Constants

const (
	// DefaultInterval is the default interval for retry operations.
	DefaultInterval = 5 * time.Second
	// DefaultSevereThreshold is the default threshold until an error reported by another component is treated as 'severe'.
	DefaultSevereThreshold = 30 * time.Second
	// DefaultTimeout is the default timeout and defines how long Gardener should wait
	// for a successful reconciliation of an Extension resource.
	DefaultTimeout = 3 * time.Minute
)

Variables

var TimeNow = time.Now

TimeNow returns the current time. Exposed for testing.

Types

type Extension

type Extension struct {
	extensionsv1alpha1.Extension
	// Timeout is the maximum waiting time for the Extension status to report readiness.
	Timeout time.Duration
	// Lifecycle defines when an extension resource should be updated during different operations.
	Lifecycle *gardencorev1beta1.ControllerResourceLifecycle
}

Extension contains information about the desired Extension resources as well as configuration information.

type Interface

type Interface interface {

	DeleteStaleResources(context.Context) error
	// WaitCleanupStaleResources waits until all unused Extension resources are cleaned up.
	WaitCleanupStaleResources(context.Context) error
	// Extensions returns the map of extensions where the key is the type and the value is an Extension structure.
	Extensions() map[string]Extension

	// WaitMigrateAfterKubeAPIServer waits until all Extension resources that should be handled after the kube-apiserver are migrated.
	WaitMigrateAfterKubeAPIServer(ctx context.Context) error
}

Interface contains references to an Extension deployer.

func New

func New(
	log logr.Logger,
	client client.Client,
	values *Values,
	waitInterval time.Duration,
	waitSevereThreshold time.Duration,
	waitTimeout time.Duration,
) Interface

New creates a new instance of Extension deployer.

type Values

type Values struct {
	// Namespace is the namespace into which the Extension resources should be deployed.
	Namespace string
	// Extensions is the map of extensions where the key is the type and the value is an Extension structure.
	Extensions map[string]Extension
}

Values contains the values used to create an Extension resources.
