Functions

func CertsToSecret

func CertsToSecret(namespace string, certs *crypto.Certificates) []corev1.Secret

CertsToSecret creates secrets in the provided namespace, in compact form, from the provided certs.

func CreateOrUpdateSecrets

func CreateOrUpdateSecrets(ctx context.Context, client client.Client, secrets []corev1.Secret, update bool) ([]corev1.Secret, error)

CreateOrUpdateSecrets creates the provided secrets if they don't exist or updates them if they do.

func NewWatchAndReconcileSource

func NewWatchAndReconcileSource(cond <-chan struct{}, obj client.Object, eh handler.EventHandler) source.Source

Types

type Mutator

type Mutator interface {
	Mutate(obj client.Object) client.Object
}

Mutator is an interface to hold mutator functions for status updates.

type MutatorFunc

type MutatorFunc func(client.Object) client.Object

MutatorFunc is a function adaptor for Mutators.

func (MutatorFunc) Mutate

func (m MutatorFunc) Mutate(old client.Object) client.Object

Mutate adapts the MutatorFunc to fit through the Mutator interface.

type NamespaceGetter

type NamespaceGetter interface {
	GetNamespace() string
}

type ObjectKindNamespacedName

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

type Provider

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

Provider is the scaffolding for the Kubernetes provider. It sets up dependencies and defines the topology of the provider and its managed components, wiring them together.

func New

func New(cfg *rest.Config, svr *ec.Server, resources *message.ProviderResources) (*Provider, error)

New creates a new Provider from the provided EnvoyGateway.

func (*Provider) Start

func (p *Provider) Start(ctx context.Context) error

Start starts the Provider synchronously until a message is received from ctx.

type Update

type Update struct {
	NamespacedName types.NamespacedName
	Resource       client.Object
	Mutator        Mutator
}

Update contains an all the information needed to update an object's status. Send down a channel to the goroutine that actually writes the changes back.

type UpdateHandler

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

UpdateHandler holds the details required to actually write an Update back to the referenced object.

func NewUpdateHandler

func NewUpdateHandler(log logr.Logger, client client.Client) *UpdateHandler

func (*UpdateHandler) NeedLeaderElection

func (u *UpdateHandler) NeedLeaderElection() bool

func (*UpdateHandler) Start

func (u *UpdateHandler) Start(ctx context.Context) error

Start runs the goroutine to perform status writes.

func (*UpdateHandler) Writer

func (u *UpdateHandler) Writer() Updater

Writer retrieves the interface that should be used to write to the UpdateHandler.

type UpdateWriter

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

UpdateWriter takes status updates and sends these to the UpdateHandler via a channel.

func (*UpdateWriter) Send

func (u *UpdateWriter) Send(update Update)

Send sends the given Update off to the update channel for writing by the UpdateHandler.

type Updater

type Updater interface {
	Send(u Update)
}

Updater describes an interface to send status updates somewhere.
