I am trying to deploy a binary utility along with my Python-based lambda to a Greengrass group.

Using a layer seemed like a natural way to accomplish this. No errors are encountered during the deployment, but I cannot find any evidence that the layer exists on the edge device (Ubuntu 18.04).

I have also been unable to find any documentation that confirms or denies layers work with Greengrass.

To move forward, I am bundling the utility within the Lambda deployment package itself. This seems workable, but a layer seems more flexible...

Any clarification would be appreciated.

Just from my experience, no, Layers do not get pushed to the Greengrass host, so if your lambda function depends on libraries in a layer, it will fail to run, even though deployments will go through without issue.

AWS I believe is no longer updating Greengrass V1, as they're focused on Greengrass V2. So I doubt this issue will get addressed. As a workaround, package everything within the lambda function and don't use layers for those functions getting pushed to Greengrass.
