configuring-dapr-pubsub

Configure Dapr pub/sub by creating a component YAML file specifying your backend (Kafka or Redis), then apply it to your Kubernetes cluster with kubectl. Define metadata like connection strings and topic settings, then use Dapr CLI or APIs to publish and subscribe to events across your microservices.

Yes, Dapr pub/sub supports both Kafka and Redis as interchangeable backends. You configure the backend choice in your component metadata, allowing you to switch between them without changing your application code.

Use Dapr pub/sub subscriptions to define declarative routes and programmatic subscriptions that connect services. Deploy the configuration in Kubernetes, and services automatically discover and communicate through the pub/sub broker without direct dependencies.

Dapr pub/sub works with Kubernetes for production deployments and orchestration, but you can test locally using Dapr CLI before scaling. The Skill focuses on Kubernetes integration for reliable, distributed event-driven architectures.

Subscriptions map topics to service endpoints, enabling services to receive events automatically. Dapr supports declarative subscriptions in YAML and programmatic routes defined in code, routing published events to all registered subscribers.
