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 ¶ added in v1.1.1
type PodNetworkStatus struct { unversioned.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"

Package exec scans and loads networking plugins that are installed under /usr/libexec/kubernetes/kubelet-plugins/net/exec/ The layout convention for a plugin is: plugin-name/ (plugins have to be directories first) plugin-name/plugin-name (executable that will be called out, see Vendoring Note for more nuances) plugin-name/<other-files> where, 'executable' has the following requirements: - should have exec permissions - should give non-zero exit code on failure, and zero on success - the arguments will be <action> <pod_namespace> <pod_name> <docker_id_of_infra_container> whereupon, <action> will be one of: - init, called when the kubelet loads the plugin - setup, called after the infra container of a pod is created, but before other containers of the pod are created - teardown, called before the pod infra container is killed - status, called at regular intervals and is supposed to return a json formatted output indicating the pod's IPAddress(v4/v6).
