)

Define types of agent for catalog

type Capabilities 

type Capabilities struct {
	Add  []string
	Drop []string
}

Capabilities is the capabilities a certain Container security context is capable of

type Collector 

type Collector interface {
	// Start starts a collector. The collector should run until the context
	// is done. It also gets a reference to the store that started it so it
	// can use Notify, or get access to other entities in the store.
	Start(context.Context, Component) error

	// Pull triggers an entity collection. To be used by collectors that
	// don't have streaming functionality, and called periodically by the
	// store.
	Pull(context.Context) error

	// GetID returns the identifier for the respective component.
	GetID() string

	// GetTargetCatalog gets the expected catalog.
	GetTargetCatalog() AgentType
}

Collector is responsible for collecting metadata about workloads.

type Component 

type Component interface {
	// Subscribe subscribes the caller to events representing changes to the
	// store, limited to events matching the filter.  The name is used for
	// telemetry and debugging.
	//
	// The first message on the channel is special: it contains an EventTypeSet
	// event for each entity currently in the store.  If the Subscribe call
	// occurs at agent startup, then the first message approximates entities
	// that were running before the agent started.  This is an inherently racy
	// distinction, but may be useful for decisions such as whether to begin
	// logging at the head or tail of an entity's logs.
	//
	// Multiple EventTypeSet messages may be sent, either as the entity's state
	// evolves or as information about the entity is reported from multiple
	// sources (such as a container runtime and an orchestrator).
	//
	// See the documentation for EventBundle regarding appropriate handling
	// for messages on this channel.
	Subscribe(name string, priority SubscriberPriority, filter *Filter) chan EventBundle

	GetKubernetesPod(id string) (*KubernetesPod, error)

	// GetKubernetesPodForContainer retrieves the ownership information for the
	// given container and returns the owner pod. This information might lag because
	// the kubelet check sets the `Owner` field but a container can also be stored by CRI
	// checks, which do not have ownership info. Thus, the function might return an error
	// when the pod actually exists.

	// the store. Also, when the entity exists, but with different values.
	// - EventTypeUnset: one for each entity that exists in the store but is not
	// present in newEntities.

Subscribers are expected to respond to EventBundles quickly. The Store will not move on to notify the next subscriber until the included channel Ch is closed. Subscribers which need to update their state before other subscribers are notified should close this channel once those updates are complete. Other subscribers should close the channel immediately. See the example for Store#Subscribe for details.

Only events for entities with one of the added kinds and matching the associated entity filter function will be delivered.

If no kind is added, events for entities of any kind will be delivered.

Similarly, only events for entities collected from the given source will be delivered, and the entities in the events will contain data only from that source. For example, if source is SourceRuntime, then only events from the runtime will be delivered, and they will not contain any additional metadata from orchestrators or cluster orchestrators. Use SourceAll to collect data from all sources. SourceAll is the default.

Only events of the given type will be delivered. Use EventTypeAll to collect data from all the event types. EventTypeAll is the default.
