type BlockingEventHandler

type BlockingEventHandler struct {
	WorkFunc func(obj interface{})

BlockingEventHandler is an implementation of cache.ResourceEventHandler that simply synchronously calls it's WorkFunc upon calls to OnAdd, OnUpdate or OnDelete.

func (*BlockingEventHandler) Enqueue

func (b *BlockingEventHandler) Enqueue(obj interface{})

func (*BlockingEventHandler) OnAdd

func (b *BlockingEventHandler) OnAdd(obj interface{})

func (*BlockingEventHandler) OnDelete

func (b *BlockingEventHandler) OnDelete(obj interface{})

func (*BlockingEventHandler) OnUpdate

func (b *BlockingEventHandler) OnUpdate(old, new interface{})

type Builder

type Builder struct {
	// contains filtered or unexported fields

Builder is used to build controllers that implement the queuingController interface

func NewBuilder

func NewBuilder(controllerctx *Context, name string) *Builder

New creates a basic Builder, setting the sync call to the one given

func (*Builder) Complete

func (b *Builder) Complete() (Interface, error)

func (*Builder) First

func (b *Builder) First(function func(context.Context)) *Builder

First will register a function that will be called once, after the controller has been initialised. They are queued, run sequentially, and block "With" runDurationFuncs from running until all are complete.

func (*Builder) For

func (b *Builder) For(ctrl queueingController) *Builder

func (*Builder) With

func (b *Builder) With(function func(context.Context), duration time.Duration) *Builder

With will register an additional function that should be called every 'duration' alongside the controller. This is useful if a controller needs to periodically run a scheduled task.

type CertificateOptions

type CertificateOptions struct {
	// EnableOwnerRef controls whether the certificate is configured as an owner of
	// secret where the effective TLS certificate is stored.
	EnableOwnerRef bool

type Constructor

type Constructor func(ctx *Context) (Interface, error)

Constructor is a function that creates a new control loop given a controller Context.

type Context

type Context struct {
	// RootContext is the root context for the controller
	RootContext context.Context

	// StopCh is a channel that will be closed when the controller is signalled
	// to exit
	StopCh <-chan struct{}
	// RESTConfig is the loaded Kubernetes apiserver rest client configuration
	RESTConfig *rest.Config
	// Client is a Kubernetes clientset
	Client kubernetes.Interface
	// CMClient is a cert-manager clientset
	CMClient clientset.Interface
	// Recorder to record events to
	Recorder record.EventRecorder

	// KubeSharedInformerFactory can be used to obtain shared
	// SharedIndexInformer instances for Kubernetes types
	KubeSharedInformerFactory kubeinformers.SharedInformerFactory
	// SharedInformerFactory can be used to obtain shared SharedIndexInformer
	// instances
	SharedInformerFactory informers.SharedInformerFactory

	// Namespace is the namespace to operate within.
	// If unset, operates on all namespaces
	Namespace string

	// Clock should be used to access the current time instead of relying on
	// time.Now, to make it easier to test controllers that utilise time
	Clock clock.Clock

	// Metrics is used for exposing Prometheus metrics across the controllers
	Metrics *metrics.Metrics


Context contains various types that are used by controller implementations. We purposely don't have specific informers/listers here, and instead keep a reference to a SharedInformerFactory so that controllers can choose themselves which listers are required.

type IngressShimOptions

type IngressShimOptions struct {
	// Default issuer/certificates details consumed by ingress-shim
	DefaultIssuerName                 string
	DefaultIssuerKind                 string
	DefaultIssuerGroup                string
	DefaultAutoCertificateAnnotations []string

type Interface

type Interface interface {
	// Run will start a controller. 'workers' should be the  number of
	// independent goroutines for this controller in question that are to be
	// run, and the workers should shut down upon a signal on stopCh.
	// This method should block until all workers have exited cleanly, thus
	// allowing for graceful shutdown of control loops.
	Run(workers int, stopCh <-chan struct{}) error

Interface represents a controller that can be run.

func NewController

func NewController(
	ctx context.Context,
	name string,
	metrics *metrics.Metrics,

	// pick up ambient credentials, such as those from metadata services, to
	// construct clients.
	ClusterIssuerAmbientCredentials bool

	// IssuerAmbientCredentials controls whether an issuer should pick up ambient
	// credentials, such as those from metadata services, to construct clients.
	IssuerAmbientCredentials bool

	// RenewBeforeExpiryDuration is the default 'renew before expiry' time for Certificates.
	// Once a certificate is within this duration until expiry, a new Certificate
	// will be attempted to be issued.
	RenewBeforeExpiryDuration time.Duration

func (IssuerOptions) CalculateDurationUntilRenew

func (o IssuerOptions) CalculateDurationUntilRenew(ctx context.Context, cert *x509.Certificate, crt *cmapi.Certificate) time.Duration

CalculateDurationUntilRenew calculates how long cert-manager should wait to until attempting to renew this certificate resource.
