Event source
An event source is a component, service, or system that generates events for delivery to event consumers.
Platform Engineering on Kubernetes
An event source is a component that produces events and exposes them for delivery to event consumers.
- How it is used
- Uses event sources to collect platform activity for storage, transformation, aggregation, and delivery metrics.
- How deep it goes
- Explains source types, CloudEvents normalization, declarative configuration, routing, and persistence, but defers custom-source implementation details.
- Examples
- Demonstrates Knative API Server, GitHub, GitLab, Kafka, RabbitMQ, Tekton, Argo Events, and Kubernetes deployment-event sources.
- What you can do after
- Apply it via Knative Eventing by configuring a source, sending CloudEvents to a sink, and feeding downstream metric calculations.

Google Anthos in Action
An event source is a component that obtains events from an authoritative system and delivers them to Knative Eventing.
- How it is used
- Connects external or internal event-producing systems to Knative Eventing workflows.
- How deep it goes
- Explains source responsibility and pipeline placement, but defers detailed source implementation.
- Examples
- Uses a CloudPubSubSource configured with a topic and event-display Service sink.
- What you can do after
- Build a custom source or configure a predefined source to deliver events to a Broker.
