The CloudEvents Plugin for Jenkins allows interoperability between different CI/CD tools by adopting industry-standard specification for events called CloudEvents.
By using this plugin in your workflows, you can emit and consume CloudEvents for various events in Jenkins relating to Jenkins objects (jobs, projects, queues, etc).
The standardization of events by adopting CloudEvents will make it easier to interoperate systems without having to write adapters.
There are 2 usages of this plugin:
-
Jenkins as a Source.
-
To configure Jenkins as a Source, first click on Manage Jenkins in the Root-Actions menu on the left.
-
Once you are in Manage Jenkins UI, search for Configure System under System Configuration.
-
Inside the Configure System UI, scroll down to the CloudEvents Plugin section and configure the following:
- Select the type of the sink.
- Enter the URL of the sink where requests from Jenkins will be routed.
- Select the events this sink will receive.
- Select the type of the sink.
-
-
Jenkins as a Sink.
- To use Jenkins as a Sink, enter the Jenkins Sink URL as the Sink to send CloudEvents from other systems.
- TODO: Jenkins Sink URL.
When users configure Jenkins to be used as a Source by providing the type of the Sink along with its URL, Jenkins will emit CloudEvents-compliant events which contains event-metadata and events-data. In this iteration of development, events will be sent over to the configured sink sequentially, that is, in the oder they happen.
CloudEvents emanating from Jenkins are sent over to the sink as an HTTP request. All events follow the CloudEvents binary content mode where the events metadata is present inside HTTP request-headers.
Below are the events this plugin supports, alongside event-metadata and event-data which will be emitted for each of these events.

TODO Decide where you're going to host your issues, the default is Jenkins JIRA, but you can also enable GitHub issues, If you use GitHub issues there's no need for this section; else add the following line:
Report issues and enhancements in the Jenkins issue tracker.
TODO review the default CONTRIBUTING file and make sure it is appropriate for your plugin, if not then add your own one adapted from the base file
