Types ¶

type IPAMClaimReconciler ¶

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

IPAMClaimReconciler acts on IPAMClaim events handed off by the cluster network controller and allocates or releases IPs for IPAMClaims.

func NewIPAMClaimReconciler ¶

func NewIPAMClaimReconciler(kube kube.InterfaceOVN, netConfig util.NetInfo, lister ipamclaimslister.IPAMClaimLister) *IPAMClaimReconciler

NewIPAMClaimReconciler builds a new PersistentIPsAllocator

func (*IPAMClaimReconciler) FindIPAMClaim ¶

func (icr *IPAMClaimReconciler) FindIPAMClaim(claimName string, namespace string) (*ipamclaimsapi.IPAMClaim, error)

func (*IPAMClaimReconciler) Reconcile ¶

func (icr *IPAMClaimReconciler) Reconcile(
	oldIPAMClaim *ipamclaimsapi.IPAMClaim,
	newIPAMClaim *ipamclaimsapi.IPAMClaim,
	ipReleaser IPReleaser,
) error

Reconcile updates an IPAMClaim with the IP addresses allocated to the pod's interface

func (*IPAMClaimReconciler) Sync ¶

func (icr *IPAMClaimReconciler) Sync(objs []interface{}, ipAllocator IPAllocator) error

Sync initializes the IPs allocator with the IPAMClaims already existing on the cluster. For live pods, therse are already allocated, so no error will be thrown (e.g. we ignore the `ipam.IsErrAllocated` error

type IPAllocator ¶

type IPAllocator interface {
	AllocateIPs(ips []*net.IPNet) error
}

type IPReleaser ¶

type IPReleaser interface {
	ReleaseIPs(ips []*net.IPNet) error
}

type PersistentAllocations ¶

type PersistentAllocations interface {
	FindIPAMClaim(claimName string, namespace string) (*ipamclaimsapi.IPAMClaim, error)

	Reconcile(oldIPAMClaim *ipamclaimsapi.IPAMClaim, newIPAMClaim *ipamclaimsapi.IPAMClaim, ipReleaser IPReleaser) error
}
