<Message type="note">
  It is not possible to use any other environment variable key that starts with `SCW_SLS`, regardless of case. Refer to the [Jobs limitations](/serverless-jobs/reference-content/jobs-limitations/#environment-variables-restrictions) documentation page for more information.

### Example

To display a variable, you can create a Job with the image `alpine:latest`, set the `startup_command` to `["/bin/sh", "-c"]`, and the `args` to `["echo $SCW_SLS_IMAGE"]`. This will display the image information with digest in the logs.
