Functions

func CreatePortBinding

func CreatePortBinding(hostPort int, hostIP string) []nat.PortBinding

CreatePortBinding takes port (int) and IP (string) and creates an array of portbinding structs

func Device

func Device(d *configs.Device) spec.LinuxDevice

Device transforms a libcontainer configs.Device to a specs.LinuxDevice object.

func ExposedPorts

func ExposedPorts(expose, publish []string, publishAll bool, imageExposedPorts map[string]struct{}) (map[nat.Port][]nat.PortBinding, error)

ExposedPorts parses user and image ports and returns binding information

func IsNS added in v0.7.4

func IsNS(s string) bool

IsNS returns if the specified string has a ns: prefix

func IsPod added in v0.8.4

func IsPod(s string) bool

IsPod returns if the specified string is pod
