		//This flag disables the automatic ingress creation. It requires that the user

type CrossRequestRetryDelay 

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

CrossRequestRetryDelay inserts delays before AWS calls, when we are observing RequestLimitExceeded errors Note that we share a CrossRequestRetryDelay across multiple AWS requests; this is a process-wide back-off, whereas the aws-sdk-go implements a per-request exponential backoff/retry

func NewCrossRequestRetryDelay 

func NewCrossRequestRetryDelay() *CrossRequestRetryDelay

NewCrossRequestRetryDelay creates a new CrossRequestRetryDelay

func (*CrossRequestRetryDelay) AfterRetry 

func (c *CrossRequestRetryDelay) AfterRetry(r *request.Request)

AfterRetry is added to the AfterRetry chain; called after any error

func (*CrossRequestRetryDelay) BeforeSign 

func (c *CrossRequestRetryDelay) BeforeSign(r *request.Request)

BeforeSign is added to the Sign chain; called before each request

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()
}

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.

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/.

func NewDeviceAllocator 

func NewDeviceAllocator() DeviceAllocator

NewDeviceAllocator 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 EBSVolumeID 

type EBSVolumeID string

EBSVolumeID represents the ID of the volume in the AWS API, e.g. vol-12345678 The "traditional" format is "vol-12345678" A new longer format is also being introduced: "vol-12345678abcdef01" We should not assume anything about the length or format, though it seems reasonable to assume that volumes will continue to start with "vol-".

type EC2 

type EC2 interface {
	// Query EC2 for instances matching the filter
	DescribeInstances(request *ec2.DescribeInstancesInput) ([]*ec2.Instance, error)

	// Attach a volume to an instance
	AttachVolume(*ec2.AttachVolumeInput) (*ec2.VolumeAttachment, error)

	DescribeVolumes(request *ec2.DescribeVolumesInput) ([]*ec2.Volume, error)
	// Create an EBS volume
	CreateVolume(request *ec2.CreateVolumeInput) (resp *ec2.Volume, err error)

	DescribeVpcs(input *ec2.DescribeVpcsInput) (*ec2.DescribeVpcsOutput, error)
}

EC2 is an abstraction over AWS', to allow mocking/other implementations Note that the DescribeX functions return a list, so callers don't need to deal with paging TODO: Should we rename this to AWS (EBS & ELB are not technically part of EC2)

type EC2Metadata 

type EC2Metadata interface {
	// Query the EC2 metadata service (used to discover instance-id etc)
	GetMetadata(path string) (string, error)
}
