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
}
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.

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 sucess - 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 As the executables are called, the file-descriptors stdin, stdout, stderr remain open.
