EBS Optimised Instances #12

Closed ErnstTmp closed 7 years ago

ErnstTmp commented 7 years ago

Hello, if I run the code (which is great) with an master instance that is not EBS Optimised (m3.large) by default, I get the error message from boto: botocore.exceptions.ClientError: An error occurred (Unsupported) when calling the RunInstances operation: EBS-optimized instances are not supported for your requested configuration. Please check the documentation for supported configurations.

With m4.large, which is EBS optimised by default, it works (if I use a non-EBSOptimised routine for the workers, the Spot Instance Request shows an error in the AWS Console, and the instances do not start. This is painfull, because m4.large are much more expensive.

Thanks, Ernst

The solution is to set EbsOptimized to False in scripts/launch.py.
