Functions

func Accept 

func Accept(ops ...AcceptOpt) *scheduler.Call

Accept returns an accept call with the given parameters. Callers are expected to fill in the FrameworkID and Filters.

func AcceptInverseOffers 

func AcceptInverseOffers(offerIDs ...mesos.OfferID) *scheduler.Call

AcceptInverseOffers returns an accept-inverse-offers call for the given offer IDs. Callers are expected to fill in the FrameworkID and Filters.

func Acknowledge 

func Acknowledge(agentID, taskID string, uuid []byte) *scheduler.Call

Acknowledge returns an acknowledge call with the given parameters. Callers are expected to fill in the FrameworkID.

func AcknowledgeOperationStatus added in v0.0.7 

func AcknowledgeOperationStatus(agentID, resourceProviderID string, uuid []byte, operationID string) *scheduler.Call

AcknowledgeOperationStatus acks the receipt of an operation status update. Schedulers are responsible for explicitly acknowledging the receipt of updates which have the 'OperationStatusUpdate.status().uuid()' field set. Such status updates are retried by the agent or resource provider until they are acknowledged by the scheduler. agentID and resourceProviderID are optional, the remaining fields are required.

func CallNoData 

func CallNoData(ctx context.Context, caller Caller, call *scheduler.Call) error

CallNoData is a convenience func that executes the given Call using the provided Caller and always drops the response data.

func Decline 

func Decline(offerIDs ...mesos.OfferID) *scheduler.Call

Decline returns a decline call with the given parameters. Callers are expected to fill in the FrameworkID and Filters.

func DeclineInverseOffers 

func DeclineInverseOffers(offerIDs ...mesos.OfferID) *scheduler.Call

DeclineInverseOffers returns a decline-inverse-offers call for the given offer IDs. Callers are expected to fill in the FrameworkID and Filters.

func Filters 

func Filters(fo ...mesos.FilterOpt) scheduler.CallOpt

Filters sets a scheduler.Call's internal Filters, required for Accept and Decline calls.

func Framework 

func Framework(id string) scheduler.CallOpt

Framework sets a scheduler.Call's FrameworkID

func Kill 

func Kill(taskID, agentID string) *scheduler.Call

Kill returns a kill call with the given parameters. Callers are expected to fill in the FrameworkID.

func Message 

func Message(agentID, executorID string, data []byte) *scheduler.Call

Message returns a message call with the given parameters. Callers are expected to fill in the FrameworkID.

OpLaunch returns a launch operation builder for the given tasks

func OpLaunchGroup 

func OpLaunchGroup(ei mesos.ExecutorInfo, ti ...mesos.TaskInfo) mesos.Offer_Operation

func OpReserve 

func OpReserve(rs ...mesos.Resource) mesos.Offer_Operation

func OpShrinkVolume added in v0.0.8 

func OpShrinkVolume(v mesos.Resource, s mesos.Value_Scalar) mesos.Offer_Operation

func OpUnreserve 

func OpUnreserve(rs ...mesos.Resource) mesos.Offer_Operation

func Reconcile 

func Reconcile(opts ...scheduler.ReconcileOpt) *scheduler.Call

Reconcile returns a reconcile call with the given parameters. See ReconcileTask. Callers are expected to fill in the FrameworkID.

func ReconcileOperations added in v0.0.7 

func ReconcileOperations(req []ReconcileOperationRequest) *scheduler.Call

ReconcileOperations allows the scheduler to query the status of operations. This causes the master to send back the latest status for each operation in 'req', if possible. If 'req' is empty, then the master will send the latest status for each operation currently known.

func ReconcileTasks 

func ReconcileTasks(tasks map[string]string) scheduler.ReconcileOpt

ReconcileTasks constructs a []Call_Reconcile_Task from the given mappings: 

map[string]string{taskID:agentID}

Map keys (taskID's) are required to be non-empty, but values (agentID's) *may* be empty.

func RefuseSeconds added in v0.0.4 

func RefuseSeconds(d time.Duration) scheduler.CallOpt

RefuseSeconds returns a calls.Filters option that sets RefuseSeconds to the given duration

func RefuseSecondsWithJitter 

func RefuseSecondsWithJitter(r *rand.Rand, d time.Duration) scheduler.CallOpt

RefuseSecondsWithJitter returns a calls.Filters option that sets RefuseSeconds to a random number of seconds between 0 and the given duration.

func Request 

func Request(requests ...mesos.Request) *scheduler.Call

Request returns a resource request call with the given parameters. Callers are expected to fill in the FrameworkID.

func Revive 

func Revive() *scheduler.Call

Revive returns a revive call. Callers are expected to fill in the FrameworkID.

func ReviveWith added in v0.0.5 

func ReviveWith(roles []string) *scheduler.Call

Revive returns a revive call with the given filters. Callers are expected to fill in the FrameworkID.

func Shutdown 

func Shutdown(executorID, agentID string) *scheduler.Call

Shutdown returns a shutdown call with the given parameters. Callers are expected to fill in the FrameworkID.

func Subscribe 

func Subscribe(info *mesos.FrameworkInfo) *scheduler.Call

Subscribe returns a subscribe call with the given parameters. The call's FrameworkID is automatically filled in from the info specification.

func SubscribeTo 

func SubscribeTo(frameworkID string) scheduler.CallOpt

SubscribeTo returns an option that configures a SUBSCRIBE call w/ a framework ID. If frameworkID is "" then the SUBSCRIBE call is cleared of all framework ID references. Panics if the call does not contain a non-nil Subscribe reference.

Types

type AcceptOpt

type AckError added in v0.0.4 

type AckError struct {
	Ack   *scheduler.Call // Ack is REQUIRED
	Cause error           // Cause is REQUIRED
}

AckError wraps a caller-generated error and tracks the call that failed. It may be reported for either a task status ACK error, or an offer operation status ACK error.

func (*AckError) Error added in v0.0.4 

func (err *AckError) Error() string

type Caller 

type Caller interface {
	// Call issues a call to Mesos and properly manages call-specific HTTP response headers & data.
	Call(context.Context, *scheduler.Call) (mesos.Response, error)
}

Caller is the public interface this framework scheduler's should consume

type CallerFunc 

type CallerFunc func(context.Context, *scheduler.Call) (mesos.Response, error)

CallerFunc is the functional adaptation of the Caller interface

func (CallerFunc) Call 

func (f CallerFunc) Call(ctx context.Context, c *scheduler.Call) (mesos.Response, error)

Call implements the Caller interface for CallerFunc

type OfferOperations 

type OfferOperations []mesos.Offer_Operation

func (OfferOperations) WithOffers 

func (ob OfferOperations) WithOffers(ids ...mesos.OfferID) AcceptOpt

WithOffers allows a client to pair some set of OfferOperations with multiple resource offers. Example: calls.Accept(calls.OfferOperations{calls.OpLaunch(tasks...)}.WithOffers(offers...))

type ReconcileOperationRequest added in v0.0.7 

type ReconcileOperationRequest struct {
	OperationID        string // OperationID is required
	AgentID            string // AgentID is optional
	ResourceProviderID string // ResourceProviderID is optional
}

ReconcileOperationRequest is a convenience type for which each instance maps to an instance of scheduler.Call_ReconcileOfferOperations_Operation.
