Terraform: aws_spot_fleet_request: unexpected EOF (panic: interface conversion: interface is nil, not string)

[liquid-sky]

Terraform Version

Terraform v0.7.3

Affected Resource(s)

• aws_spot_fleet_request
  

  Terraform Configuration Files

Encrypted with Hashicorp GPG

Debug Output

Just before it dies it describes image to get the root and ephemeral block device configuration

This is the last segment that gets successfully executed.

Panic Output

Encrypted with Hashicorp GPG

Expected Behavior

When creating Spot Fleet, Terraform crashes after the fleet has been created and before it saves the state.

Terraform should launch Spot Fleet and save the state of configuration.

Actual Behavior

Terraform exits abruptly and abandons the state, however Spot Fleet gets created and TF quits while trying to describe configuration.

Steps to Reproduce

1. terraform apply

Unexpected EOF in spot fleet also causes other operations fail to save their states, such as creating autoscaling groups.

[moduspwnens]

In case it helps: Here's a ZIP containing a template that reproduces (what appears to be) the same issue. It's affecting me on Terraform 0.7.5 (but also occurred in 0.7.4).

If you comment out the second ebs_block_device in the launch_specification (/dev/xvdcz), it works.

Hi @stack72, are you able to help with this issue?

[paddycarver]

Hi! Thanks for reporting the bug, and really sorry for any issues it has caused you. I'm taking a look at this, so thanks for the detailed information. Really helpful.

I've reproduced the issue in terraform 0.7.8 and tip.

[paddycarver]

I've got a fix into master for this, but we _just_ missed the 0.7.9 release, so it'll be in the next release. If you have any questions or problems before that, please feel free to open an issue and we'll get it resolved. Thanks for reporting!

[liquid-sky]

Thanks a lot @paddyforan !
