type AWSCloudConfig 

type AWSCloudConfig struct {

		// TODO: Is there any use for this?  We can get it from the instance metadata service
		// Maybe if we're not running on AWS, e.g. bootstrap; for now it is not very useful
		Zone string

		KubernetesClusterTag string
	}
}

type AWSMetadata 

type AWSMetadata interface {

type VolumeOptions 

type VolumeOptions struct {
	CapacityMB int
}

type Volumes 

type Volumes interface {
	// Attach the disk to the specified instance
	// instanceName can be empty to mean "the instance on which we are running"
	// Returns the device (e.g. /dev/xvdf) where we attached the volume
	AttachDisk(instanceName string, volumeName string, readOnly bool) (string, error)
	// Detach the disk from the specified instance
	// instanceName can be empty to mean "the instance on which we are running"
