Before you submit job in the next step and handle at the device using code, you need to create the job configuration file and dependency file.

You want to create a simple job for the workshop. The job will have location of a configuration file stored in S3 bucket. As part of the job processing, the device will download the configuration file.

1. The job configuration file is in json format and have no fixed schema. Create a file dojojob.json and copy-paste the following configuration text.

   {
       "version" : "1.0",
       "configfile": "${aws:iot:s3-presigned-url:https://s3.eu-west-1.amazonaws.com/dojo-job/dojoconfig.txt}"
   }
   

   `

2. The configuration provides location to a file dojoconfig.txt in dojo-job bucket in the Ireland region. If you created bucket with a different name then replace dojo-job with that one. The device will use job configuration to download this file from the S3 bucket. When the job is submitted, AWS IoT Device Management will include a presigned-url for the S3 based file in order to facilitate the download.

3. Next, you create the dojoconfig.txt file which will have some dummy data for this workshop. Create a file dojoconfig.txt and copy-paste the following text.

   Dummy Configuration for the workshop.
   

   `

4. Finally, upload the dojojob.json and dojoconfig.txt files to the dojo-job bucket. If you created bucket with a different name, then upload there.

   

5. The job files are ready. It is time to submit job from the AWS IoT Device Management and see how the device processes it.
