This sample shows how to create an IBM Cloud Object Storage (COS) Event Source and hook it up to a Batch Job that will receive its events. An event is sent for each successful change to an object in the COS bucket.

The run script will create the job and an event subscription connecting the job to the specified COS bucket. The script will then upload a file to the bucket, resulting in the generation of an event. On receipt of the event, the a jobrun will be created based on the job. The job simply shows the CE_DATA environment variable which contains the information on the event on which the jobrun got triggered.

If you already have a COS instance that you want to use, you can set the COS_ID environment variable to the CRN of that instance. You can find existing instances by running

ibmcloud resource service-instances --service-name cloud-object-storage --long

If you want to use one of the listed instances, set COS_ID to the instance CRN/ID (the value in the first column of each row). If you leave this variable unset, the run script will attempt to create a lite (free of charge) COS instance for you, which it will then delete upon completion. It will not delete any existing instance you specify via the COS_ID variable.
