Types

type K8SManager

type K8SManager struct {
	// contains filtered or unexported fields
}

K8SManager implements the plugin for the Kubernetes cluster manager.

func NewK8sManager

func NewK8sManager(
	configPath string,
	podEventCh chan<- *scalar.PodEvent,
	hostEventCh chan<- *scalar.HostEvent,
) (*K8SManager, error)

NewK8sManager returns a new instance of K8SManager

func (*K8SManager) AckPodEvent

func (k *K8SManager) AckPodEvent(ctx context.Context, event *scalar.PodEvent)

AckPodEvent is relevant to Mesos. For K8s for now, this is a noop. We could use some smarts here if we decide to write the resource version to DB after the event has been acknowledged by both JM and RM

func (*K8SManager) KillPod

func (k *K8SManager) KillPod(podID string) error

KillPod stops and deletes the given pod

func (*K8SManager) LaunchPod

func (k *K8SManager) LaunchPod(
	podSpec *pbpod.PodSpec,
	podID, hostname string,
) error

LaunchPod creates a pod object, binds it to the node specified by hostname.

func (*K8SManager) ReconcileHosts

func (k *K8SManager) ReconcileHosts() ([]*scalar.HostInfo, error)

ReconcileHosts lists all nodes on the API server and converts them into host infos.

func (*K8SManager) Start

func (k *K8SManager) Start() error

Start starts the k8s manager plugin

func (*K8SManager) Stop

func (k *K8SManager) Stop()
