Functions ¶

func IsPortOpen ¶ added in v0.5.0

func IsPortOpen(port int) bool

IsPortOpen checks if the TCP port is open/used. It returns true if the port is open/used, otherwise false.

func PublicIP ¶

func PublicIP() (string, error)

Types ¶

type InterfaceAddr ¶ added in v0.5.0

type InterfaceAddr struct {
	Iface net.Interface
	Addr  netip.Addr
}

InterfaceAddr represents a network interface and its associated InterfaceAddr address.

func DefaultRouteHostIPv4 ¶ added in v0.13.2

func DefaultRouteHostIPv4() (InterfaceAddr, error)

DefaultRouteHostIPv4 returns the IPv4 address kubelet would choose as the node InternalIP when no address is configured: the global unicast address on the interface holding the default route (k8s.io/apimachinery ChooseHostInterface). On hosts without /proc/net/route (e.g., macOS), ChooseHostInterface falls back to the first up, non-loopback interface with a global unicast address.

The address is not required to be RFC1918; bare-metal hosts commonly use non-RFC1918 internal ranges (e.g., 7.0.0.0/8) for the host network.

type InterfaceAddrs ¶ added in v0.5.0

type InterfaceAddrs []InterfaceAddr

InterfaceAddrs is a slice of InterfaceAddr.

func GetPrivateIPs ¶ added in v0.5.0

func GetPrivateIPs(opts ...OpOption) (InterfaceAddrs, error)

GetPrivateIPs finds private IP addresses using an optional interface filter. It returns a slice of IP structs, each containing interface and address information.

func (InterfaceAddrs) RenderTable ¶ added in v0.5.0

func (addrs InterfaceAddrs) RenderTable(wr io.Writer)

RenderTable renders the InterfaceAddrs as a table.

type Op ¶ added in v0.5.0

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

type OpOption ¶ added in v0.5.0

type OpOption func(*Op)

func WithPrefixesToSkip ¶ added in v0.5.0

func WithPrefixesToSkip(prefixes ...string) OpOption

func WithSuffixesToSkip ¶ added in v0.5.0

func WithSuffixesToSkip(suffixes ...string) OpOption
