Referencing ephemeral instance storage in block_devices mapping

[ginkel]

Is there a way to reference ephemeral instance storage for the block_devices mapping of an ec2_instance? Reading the source I'm under the impression that only EBS may be supported...

I'm running into the same issue. I tried specifying the virtual_name as ephemeral0, but still no luck. Terraform splits out the root_block_device, ebs_block_device, and ephemeral_block_device into separate attributes as noted here: https://www.terraform.io/docs/providers/aws/r/instance.html. I could see the implementation going either way. To keep backwards compatibility, we could add another field to the array entry for a block_device with a name like storage_type and values like ['ebs', 'instance'] with ebs being the default. Or split out the different storage types like terraform. I was thinking of working on this in the next few days. Any preference on the implementation?

@ginkel @benpillet, I believe this was addressed by #212. Can I close this issue?

[benpillet]

Yes. Looks like #212 covers it. Thanks!

Thanks, @benpillet!
