Adding new instance type


Is it possible to add new types of instances by modifying the template available at In particular, I would like to add r5 instances. I have tried to replicate all r4 entries in the template, but still get an error when trying to use them:

The instance configuration for this AWS Marketplace product is not supported. Please see the AWS Marketplace site for more information about supported instance types, regions, and operating systems. (Service: AmazonEC2; Status Code: 400; Error Code: UnsupportedOperation; Request ID: 13a03970-5b74-4996-a306-1c9e41640774)

Is it still possible to add a new instance type by modifying something else (as a user)?


Hello Victor,

Sadly those instances are not supported in the Alces Marketplace product.

The latest version of the Alces Flight Marketplace product is now available through OpenFlightHPC.

If you could have a go at using the OpenFlightHPC template ( instead of the Alces Marketplace one then you should be able to use r5 instances (after applying the changes you mentioned).

Hope this helps.

Kind Regards,
