Functions

func NewFakeHost

func NewFakeHost(kubeClient client.Interface) *fakeNetworkHost

func UnescapePluginName

func UnescapePluginName(in string) string

Types

type Host

type Host interface {
	// Get the pod structure by its name, namespace
	GetPodByName(namespace, name string) (*api.Pod, bool)

	// GetKubeClient returns a client interface
	GetKubeClient() client.Interface
}

Host is an interface that plugins can use to access the kubelet.

type NetworkPlugin

type NetworkPlugin interface {
	// Init initializes the plugin.  This will be called exactly once
	// before any other methods are called.
	Init(host Host) error

	// Name returns the plugin's name. This will be used when searching
	// for a plugin by name, e.g.
	Name() string

	// SetUpPod is the method called after the infra container of
	// the pod has been created but before the other containers of the
	// pod are launched.
	SetUpPod(namespace string, name string, podInfraContainerID kubeletTypes.DockerID) error

	// TearDownPod is the method called before a pod's infra container will be deleted
	TearDownPod(namespace string, name string, podInfraContainerID kubeletTypes.DockerID) error

	// Status is the method called to obtain the ipv4 or ipv6 addresses of the container
	Status(namespace string, name string, podInfraContainerID kubeletTypes.DockerID) (*PodNetworkStatus, error)
}

Plugin is an interface to network plugins for the kubelet

func InitNetworkPlugin

func InitNetworkPlugin(plugins []NetworkPlugin, networkPluginName string, host Host) (NetworkPlugin, error)

InitNetworkPlugin inits the plugin that matches networkPluginName. Plugins must have unique names.

type PodNetworkStatus

type PodNetworkStatus struct {
	api.TypeMeta `json:",inline"`

	// IP is the primary ipv4/ipv6 address of the pod. Among other things it is the address that -
	//   - kube expects to be reachable across the cluster
	//   - service endpoints are constructed with
	//   - will be reported in the PodStatus.PodIP field (will override the IP reported by docker)
	IP net.IP `json:"ip" description:"Primary IP address of the pod"`
}

PodNetworkStatus stores the network status of a pod (currently just the primary IP address) This struct represents version "v1"
