this storage class. Defaults to Delete. Possible enum values: - "Delete" means the volume will be deleted from Kubernetes on release from its claim. The volume plugin must support Deletion. - "Recycle" means the volume will be recycled back into the pool of unbound persistent volumes on release from its claim. The volume plugin must support Recycling. - "Retain" means the volume will be left in its current phase (Released) for manual reclamation by the administrator. The default policy is Retain. volumeBindingMode string volumeBindingMode indicates how PersistentVolumeClaims should be provisioned and bound. When unset, VolumeBindingImmediate is used. This field is only honored by servers that enable the VolumeScheduling feature. Possible enum values: - "Immediate" indicates that PersistentVolumeClaims should be immediately provisioned and bound. This is the default mode. - "WaitForFirstConsumer" indicates that PersistentVolumeClaims should not be provisioned and bound until the first Pod is created that references the PeristentVolumeClaim. The volume provisioning and binding will occur during Pod scheduing. 7.2. API endpoints The following API endpoints are available: /apis/storage.k8s.io/v1/storageclasses DELETE : delete collection of StorageClass GET : list or watch objects of kind StorageClass POST : create a StorageClass /apis/storage.k8s.io/v1/watch/storageclasses GET : watch individual changes to a list of StorageClass. deprecated: use the 'watch' parameter with a list operation instead. /apis/storage.k8s.io/v1/storageclasses/{name} DELETE : delete a StorageClass GET : read the specified StorageClass PATCH : partially update the specified StorageClass PUT : replace the specified StorageClass /apis/storage.k8s.io/v1/watch/storageclasses/{name} GET : watch changes to an object of kind StorageClass. deprecated: use the 'watch' parameter with a list operation instead, filtered to a single item with the 'fieldSelector' parameter. 7.2.1. /apis/storage.k8s.io/v1/storageclasses HTTP method DELETE Description delete collection of StorageClass Table 7.1. Query parameters Parameter Type Description dryRun string When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed Table 7.2. HTTP responses HTTP code Reponse body 200 - OK Status schema 401 - Unauthorized Empty HTTP method GET Description list or watch objects of kind StorageClass Table 7.3. HTTP responses HTTP code Reponse body 200 - OK StorageClassList schema 401 - Unauthorized Empty HTTP method POST Description create a StorageClass Table 7.4. Query parameters Parameter Type Description dryRun string When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed fieldValidation string fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. Table 7.5. Body parameters Parameter Type Description body StorageClass schema Table 7.6.
