Chapter 11. Subscribing functions to CloudEvents

Procedure

1. Subscribe the function to events for a given broker by running the following command:

   Example command

   Use the --source flag to specify the broker and one or more --filter flags to specify your filters.

   You can also omit the --source flag to use the default broker:
