}

Ensurer ensures that various standard Kubernets controlplane objects conform to the provider requirements. If they don't initially, they are mutated accordingly.

type EnsurerContext

type EnsurerContext interface {
	GetCluster(ctx context.Context) (*extensionscontroller.Cluster, error)
}

EnsurerContext wraps the actual context and cluster object.

func NewEnsurerContext

func NewEnsurerContext(client client.Client, object metav1.Object) EnsurerContext

NewEnsurerContext creates an ensurer context object.

func NewInternalEnsurerContext

func NewInternalEnsurerContext(cluster *extensionscontroller.Cluster) EnsurerContext

NewInternalEnsurerContext creates an ensurer context object.

type NoopEnsurer

type NoopEnsurer struct{}

NoopEnsurer provides no-op implementation of Ensurer. This can be anonymously composed by actual Ensurers for convenience.
