Types

type Config

type Config struct {
	// Namespaces specifies the namespaces where Resources[] exist.
	// +required
	Namespaces []string `json:"namespaces"`

	// AllNamespaces indicates whether this source is watching all
	// existing namespaces
	AllNamespaces bool `json:"allNamespaces"`

	// Resource is the resource this source will track and send related
	// lifecycle events from the Kubernetes ApiServer.
	// +required
	Resources []ResourceWatch `json:"resources"`

	// ResourceOwner is an additional filter to only track resources that are
	// owned by a specific resource type. If ResourceOwner matches Resources[n]
	// then Resources[n] is allowed to pass the ResourceOwner filter.
	// +optional
	ResourceOwner *v1.APIVersionKind `json:"owner,omitempty"`

	// EventMode controls the format of the event.
	// `Reference` sends a dataref event type for the resource under watch.
	// `Resource` send the full resource lifecycle event.
	// Defaults to `Reference`
	// +optional
	EventMode string `json:"mode,omitempty"`

	// Filters is an experimental field that conforms to the CNCF CloudEvents Subscriptions
	// API. It's an array of filter expressions that evaluate to true or false.
	// If any filter expression in the array evaluates to false, the event MUST
	// NOT be sent to the Sink. If all the filter expressions in the array
	// evaluate to true, the event MUST be attempted to be delivered. Absence of
	// a filter or empty array implies a value of true.
	//
	// +optional
	Filters []eventingv1.SubscriptionsAPIFilter `json:"filters,omitempty"`
}

type Key

type Key struct{}

Key is used as the key for associating information with a context.Context.

type ResourceWatch

type ResourceWatch struct {
	// GVR the group version resource of the resource to watch.
	GVR schema.GroupVersionResource `json:"gvr"`

	// LabelSelector filters this source to objects to those resources pass the
	// label selector.
	// +optional
	LabelSelector string `json:"selector,omitempty"`
