Functions

func CreateNetNS

func CreateNetNS(name string) error

func DestroyNetNS

func DestroyNetNS(name string) error

func GetPodIP

func GetPodIP(result *cnicurrent.Result) string

GetPodIP retrieves the IP address of the pod as a string. It uses the first IPv4 address if finds. If it fails to determine the pod IP or the result argument is nil, it returns an empty string.

func PodNetNSPath

Types

type CNIClient

type CNIClient interface {
	// AddSandboxToNetwork adds a pod sandbox to the CNI network
	AddSandboxToNetwork(podId, podName, podNs string) (*cnicurrent.Result, error)
	// RemoveSandboxFromNetwork removes a pod sandbox from the CNI network
	RemoveSandboxFromNetwork(podId, podName, podNs string) error
	// GetDummyNetwork creates a dummy network using CNI plugin.
	// It's used for making a dummy gateway for Calico CNI plugin
	GetDummyNetwork() (*cnicurrent.Result, string, error)
}
