Types ¶
type LaunchableTaskInfo ¶
type LaunchableTaskInfo struct { *task.TaskInfo // ConfigAddOn is the task config add on. ConfigAddOn *models.ConfigAddOn // Spec is the pod spec for the pod to be launched. Spec *pbpod.PodSpec }
LaunchableTaskInfo contains the info of a task to be launched.
type Lockable ¶
type Lockable interface { // LockKill locks kill operations including executor shutdown LockKill() // UnlockKill unlocks kill operations including executor shutdown UnlockKill() // LockLaunch locks launch operations LockLaunch() // UnlockLaunch unlocks launch operations UnlockLaunch() }
Lockable interface defines the operations that can be locked
type Manager ¶
type Manager interface { Lockable // Launch will launch tasks/pods using their config/spec on the specified // host using the acquired leaseID. Launch( ctx context.Context, leaseID string, hostname string, agentID string, tasks map[string]*LaunchableTaskInfo, rateLimiter *rate.Limiter, ) error // Kill will kill tasks/pods using their ID. Kill( ctx context.Context, id string, hostToReserve string, rateLimiter *rate.Limiter, ) error // ShutdownExecutor will shutdown the underlying mesos executor. This will // be a no-op for v1 LifecycleMgr. ShutdownExecutor( ctx context.Context, id string, agentID string, rateLimiter *rate.Limiter, ) error // TerminateLease will be called to terminate the acquired lease on // hostmgr in case of any errors. This will ensure that the hosts that // are leased are not freed up for placement in case we cannot place the // current set of tasks on them. TerminateLease( ctx context.Context, hostname string, agentID string, leaseID string, ) error // GetTasksOnDrainingHosts gets the taskIDs of the tasks on the // hosts in DRAINING state GetTasksOnDrainingHosts( ctx context.Context, limit uint32, timeout uint32, ) ([]string, error) }
Manager interface defines methods to kill workloads.
type Metrics ¶
type Metrics struct { Launch tally.Counter LaunchFail tally.Counter LaunchRetry tally.Counter LaunchDuration tally.Timer LaunchRateLimit tally.Counter Kill tally.Counter KillFail tally.Counter Shutdown tally.Counter ShutdownFail tally.Counter KillRateLimit tally.Counter TerminateLease tally.Counter TerminateLeaseFail tally.Counter GetTasksOnDrainingHosts tally.Counter GetTasksOnDrainingHostsFail tally.Counter }
Metrics is the struct containing all the counters that track internal state of lifecyclemgr.
func NewMetrics ¶
NewMetrics returns a new Metrics struct, with all metrics initialized and rooted at the given tally.Scope
