Types ¶

type IPLease ¶ added in v0.2.0

type IPLease struct {
	IP         string
	Subnet     string
	Reserved   bool
	ReleasedAt *time.Time
}

IPLease represents an IP lease record from the database.

type LeaseFilter ¶ added in v0.2.0

type LeaseFilter struct {
	Subnet       string
	ReservedOnly bool
	ReleasedOnly bool
}

LeaseFilter specifies filters for listing IP leases.

type NetDB ¶

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

func New ¶

func New(path string) (*NetDB, error)

func (*NetDB) Close ¶

func (n *NetDB) Close() error

func (*NetDB) ForceReleaseAll ¶ added in v0.2.0

func (n *NetDB) ForceReleaseAll() (int, error)

ForceReleaseAll releases all reserved IPs.

func (*NetDB) ForceReleaseIP ¶ added in v0.2.0

func (n *NetDB) ForceReleaseIP(ip string) (bool, error)

ForceReleaseIP releases a specific IP address regardless of its current state.

func (*NetDB) ForceReleaseIPs ¶ added in v0.2.0

func (n *NetDB) ForceReleaseIPs(ips []string) error

ForceReleaseIPs releases a specific set of IPs in a single transaction.

func (*NetDB) ForceReleaseSubnet ¶ added in v0.2.0

func (n *NetDB) ForceReleaseSubnet(subnet string) (int, error)

ForceReleaseSubnet releases all reserved IPs in a subnet.

func (*NetDB) GetLeasedSubnet ¶ added in v0.7.0

func (n *NetDB) GetLeasedSubnet() (netip.Prefix, error)

GetLeasedSubnet returns the previously persisted flannel subnet lease, if any. Returns an invalid prefix with nil error if no lease has been saved.

func (*NetDB) GetReservedIPs ¶ added in v0.2.0

func (n *NetDB) GetReservedIPs(subnet string) ([]string, error)

GetReservedIPs returns all reserved IP addresses, optionally filtered by subnet.

func (*NetDB) GetSubnetStatus ¶ added in v0.2.0

func (n *NetDB) GetSubnetStatus() ([]SubnetStatus, error)

GetSubnetStatus returns utilization statistics for all subnets.

func (*NetDB) ListLeases ¶ added in v0.2.0

func (n *NetDB) ListLeases(filter LeaseFilter) ([]IPLease, error)

ListLeases returns IP leases matching the given filter.

func (*NetDB) ReleaseInterface ¶

func (n *NetDB) ReleaseInterface(name string) error

func (*NetDB) ReserveInterface ¶

func (n *NetDB) ReserveInterface(prefix string) (string, error)

func (*NetDB) SetLeasedSubnet ¶ added in v0.7.0

func (n *NetDB) SetLeasedSubnet(prefix netip.Prefix) error

SetLeasedSubnet persists the flannel subnet lease so it can be reused on restart.

func (*NetDB) Subnet ¶

func (n *NetDB) Subnet(cidr string) (*Subnet, error)

type Subnet ¶

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

func (*Subnet) Prefix ¶

func (s *Subnet) Prefix() netip.Prefix

func (*Subnet) Release ¶

func (s *Subnet) Release(prefix netip.Prefix) error

func (*Subnet) ReleaseAddr ¶

func (s *Subnet) ReleaseAddr(addr netip.Addr) error

func (*Subnet) ReleaseSubnet ¶

func (s *Subnet) ReleaseSubnet(prefix netip.Prefix) error

func (*Subnet) Reserve ¶

func (s *Subnet) Reserve() (netip.Prefix, error)

func (*Subnet) ReserveSpecificAddr ¶ added in v0.7.0

func (s *Subnet) ReserveSpecificAddr(addr netip.Addr) error

ReserveSpecificAddr reserves a specific IP address in the subnet. This is idempotent: it succeeds whether the IP is new, already reserved, or was released. Returns an error if the address is not a usable host address within the subnet.

func (*Subnet) ReserveSubnet ¶

func (s *Subnet) ReserveSubnet(bits int, identifier string) (*Subnet, error)

func (*Subnet) Router ¶

func (s *Subnet) Router() netip.Prefix

type SubnetStatus ¶ added in v0.2.0

type SubnetStatus struct {
	Subnet   string
	Total    int
	Reserved int
	Released int
	Capacity int
}

SubnetStatus contains utilization statistics for a subnet.
