It has enough information to retrieve secret in any namespace user string user is the rados user name. Default is admin. More info: https://examples.k8s.io/volumes/rbd/README.md#how-to-use-it 5.1.39. .spec.rbd.secretRef Description SecretReference represents a Secret Reference. It has enough information to retrieve secret in any namespace Type object Property Type Description name string name is unique within a namespace to reference a secret resource. namespace string namespace defines the space within which the secret name must be unique. 5.1.40. .spec.scaleIO Description ScaleIOPersistentVolumeSource represents a persistent ScaleIO volume Type object Required gateway system secretRef Property Type Description fsType string fsType is the filesystem type to mount. Must be a filesystem type supported by the host operating system. Ex. "ext4", "xfs", "ntfs". Default is "xfs" gateway string gateway is the host address of the ScaleIO API Gateway. protectionDomain string protectionDomain is the name of the ScaleIO Protection Domain for the configured storage. readOnly boolean readOnly defaults to false (read/write). ReadOnly here will force the ReadOnly setting in VolumeMounts. secretRef object SecretReference represents a Secret Reference. It has enough information to retrieve secret in any namespace sslEnabled boolean sslEnabled is the flag to enable/disable SSL communication with Gateway, default false storageMode string storageMode indicates whether the storage for a volume should be ThickProvisioned or ThinProvisioned. Default is ThinProvisioned. storagePool string storagePool is the ScaleIO Storage Pool associated with the protection domain. system string system is the name of the storage system as configured in ScaleIO. volumeName string volumeName is the name of a volume already created in the ScaleIO system that is associated with this volume source. 5.1.41. .spec.scaleIO.secretRef Description SecretReference represents a Secret Reference. It has enough information to retrieve secret in any namespace Type object Property Type Description name string name is unique within a namespace to reference a secret resource. namespace string namespace defines the space within which the secret name must be unique. 5.1.42. .spec.storageos Description Represents a StorageOS persistent volume resource. Type object Property Type Description fsType string fsType is the filesystem type to mount. Must be a filesystem type supported by the host operating system. Ex. "ext4", "xfs", "ntfs". Implicitly inferred to be "ext4" if unspecified. readOnly boolean readOnly defaults to false (read/write). ReadOnly here will force the ReadOnly setting in VolumeMounts. secretRef object ObjectReference contains enough information to let you inspect or modify the referred object. volumeName string volumeName is the human-readable name of the StorageOS volume. Volume names are only unique within a namespace. volumeNamespace string volumeNamespace specifies the scope of the volume within StorageOS. If no namespace is specified then the Pod's namespace will be used. This allows the Kubernetes name scoping to be mirrored within StorageOS for tighter integration. Set VolumeName to any name to override the default behaviour. Set to "default" if you are not using namespaces within StorageOS. Namespaces that do not pre-exist within StorageOS will be created. 5.1.43. .spec.storageos.secretRef Description ObjectReference contains enough information to let you inspect or modify the referred object. Type object Property Type Description apiVersion string API version of the referent. fieldPath string If referring to a piece of an object instead of an entire object, this string should contain a valid JSON/Go field access statement, such as desiredState.manifest.containers[2]. For example, if the object reference is to a container within a pod, this would take on a value like: "spec.containers{name}" (where "name" refers to the name of the container that triggered the event) or if no container name is specified "spec.containers[2]" (container with index 2 in this pod). This syntax is chosen only to have some well-defined way of referencing a part of an object. kind string Kind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds name string Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names namespace string Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/ resourceVersion string Specific resourceVersion to which this reference is made, if any. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency uid string UID of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#uids 5.1.44. .spec.vsphereVolume Description Represents a vSphere volume resource. Type object Required volumePath Property Type Description fsType string fsType is filesystem type to mount. Must be a filesystem type supported by the host operating system. Ex. "ext4", "xfs", "ntfs". Implicitly inferred to be "ext4" if unspecified. storagePolicyID string storagePolicyID is the storage Policy Based Management (SPBM) profile ID associated with the StoragePolicyName. storagePolicyName string storagePolicyName is the storage Policy Based Management (SPBM) profile name. volumePath string volumePath is the path that identifies vSphere volume vmdk 5.1.45. .status Description PersistentVolumeStatus is the current status of a persistent volume. Type object Property Type Description lastPhaseTransitionTime Time lastPhaseTransitionTime is the time the phase transitioned from one to another and automatically resets to current time everytime a volume phase transitions. This is a beta field and requires the PersistentVolumeLastPhaseTransitionTime feature to be enabled (enabled by default). message string message is a human-readable message indicating details about why the volume is in this state. phase string phase indicates if a volume is available, bound to a claim, or released by a claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#phase Possible enum values: - "Available" used for PersistentVolumes that are not yet bound Available volumes are held by the binder and matched to PersistentVolumeClaims - "Bound" used for PersistentVolumes that are bound - "Failed" used for PersistentVolumes that failed to be correctly recycled or deleted after being released from a claim - "Pending" used for PersistentVolumes that are not available - "Released" used for PersistentVolumes where the bound PersistentVolumeClaim was deleted released volumes must be recycled before becoming available again this phase is used by the persistent volume claim binder to signal to another process to reclaim the resource reason string reason is a brief CamelCase string that describes any failure and is meant for machine parsing and tidy display in the CLI. 5.2.
