func AssignQuota ¶ Uses

func AssignQuota(m mount.Interface, path string, poduid types.UID, bytes *resource.Quantity) error

AssignQuota -- assign a quota to the specified directory. AssignQuota chooses the quota ID based on the pod UID and path. If the pod UID is identical to another one known, it may (but presently doesn't) choose the same quota ID as other volumes in the pod. lint:ignore SA4009 poduid is overwritten by design, see comment below

func ClearQuota ¶ Uses

func ClearQuota(m mount.Interface, path string) error

ClearQuota -- remove the quota assigned to a directory

func GetConsumption ¶ Uses

func GetConsumption(path string) (*resource.Quantity, error)

GetConsumption -- retrieve the consumption (in bytes) of the directory

func GetInodes ¶ Uses

func GetInodes(path string) (*resource.Quantity, error)

GetInodes -- retrieve the number of inodes in use under the directory

func SupportsQuotas ¶ Uses

func SupportsQuotas(m mount.Interface, path string) (bool, error)

SupportsQuotas -- Does the path support quotas Cache the applier for paths that support quotas. For paths that don't, don't cache the result because nothing will clean it up. However, do cache the device->applier map; the number of devices is bounded.

type Interface ¶ Uses

type Interface interface {
    // Does the path provided support quotas, and if so, what types
    SupportsQuotas(m mount.Interface, path string) (bool, error)
    // Assign a quota (picked by the quota mechanism) to a path,
    // and return it.
    AssignQuota(m mount.Interface, path string, poduid types.UID, bytes *resource.Quantity) error

    // Get the quota-based storage consumption for the path
    GetConsumption(path string) (*resource.Quantity, error)

    // Get the quota-based inode consumption for the path
    GetInodes(path string) (*resource.Quantity, error)

    // Remove the quota from a path
    // Implementations may assume that any data covered by the
    // quota has already been removed.
    ClearQuota(m mount.Interface, path string) error
}

Interface -- quota interface
