	// NetworkingV1 returns the networking/v1 Kubernetes client
	NetworkingV1() networkingv1.NetworkingV1Interface

	// RbacV1beta1 returns the rbac/v1beta1 Kubernetes client
	RbacV1beta1() rbacv1beta1.RbacV1beta1Interface

	// Dynamic returns the dynamic Kubernetes client
	Dynamic() dynamic.Interface

	// StewardV1alpha1 returns the steward.sap.com/v1alpha1 Kubernetes client

	// StewardInformerFactory returns the informer factory for Steward
	StewardInformerFactory() stewardinformer.SharedInformerFactory

	// TektonV1beta1 returns the tekton.dev/v1beta1 Kubernetes client
	TektonV1beta1() tektonclientv1beta1.TektonV1beta1Interface

	// TektonInformerFactory returns the informer factory for Tekton
	TektonInformerFactory() tektoninformers.SharedInformerFactory
}

ClientFactory is the interface for Kubernet client factories.

func NewClientFactory

func NewClientFactory(config *rest.Config, resyncPeriod time.Duration) ClientFactory

NewClientFactory creates new client factory based on rest config

type NamespaceManager

type NamespaceManager interface {
	Create(ctx context.Context, name string, annotations map[string]string) (string, error)
	Delete(ctx context.Context, name string) error
}

NamespaceManager manages namespaces

func NewNamespaceManager

func NewNamespaceManager(factory ClientFactory, prefix string, suffixLength uint8) NamespaceManager

NewNamespaceManager creates a new NamespaceManager.

type PipelineRun

type PipelineRun interface {
	fmt.Stringer
	GetAPIObject() *api.PipelineRun
	GetStatus() *api.PipelineStatus
	GetSpec() *api.PipelineSpec
	GetName() string
	GetKey() string
	GetRunNamespace() string
	GetAuxNamespace() string
	GetNamespace() string
	GetPipelineRepoServerURL() (string, error)
	HasDeletionTimestamp() bool
	AddFinalizer(ctx context.Context) error
	CommitStatus(ctx context.Context) ([]*api.StateItem, error)
	DeleteFinalizerIfExists(ctx context.Context) error
	InitState() error
	UpdateState(api.State, metav1.Time) error
	UpdateResult(api.Result, metav1.Time)
	UpdateContainer(*corev1.ContainerState)
	StoreErrorAsMessage(error, string) error
	UpdateRunNamespace(string)
	UpdateAuxNamespace(string)
	UpdateMessage(string)
}

PipelineRun is a wrapper for the K8s PipelineRun resource

func NewPipelineRun

func NewPipelineRun(ctx context.Context, apiObj *api.PipelineRun, factory ClientFactory) (PipelineRun, error)

NewPipelineRun creates a managed pipeline run object. If a factory is provided a new version of the pipelinerun is fetched. All changes are done on the fetched object. If no pipeline run can be found matching the apiObj, nil,nil is returned. An error is only returned if a Get for the pipelinerun returns an error other than a NotFound error. If you call with factory nil you can only use the Get* functions If you use functions changing the pipeline run without factroy set you will get an error. The provided PipelineRun object is never modified and copied as late as possible.

type PipelineRunByKeyFetcher

type PipelineRunByKeyFetcher interface {
	// ByKey fetches PipelineRun resource from Kubernetes
	// Return nil,nil if pipeline with key does not exist
	ByKey(ctx context.Context, key string) (*api.PipelineRun, error)
}

PipelineRunByKeyFetcher provides a function to fetch PipelineRuns by their key

type PipelineRunByNameFetcher

type PipelineRunByNameFetcher interface {
	// ByName fetches PipelineRun resource from Kubernetes by name and namespace
	// Return nil,nil if specified pipeline does not exist
	ByName(ctx context.Context, namespace, name string) (*api.PipelineRun, error)
}

PipelineRunByNameFetcher provides a function to fetch PipelineRuns by their name

type PipelineRunFetcher

type PipelineRunFetcher interface {
	PipelineRunByKeyFetcher
	PipelineRunByNameFetcher
}

PipelineRunFetcher combines PipelineRunByKeyFetcher and PipelineRunByNameFetcher

func NewClientBasedPipelineRunFetcher

func NewClientBasedPipelineRunFetcher(client stewardv1alpha1.StewardV1alpha1Interface) PipelineRunFetcher

NewClientBasedPipelineRunFetcher returns a PipelineRunFetcher that retrieves the objects from the given API client.

func NewListerBasedPipelineRunFetcher

func NewListerBasedPipelineRunFetcher(lister stewardLister.PipelineRunLister) PipelineRunFetcher

NewListerBasedPipelineRunFetcher returns a PipelineRunFetcher that retrieves the objects from the given `PipelineRunLister`. The returned fetcher provides the original pointers from the lister. Typically the lister is backed by a shared cache which must not be modified. Consumers should not mutate the original objects, but create deep copies when modification is required.

type RoleName

type RoleName string

RoleName to be attached

type ServiceAccountHelper

type ServiceAccountHelper interface {
	GetServiceAccountSecretNameRepeat(ctx context.Context) (string, error)
	GetServiceAccountSecretName(ctx context.Context) (string, error)
