CloudConfig wraps the settings for the AWS cloud provider. NOTE: Cloud config files should follow the same Kubernetes deprecation policy as flags or CLIs. Config fields should not change behavior in incompatible ways and should be deprecated for at least 2 release prior to removing. See https://kubernetes.io/docs/reference/using-api/deprecation-policy/#deprecating-a-flag-or-cli for more details.

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)

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)
	// Detach a volume from an instance it is attached to
	DetachVolume(request *ec2.DetachVolumeInput) (resp *ec2.VolumeAttachment, err error)
	// Lists volumes
	DescribeVolumes(request *ec2.DescribeVolumesInput) ([]*ec2.Volume, error)
	// Create an EBS volume
	CreateVolume(request *ec2.CreateVolumeInput) (resp *ec2.Volume, err error)
	// Delete an EBS volume
	DeleteVolume(*ec2.DeleteVolumeInput) (*ec2.DeleteVolumeOutput, error)

type VolumeOptions 

type VolumeOptions struct {
	CapacityGB       int
	Tags             map[string]string
	VolumeType       string
	AvailabilityZone string
	// IOPSPerGB x CapacityGB will give total IOPS of the volume to create.
	// Calculated total IOPS will be capped at MaxTotalIOPS.
	IOPSPerGB int
	Encrypted bool
	// fully qualified resource name to the key to use for encryption.
	// example: arn:aws:kms:us-east-1:012345678910:key/abcd1234-a123-456a-a12b-a123b4cd56ef
	KmsKeyID string
}

VolumeOptions specifies capacity and tags for a volume.

type Volumes 

type Volumes interface {
	// Attach the disk to the node with the specified NodeName
	// nodeName 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(diskName KubernetesVolumeID, nodeName types.NodeName) (string, error)
	// Detach the disk from the node with the specified NodeName
	// nodeName can be empty to mean "the instance on which we are running"
	// Returns the device where the volume was attached
	DetachDisk(diskName KubernetesVolumeID, nodeName types.NodeName) (string, error)

	// Create a volume with the specified options
	CreateDisk(volumeOptions *VolumeOptions) (volumeName KubernetesVolumeID, err error)
	// Delete the specified volume
	// Returns true iff the volume was deleted
	// If the was not found, returns (false, nil)
	DeleteDisk(volumeName KubernetesVolumeID) (bool, error)

	// Get labels to apply to volume on creation
	GetVolumeLabels(volumeName KubernetesVolumeID) (map[string]string, error)

	// Get volume's disk path from volume name
	// return the device path where the volume is attached
	GetDiskPath(volumeName KubernetesVolumeID) (string, error)

	// Check if the volume is already attached to the node with the specified NodeName
	DiskIsAttached(diskName KubernetesVolumeID, nodeName types.NodeName) (bool, error)

	// Check if disks specified in argument map are still attached to their respective nodes.
	DisksAreAttached(map[types.NodeName][]KubernetesVolumeID) (map[types.NodeName]map[KubernetesVolumeID]bool, error)

	// Expand the disk to new size
	ResizeDisk(diskName KubernetesVolumeID, oldSize resource.Quantity, newSize resource.Quantity) (resource.Quantity, error)
}

Volumes is an interface for managing cloud-provisioned volumes TODO: Allow other clouds to implement this
