Types

type ChangeProcessor

type ChangeProcessor interface {
	// CaptureUpsertChange captures an upsert change to a resource.
	// It panics if the resource is of unsupported type or if the passed Gateway is different from the one this
	// ChangeProcessor was created for.
	CaptureUpsertChange(obj client.Object)
	// CaptureDeleteChange captures a delete change to a resource.
	// The method panics if the resource is of unsupported type or if the passed Gateway is different from the one
	// this ChangeProcessor was created for.
	CaptureDeleteChange(resourceType ngftypes.ObjectType, nsname types.NamespacedName)
	// Process produces a graph-like representation of GatewayAPI resources.
	// If no changes were captured, the graph will be empty.
	Process() (graphCfg *graph.Graph)
	// GetLatestGraph returns the latest Graph.
	GetLatestGraph() *graph.Graph
}

ChangeProcessor processes the changes to resources and produces a graph-like representation of the Gateway configuration. It only supports one GatewayClass resource.

type ChangeProcessorConfig

type ChangeProcessorConfig struct {
	// Validators validate resources according to data-plane specific rules.
	Validators validation.Validators
	// EventRecorder records events for Kubernetes resources.
	EventRecorder record.EventRecorder
	// MustExtractGVK is a function that extracts schema.GroupVersionKind from a client.Object.
	MustExtractGVK kinds.MustExtractGVK
	// PlusSecrets is a list of secret files used for NGINX Plus reporting (JWT, client SSL, CA).
	PlusSecrets map[types.NamespacedName][]graph.PlusSecretFile
	// Logger is the logger for this Change Processor.
	Logger logr.Logger
	// GatewayCtlrName is the name of the Gateway controller.
	GatewayCtlrName string
	// GatewayClassName is the name of the GatewayClass resource.
	GatewayClassName string
}

ChangeProcessorConfig holds configuration parameters for ChangeProcessorImpl.

type ChangeProcessorImpl

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

ChangeProcessorImpl is an implementation of ChangeProcessor.

func NewChangeProcessorImpl

func NewChangeProcessorImpl(cfg ChangeProcessorConfig) *ChangeProcessorImpl

NewChangeProcessorImpl creates a new ChangeProcessorImpl for the Gateway resource with the configured namespace name.

func (*ChangeProcessorImpl) CaptureDeleteChange

func (c *ChangeProcessorImpl) CaptureDeleteChange(resourceType ngftypes.ObjectType, nsname types.NamespacedName)

func (*ChangeProcessorImpl) CaptureUpsertChange

func (c *ChangeProcessorImpl) CaptureUpsertChange(obj client.Object)

func (*ChangeProcessorImpl) GetLatestGraph

func (c *ChangeProcessorImpl) GetLatestGraph() *graph.Graph

type Updater

type Updater interface {
	Upsert(obj client.Object)
	Delete(objType ngftypes.ObjectType, nsname types.NamespacedName)
}

Updater updates the cluster state.
