第5章 Triggers

Triggers are an essential component in Knative Eventing that connect specific event sources to subscriber services based on defined filters. By creating a Trigger, you can dynamically manage how events are routed within your system, ensuring they reach the appropriate destination based on your business logic.

Brokers can be used in combination with triggers to deliver events from an event source to an event sink. Events are sent from an event source to a broker as an HTTP POST request. After events have entered the broker, they can be filtered by CloudEvent attributes using triggers, and sent as an HTTP POST request to an event sink.
