Functions

func LogEnqueueError 

func LogEnqueueError(logger *zap.SugaredLogger, f func(interface{}) error) func(interface{})

LogEnqueueError allows functions that assist with enqueing to return an error. Normal workflows work better when errors can be returned (instead of just logged). Therefore logError allows these functions to return an error and it will take care of swallowing and logging it.

func NewControllerLogger 

func NewControllerLogger(ctx context.Context, resource string) *zap.SugaredLogger

Types

type Base 

type Base struct {
	// KubeClientSet allows us to talk to the k8s for core APIs
	KubeClientSet kubernetes.Interface

	// KfClientSet allows us to configure Kf objects
	KfClientSet kfclientset.Interface

	// ConfigMapWatcher allows us to watch for ConfigMap changes.
	ConfigMapWatcher configmap.Watcher

	// NamespaceLister allows us to list Namespaces. We use this to check for
	// terminating namespaces.
	NamespaceLister v1listers.NamespaceLister

	// SecretLister allows us to list Secrets.
	SecretLister v1listers.SecretLister

	// SecretInformer allows us to AddEventHandlers for Secrets.
	SecretInformer informerscorev1.SecretInformer
}

Base implements the core controller logic, given a Reconciler.

func NewBase 

func NewBase(ctx context.Context, cmw configmap.Watcher) *Base

NewBase instantiates a new instance of Base implementing the common & boilerplate code between our reconcilers.

func (*Base) CleanupCompletedTaskRunSidecars 

func (b *Base) CleanupCompletedTaskRunSidecars(ctx context.Context, tr *tektonv1beta1.TaskRun) error

CleanupCompletedTaskRunSidecars removes sidecars if the TaskRun is completed.

func (*Base) IsNamespaceTerminating 

func (base *Base) IsNamespaceTerminating(namespace string) bool

IsNamespaceTerminating returns true if the namespace is marked as terminating and false if the state is unknown or not terminating.

func (*Base) ReconcileDeployment 

func (b *Base) ReconcileDeployment(ctx context.Context, desired, actual *appsv1.Deployment) (*appsv1.Deployment, error)

ReconcileDeployment syncs the existing K8s Deployment to the desired Deployment.

func (*Base) ReconcileRole 

func (b *Base) ReconcileRole(
	ctx context.Context,
	desired *rbacv1.Role,
	actual *rbacv1.Role,
) (*rbacv1.Role, error)

ReconcileRole syncs the existing K8s Role to the desired Role.

func (*Base) ReconcileRoleBinding 

func (b *Base) ReconcileRoleBinding(
	ctx context.Context,
	desired *rbacv1.RoleBinding,
	actual *rbacv1.RoleBinding,
) (*rbacv1.RoleBinding, error)

ReconcileRoleBinding syncs the existing K8s RoleBinding to the desired RoleBinding.

func (*Base) ReconcileSecret 

func (b *Base) ReconcileSecret(
	ctx context.Context,
	desired *corev1.Secret,
	actual *corev1.Secret,
) (*corev1.Secret, error)

ReconcileSecret syncs the existing K8s Secret to the desired Secret.

func (*Base) ReconcileService 

func (b *Base) ReconcileService(ctx context.Context, desired, actual *corev1.Service) (*corev1.Service, error)

ReconcileService syncs the existing K8s Service to the desired Service.

func (*Base) ReconcileServiceAccount 

func (b *Base) ReconcileServiceAccount(
	ctx context.Context,
	desired *corev1.ServiceAccount,
	actual *corev1.ServiceAccount,
	checkForWI bool,
) (*corev1.ServiceAccount, error)

ReconcileServiceAccount syncs the actual service account to the desired SA. The reconciliation merges the secrets on the service accounts rather than replacing them. This is because the k8s cluster creates a default token secret per SA after the SA is first created.
