Step 4 - Apply the Event Registration Subscription

Prerequisite step: Select your eventing backend

Prerequisite Option 1: Use NATS

NATS is the default eventing backend of SAP BTP, Kyma Runtime. If you haven't changed your eventing backend to SAP Event Mesh, then there are no additional steps required.

Prerequisite Option 2: Use SAP Event Mesh

Optionally, use Kyma Eventing with SAP Event Mesh (only if you're not using a free tier or free trial BTP account).

Note: By default, Kyma clusters have an Eventing backend based on NATS. However, it is possible to switch this backend to SAP Event Mesh if you're not using a free tier or free trial BTP account.

➡️ Setup SAP Event Mesh as your eventing backend for Kyma Runtime

Apply the Event Registration Subscription

  1. Create a Subscription to receive events. The subscription custom resource is used to subscribe to events.

    kubectl apply -f ./event-subscription/k8s/subscription.yaml

  2. Verify that the subscription has been created in the conference-registration namespace.

    kubectl get subscription -n conference-registration
