Types ¶

type Config ¶

type Config struct {
	Updates              chan<- kubetypes.PodUpdate // to send pod config updates to the kubelet
	APIClient            *client.Client
	Docker               dockertools.DockerInterface
	ShutdownAlert        func()
	SuicideTimeout       time.Duration
	KubeletFinished      <-chan struct{} // signals that kubelet Run() died
	ExitFunc             func(int)
	PodStatusFunc        func(*api.Pod) (*api.PodStatus, error)
	StaticPodsConfigPath string
	PodLW                cache.ListerWatcher // mandatory, otherwise initialiation will panic
	LaunchGracePeriod    time.Duration
	NodeInfos            chan<- NodeInfo
}

type Executor ¶

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

KubernetesExecutor is an mesos executor that runs pods in a minion machine.

func New ¶

func New(config Config) *Executor

New creates a new kubernetes executor.

func (*Executor) Disconnected ¶

func (k *Executor) Disconnected(driver bindings.ExecutorDriver)

Disconnected is called when the executor is disconnected from the slave.

func (*Executor) Error ¶

func (k *Executor) Error(driver bindings.ExecutorDriver, message string)

Error is called when some error happens.

func (*Executor) FrameworkMessage ¶

func (k *Executor) FrameworkMessage(driver bindings.ExecutorDriver, message string)

FrameworkMessage is called when the framework sends some message to the executor

func (*Executor) Init ¶

func (k *Executor) Init(driver bindings.ExecutorDriver)

func (*Executor) KillTask ¶

func (k *Executor) KillTask(driver bindings.ExecutorDriver, taskId *mesos.TaskID)

KillTask is called when the executor receives a request to kill a task.

func (*Executor) LaunchTask ¶

func (k *Executor) LaunchTask(driver bindings.ExecutorDriver, taskInfo *mesos.TaskInfo)

LaunchTask is called when the executor receives a request to launch a task. The happens when the k8sm scheduler has decided to schedule the pod (which corresponds to a Mesos Task) onto the node where this executor is running, but the binding is not recorded in the Kubernetes store yet. This function is invoked to tell the executor to record the binding in the Kubernetes store and start the pod via the Kubelet.

func (*Executor) Registered ¶

func (k *Executor) Registered(
	driver bindings.ExecutorDriver,
	executorInfo *mesos.ExecutorInfo,
	frameworkInfo *mesos.FrameworkInfo,
	slaveInfo *mesos.SlaveInfo,
)

Registered is called when the executor is successfully registered with the slave.

func (*Executor) Reregistered ¶

func (k *Executor) Reregistered(driver bindings.ExecutorDriver, slaveInfo *mesos.SlaveInfo)

Reregistered is called when the executor is successfully re-registered with the slave. This can happen when the slave fails over.

func (*Executor) Shutdown ¶

func (k *Executor) Shutdown(driver bindings.ExecutorDriver)

Shutdown is called when the executor receives a shutdown request.

type NodeInfo ¶

type NodeInfo struct {
	Cores int
	Mem   int64 // in bytes
}
