Types ¶

type CIDRAllocator ¶

type CIDRAllocator interface {
	// AllocateOrOccupyCIDR looks at the given node, assigns it a valid
	// CIDR if it doesn't currently have one or mark the CIDR as used if
	// the node already have one.
	AllocateOrOccupyCIDR(node *v1.Node) error
	// ReleaseCIDR releases the CIDR of the removed node
	ReleaseCIDR(node *v1.Node) error
}

CIDRAllocator is an interface implemented by things that know how to allocate/occupy/recycle CIDR for nodes.

func NewCIDRRangeAllocator ¶

func NewCIDRRangeAllocator(client clientset.Interface, clusterCIDR *net.IPNet, serviceCIDR *net.IPNet, subNetMaskSize int, nodeList *v1.NodeList) (CIDRAllocator, error)

NewCIDRRangeAllocator returns a CIDRAllocator to allocate CIDR for node Caller must ensure subNetMaskSize is not less than cluster CIDR mask size. Caller must always pass in a list of existing nodes so the new allocator can initialize its CIDR map. NodeList is only nil in testing.

func NewCloudCIDRAllocator ¶

func NewCloudCIDRAllocator(
	client clientset.Interface,
	cloud cloudprovider.Interface) (ca CIDRAllocator, err error)

NewCloudCIDRAllocator creates a new cloud CIDR allocator.

type CIDRAllocatorType ¶

type CIDRAllocatorType string

CIDRAllocatorType is the type of the allocator to use.

const (
	// RangeAllocatorType is the allocator that uses an internal CIDR
	// range allocator to do node CIDR range allocations.
	RangeAllocatorType CIDRAllocatorType = "RangeAllocator"
	// CloudAllocatorType is the allocator that uses cloud platform
	// support to do node CIDR range allocations.
	CloudAllocatorType CIDRAllocatorType = "CloudAllocator"
)
