    The following command installs the Eventing Sugar Controller:

    Automatic Broker Creation

    One way to create a Broker is to manually apply a resource to a cluster using the default settings:

    1. Copy the following YAML into a file:

      2. metadata:
      3.   name: default
      4.   namespace: default

    2. Apply the YAML file by running the command:

    There might be cases where automated Broker creation is desirable, such as on namespace creation, or on Trigger creation. The Sugar controller enables those use-cases:

    • When a Namespace is labeled with eventing.knative.dev/injection=enabled, the sugar controller will create a default Broker named “default” in that namespace.
    • When a Trigger is annotated with eventing.knative.dev/injection=enabled, the controller will create a Broker named by that Trigger in the Trigger’s Namespace.

    When a Broker is deleted and the mentioned labels or annotations are in use, the Sugar Controller will automatically recreate a default Broker.

    Creating a “default” Broker when creating a Namespace:

    To automatically create a Broker after a namespace exists, label the Namespace:

    If the Broker named “default” already exists in the Namespace, the Sugar Controller will do nothing.

    Trigger Example

    Create a “default” Broker in the Trigger’s Namespace when creating a Trigger:

    If the Broker named “default” already exists in the Namespace, the Sugar Controller will do nothing and the Trigger will not own the existing Broker.
