I'm trying to expose the webhook externally, however it doesn't seem to work for me.

apiVersion: v1 kind: Service metadata: name: webhook-eventsource namespace: argo-events spec: ports: - name: tcp port: 12000 protocol: TCP targetPort: 12000 selector: eventsource-name: webhook type: NodePort

Do you have any examples of how to implement it with ingress?

@Pzharyuk If you're exposing it through ingress, you just have to add Ingress resource that points to the Service.
