Next steps

You can use the kn cli to list and manage available event sources or event source types for use with Knative Eventing.

Currently, kn supports management of the following event source types:

ApiServerSource: Connects a sink to the Kubernetes API server.
PingSource: Periodically sends ping events with a constant payload. It can be used as a timer.

Listing available event source types using `kn`

Procedure

List the available event source types in the terminal:

$ kn source list-types

Example output

TYPE              NAME                                            DESCRIPTION
ApiServerSource   apiserversources.sources.knative.dev            Watch and send Kubernetes API events to a sink
PingSource        pingsources.sources.knative.dev                 Periodically send ping events to a sink
SinkBinding       sinkbindings.sources.knative.dev                Binding for connecting a PodSpecable to a sink

You can also list available event source types in YAML format:
```
$ kn source list-types -o yaml
```

Listing available event sources using `kn`

List available event sources by entering the following command:

$ kn source list

Example output

NAME   TYPE              RESOURCE                               SINK         READY
a1     ApiServerSource   apiserversources.sources.knative.dev   svc:eshow2   True
b1     SinkBinding       sinkbindings.sources.knative.dev       svc:eshow3   False
p1     PingSource        pingsources.sources.knative.dev        svc:eshow1   True

Listing event sources of a specific type only

You can list event sources of a specific type only, by using the --type flag.

List available event sources of type PingSource by entering the following command:

$ kn source list --type PingSource

Example output

NAME   TYPE              RESOURCE                               SINK         READY
p1     PingSource        pingsources.sources.knative.dev        svc:eshow1   True
