Types

type DiskParameters

type DiskParameters struct {
	// Values: pd-standard OR pd-ssd
	// Default: pd-standard
	DiskType string
	// Values: "none", regional-pd
	// Default: "none"
	ReplicationType string
	// Values: {string}
	// Default: ""
	DiskEncryptionKMSKey string
	// Values: {map[string]string}
	// Default: ""
	Tags map[string]string
}

DiskParameters contains normalized and defaulted disk parameters

func ExtractAndDefaultParameters

func ExtractAndDefaultParameters(parameters map[string]string, driverName string) (DiskParameters, error)

ExtractAndDefaultParameters will take the relevant parameters from a map and put them into a well defined struct making sure to default unspecified fields

type VolumeLocks

type VolumeLocks struct {
	// contains filtered or unexported fields
}

VolumeLocks implements a map with atomic operations. It stores a set of all volume IDs with an ongoing operation.

func NewVolumeLocks

func NewVolumeLocks() *VolumeLocks

func (*VolumeLocks) Release

func (vl *VolumeLocks) Release(volumeID string)

func (*VolumeLocks) TryAcquire

func (vl *VolumeLocks) TryAcquire(volumeID string) bool

TryAcquire tries to acquire the lock for operating on volumeID and returns true if successful. If another operation is already using volumeID, returns false.
