		Zone string

		// The AWS VPC flag enables the possibility to run the master components
		// on a different aws account, on a different cloud provider or on-premises.
		// If the flag is set also the KubernetesClusterTag must be provided
		VPC string
		// SubnetID enables using a specific subnet to use for ELB's

type DeviceAllocator

type DeviceAllocator interface {
	// GetNext returns a free device name or error when there is no free device
	// name. Only the device suffix is returned, e.g. "ba" for "/dev/xvdba".
	// It's up to the called to add appropriate "/dev/sd" or "/dev/xvd" prefix.
	GetNext(existingDevices ExistingDevices) (mountDevice, error)

	// Deprioritize the device so as it can't be used immediately again
	Deprioritize(mountDevice)

	// Lock the deviceAllocator
	Lock()

	// Unlock the deviceAllocator
	Unlock()
}

On AWS, we should assign new (not yet used) device names to attached volumes. If we reuse a previously used name, we may get the volume "attaching" forever, see https://aws.amazon.com/premiumsupport/knowledge-center/ebs-stuck-attaching/. DeviceAllocator finds available device name, taking into account already assigned device names from ExistingDevices map. It tries to find the next device name to the previously assigned one (from previous DeviceAllocator call), so all available device names are used eventually and it minimizes device name reuse. All these allocations are in-memory, nothing is written to / read from /dev directory.

func NewDeviceAllocator

func NewDeviceAllocator() DeviceAllocator

Allocates device names according to scheme ba..bz, ca..cz it moves along the ring and always picks next device until device list is exhausted.

type ExistingDevices

type ExistingDevices map[mountDevice]awsVolumeID

ExistingDevices is a map of assigned devices. Presence of a key with a device name in the map means that the device is allocated. Value is irrelevant and can be used for anything that DeviceAllocator user wants. Only the relevant part of device name should be in the map, e.g. "ba" for "/dev/xvdba".
