Listing event sources and event source types

It is possible to view a list of all event sources or event source types that exist or are available for use on your OpenShift Container Platform cluster. You can use the Knative (kn) cli or the Developer perspective in the OpenShift Container Platform web console to list available event sources or event source types.

Listing available event source types by using the Knative cli

Using the Knative (kn) cli provides a streamlined and intuitive user interface to view available event source types on your cluster. You can list event source types that can be created and used on your cluster by using the kn source list-types cli command.

Prerequisites

  • The OpenShift Serverless Operator and Knative Eventing are installed on the cluster.

  • You have installed the Knative (kn) cli.

Procedure

  1. 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

  2. Optional: You can also list the available event source types in YAML format:

    $ kn source list-types -o yaml

Viewing available event source types within the Developer perspective

It is possible to view a list of all available event source types on your cluster. Using the OpenShift Container Platform web console provides a streamlined and intuitive user interface to view available event source types.

Prerequisites

  • You have logged in to the OpenShift Container Platform web console.

  • The OpenShift Serverless Operator and Knative Eventing are installed on your OpenShift Container Platform cluster.

  • You have created a project or have access to a project with the appropriate roles and permissions to create applications and other workloads in OpenShift Container Platform.

Procedure

  1. Access the Developer perspective.

  2. click +Add.

  3. click Event source.

  4. View the available event source types.

Listing available event sources by using the Knative cli

Using the Knative (kn) cli provides a streamlined and intuitive user interface to view existing event sources on your cluster. You can list existing event sources by using the kn source list command.

Prerequisites

  • The OpenShift Serverless Operator and Knative Eventing are installed on the cluster.

  • You have installed the Knative (kn) cli.

Procedure

  1. List the existing event sources in the terminal:

    $ kn source list
    Example output
    NAME   TYPE              RESOURCE                               SINK         READY
a1     ApiServerSource   apiserversources.sources.knative.dev   ksvc:eshow2   True
b1     SinkBinding       sinkbindings.sources.knative.dev       ksvc:eshow3   False
p1     PingSource        pingsources.sources.knative.dev        ksvc:eshow1   True

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

    $ kn source list --type <event_source_type>
    Example command
    $ kn source list --type PingSource
    Example output
    NAME   TYPE              RESOURCE                               SINK         READY
p1     PingSource        pingsources.sources.knative.dev        ksvc:eshow1   True
