Overview ¶
Package scheduler is the placement port (ADR-0017): the control-plane decision of which worker/node runs a function replica. V1 ships a single-node driver (internal/scheduler/singlenode); multi-node bin-packing across registered worker nodes is a driver swap behind this port. The controller's Function reconciler is the caller — this package imports no controller, store, or runtime; placement is decided from the Request alone.

Variables ¶
var ErrNoMatchingPlatform = errors.New("no worker node matches the artifact's platforms")
ErrNoMatchingPlatform is wrapped (fault.Invalid) by Schedule when no worker node's platform is in Request.Platforms (ADR-0145).
Functions ¶
This section is empty.
Types ¶
type Placement ¶
type Placement struct {
WorkerNode v1.ObjectName
}
Placement is the scheduler's decision: which worker/node runs the replica.
type Request ¶
type Request struct {
Namespace v1.NamespaceName
Name v1.ObjectName
Replica int
// Platforms the artifact provides (ADR-0145); empty means any.
Platforms []v1.OCIPlatform
}
Request identifies a function replica to place. A multi-node driver will extend this with resource fields (from the Function `resources` spec) when it first bin-packs on them; V1 carries no inert fields.

Package schedulercontract is the shared conformance suite for the scheduler.Scheduler port (ADR-0017, ADR-0145): Run asserts the port guarantee against any driver — a valid request yields a non-empty Placement.WorkerNode and no error, unless it lists artifact platforms none of which the driver's node runs.

Package singlenode is the single-node scheduler driver (ADR-0017): it places every function replica on one configured local worker — deterministic, and total except for an artifact built for other platforms than the node's (ADR-0145).
