# knative event

[knative events](https://knative.dev/docs/eventing/) provide composable primitives to enable late-binding event sources and event consumers.

This example is based on the python [helloworld](https://knative.dev/docs/eventing/samples/helloworld/helloworld-python/).

A more typed approach would be to extend https://github.com/cloudevents/sdk-rust which is work under progress.

In this directory run the following command:

```
$ roche build
$ docker run -p 8080:8080 YOUR_REGISTRY_ID/dev-event
$ curl -s -d {} http://localhost:8080/
{"msg":"Hi from rust app!"}
```

To see the response headers use the -v flag.
```
$ curl -s -v -d {} http://localhost:8080/
