Types

type CapsulePipeline 

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

func NewCapsulePipeline 

func NewCapsulePipeline(
	config *configv1alpha1.OperatorConfig,
	scheme *runtime.Scheme,
	logger logr.Logger,
) *CapsulePipeline

func (*CapsulePipeline) AddStep 

func (p *CapsulePipeline) AddStep(step Step[CapsuleRequest])

func (*CapsulePipeline) DeleteCapsule 

func (p *CapsulePipeline) DeleteCapsule(
	ctx context.Context,
	capsule *v1alpha2.Capsule,
	client client.Client,
	opts ...CapsuleRequestOption,
) (*Result, error)

func (*CapsulePipeline) RunCapsule 

func (p *CapsulePipeline) RunCapsule(
	ctx context.Context,
	capsule *v1alpha2.Capsule,
	client client.Client,
	opts ...CapsuleRequestOption,
) (*Result, error)

func (*CapsulePipeline) Steps 

func (p *CapsulePipeline) Steps() []Step[CapsuleRequest]

type CapsuleRequest 

type CapsuleRequest interface {
	Request
	// Capsule returns a deepcopy of the capsule object being reconciled.
	Capsule() *v1alpha2.Capsule
	// MarkUsedObject marks the object as used by the Capsule which will be present in the Capsule's Status
	MarkUsedObject(res v1alpha2.UsedResource) error
}

CapsuleRequest contains a single reconcile request for a given capsule. It contains both the set of existing kubernetes objects owned by the capsule and the set of objects recorded to be applied after all steps in the pipeline has been executed (called 'new' objects). The set of existing objects cannot be modified (as the interface does not allow for writing to Kubernetes) but there are both read and write access to the set of new objects.

	// Delete records the given object to be deleted.
	// The behaviour is such that that calling req.Delete(obj) and then req.GetNew(obj)
	// returns a not-found error from GetNew.
	// If an object of the given type and name is present in the cluster, calling req.GetExisting(obj) succeds
	// as calls to Delete (or Set) will only be applied to the cluster at the very end of the reconcilliation.
