Functions

func DefaultItemBasedRateLimiter

func DefaultItemBasedRateLimiter() workqueue.RateLimiter

func Known() map[string]Constructor

Known returns a map of the registered controller Constructors

func Register

func Register(name string, fn Constructor)

Register registers a controller constructor with the controller package

Types

type ACMEOptions

type ACMEOptions struct {
	// ACMEHTTP01SolverImage is the image to use for solving ACME HTTP01
	// challenges
	HTTP01SolverImage string

	// HTTP01SolverResourceRequestCPU defines the ACME pod's resource request CPU size
	HTTP01SolverResourceRequestCPU resource.Quantity

	// HTTP01SolverResourceRequestMemory defines the ACME pod's resource request Memory size
	HTTP01SolverResourceRequestMemory resource.Quantity

	// HTTP01SolverResourceLimitsCPU defines the ACME pod's resource limits CPU size
	HTTP01SolverResourceLimitsCPU resource.Quantity

	// HTTP01SolverResourceLimitsMemory defines the ACME pod's resource limits Memory size
	HTTP01SolverResourceLimitsMemory resource.Quantity

	// DNS01CheckAuthoritative is a flag for controlling if auth nss are used
	// for checking propogation of an RR. This is the ideal scenario
	DNS01CheckAuthoritative bool

	// DNS01Nameservers is a list of nameservers to use when performing self-checks
	// for ACME DNS01 validations.
	DNS01Nameservers []string
}

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 CertificateOptions

type CertificateOptions struct {
	// EnableOwnerRef controls wheter wheter 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

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

type Context

type Context struct {
	// 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

	IssuerOptions
	ACMEOptions
	IngressShimOptions
	CertificateOptions
}

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
	DefaultIssuerKind                  string
	DefaultIssuerName                  string
	DefaultACMEIssuerChallengeType     string
	DefaultACMEIssuerDNS01ProviderName string
	DefaultAutoCertificateAnnotations  []string
}

type Interface

type Interface func(workers int, stopCh <-chan struct{}) error

Interface represents a controller that can run. '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.

type IssuerOptions

type IssuerOptions struct {
	// ClusterResourceNamespace is the namespace to store resources created by
	// non-namespaced resources (e.g. ClusterIssuer) in.
	ClusterResourceNamespace string

	// ClusterIssuerAmbientCredentials controls whether a cluster issuer should
	// 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(cert *x509.Certificate, crt *cmapi.Certificate) time.Duration

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

func (IssuerOptions) CanUseAmbientCredentials

func (o IssuerOptions) CanUseAmbientCredentials(iss cmapi.GenericIssuer) bool

func (IssuerOptions) CertificateNeedsRenew

func (o IssuerOptions) CertificateNeedsRenew(cert *x509.Certificate, crt *cmapi.Certificate) bool

func (IssuerOptions) ResourceNamespace

func (o IssuerOptions) ResourceNamespace(iss cmapi.GenericIssuer) string

type QueuingEventHandler

type QueuingEventHandler struct {
	Queue workqueue.RateLimitingInterface
}

QueuingEventHandler is an implementation of cache.ResourceEventHandler that simply queues objects that are added/updated/deleted.

func (*QueuingEventHandler) Enqueue

func (q *QueuingEventHandler) Enqueue(obj interface{})

func (*QueuingEventHandler) OnAdd

func (q *QueuingEventHandler) OnAdd(obj interface{})

func (*QueuingEventHandler) OnDelete

func (q *QueuingEventHandler) OnDelete(obj interface{})

func (*QueuingEventHandler) OnUpdate

func (q *QueuingEventHandler) OnUpdate(old, new interface{})
