Functions

func GetAllNetworkConfigList

func GetAllNetworkConfigList(cniPath *CNIPath) ([]*libcni.NetworkConfigList, error)

GetAllNetworkConfigList lists configured networks in configuration path directory provided by cniPath

Types

type CNIPath

type CNIPath struct {
	Conf   string
	Plugin string
}

CNIPath contains path to CNI configuration directory and path to executable CNI plugins directory

type PortMapEntry

type PortMapEntry struct {
	HostPort      int    `json:"hostPort"`
	ContainerPort int    `json:"containerPort"`
	Protocol      string `json:"protocol"`
	HostIP        string `json:"hostIP,omitempty"`
}

PortMapEntry describes a port mapping between host and container

type Setup

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

Setup contains network installation setup

func NewSetup

func NewSetup(networks []string, containerID string, netNS string, cniPath *CNIPath) (*Setup, error)

NewSetup creates and returns a network setup to configure, add and remove network interfaces in container

func NewSetupFromConfig

func NewSetupFromConfig(networkConfList []*libcni.NetworkConfigList, containerID string, netNS string, cniPath *CNIPath) (*Setup, error)
