explanation

type Controller ¶

type Controller struct {
	// The kubernetes client to use for processing decisions.
	client.Client
	// The controller will scope to objects using this operator name.
	// This allows multiple operators to coexist in the same cluster without
	// interfering with each other's decisions.
	OperatorName string
	// If the field indexing should be skipped (useful for testing).
	SkipIndexFields bool
}

The explanation controller populates two fields of the decision status.

First, it reconstructs the history of each decision. It will look for previous decisions for the same resource (based on ResourceID) and provide them through the decision history field.

Second, it will use the available context for a decision to generate a human-readable explanation of why the decision was made the way it was. This explanation is intended to help operators understand the reasoning behind scheduling decisions.

func (c *Controller) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error)

func (c *Controller) SetupWithManager(mgr manager.Manager) error

func (c *Controller) StartupCallback(ctx context.Context) error

type Explainer ¶

type Explainer struct {
	// The kubernetes client to use for fetching related data.
	client.Client
}

The explainer gets a scheduling decision and produces a human-readable explanation of why the decision was made the way it was.

func (e *Explainer) Explain(ctx context.Context, decision *v1alpha1.Decision) (string, error)
