Types

type AutoAssignArgs

type AutoAssignArgs struct {
	HandleID string

	// A key/value mapping of metadata to store with the allocations.
	Attrs map[string]string

	Pool string
}

AutoAssignArgs defines the set of arguments for assigning one or more IP addresses.

type GetUtilizationArgs

type GetUtilizationArgs struct {
	// If specified, the pools whose utilization should be reported.  Each string here
	// can be a pool name or CIDR.  If not specified, this defaults to all pools.
	Pools []string
}

GetUtilizationArgs defines the set of arguments for requesting IP utilization.

type IPAMClient

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

IPAMClient implements Interface

func NewIPAMClient

func NewIPAMClient(client kubesphere.Interface, typeStr string) IPAMClient

NewIPAMClient returns a new IPAMClient, which implements Interface.

func (IPAMClient) AutoAssign

func (c IPAMClient) AutoAssign(args AutoAssignArgs) (*current.Result, error)

AutoAssign automatically assigns one or more IP addresses as specified by the provided AutoAssignArgs. AutoAssign returns the list of the assigned IPv4 addresses, and the list of the assigned IPv6 addresses.

In case of error, returns the IPs allocated so far along with the error.

func (IPAMClient) DeleteBlock

func (c IPAMClient) DeleteBlock(b *v1alpha1.IPAMBlock) error

DeleteBlock deletes the given block.

func (IPAMClient) GetUtilization

func (c IPAMClient) GetUtilization(args GetUtilizationArgs) ([]*PoolUtilization, error)

GetUtilization returns IP utilization info for the specified pools, or for all pools.

func (IPAMClient) ListBlocks

func (c IPAMClient) ListBlocks(pool string) ([]v1alpha1.IPAMBlock, error)

func (IPAMClient) ReleaseByHandle

func (c IPAMClient) ReleaseByHandle(handleID string) error

ReleaseByHandle releases all IP addresses that have been assigned using the provided handle.

type Interface

type Interface interface {
	// AutoAssign automatically assigns one or more IP addresses as specified by the
	// provided AutoAssignArgs.  AutoAssign returns the list of the assigned IPv4 addresses,
	// and the list of the assigned IPv6 addresses in IPNet format.
	// The returned IPNet represents the allocation block from which the IP was allocated,
	// which is useful for dataplanes that need to know the subnet (such as Windows).
	//
	// In case of error, returns the IPs allocated so far along with the error.
	AutoAssign(args AutoAssignArgs) (*current.Result, error)

	// ReleaseByHandle releases all IP addresses that have been assigned
	// using the provided handle.  Returns an error if no addresses
	// are assigned with the given handle.
	ReleaseByHandle(handleID string) error

	GetUtilization(args GetUtilizationArgs) ([]*PoolUtilization, error)
}

ipam.Interface has methods to perform IP address management.

type PoolAccessorInterface

type PoolAccessorInterface interface {
	// contains filtered or unexported methods
}

Interface used to access the enabled IPPools.

type PoolUtilization

type PoolUtilization struct {
	// This pool's name.
	Name string

	// Number of possible IPs in this block.
	Capacity int

	// Number of available IPs in this block.
	Unallocated int

	Allocate int

	Reserved int
}

PoolUtilization reports IP utilization for a single IP pool.
