Functions

func AutoDetectCIDR

func AutoDetectCIDR(method string, version int) (*net.IPNet, error)

AutoDetectCIDR auto-detects the IP and Network using the requested detection method.

func CheckCalicoMethod

func CheckCalicoMethod(method string) bool

func CheckMethod

func CheckMethod(method string) bool

Types

type Interface

type Interface struct {
	Name  string
	Cidrs []net.IPNet
}

Interface contains details about an interface on the host.

func FilteredEnumeration

func FilteredEnumeration(incl, excl []string, cidrs []net.IPNet, version int) (*Interface, *net.IPNet, error)

FilteredEnumeration performs basic IP and IPNetwork discovery by enumerating all interfaces and filtering in/out based on the supplied filter regex.

The incl and excl slice of regex strings may be nil.

func GetInterfaces

func GetInterfaces(includeRegexes []string, excludeRegexes []string, version int) ([]Interface, error)

GetInterfaces returns a list of all interfaces, skipping any interfaces whose name matches any of the exclusion list regexes, and including those on the inclusion list.
