Terragrunt: validate-all broken since v0.16.0

[ldormoy]

v0.16.0 creates a .terragrunt-cache directory.

When I run terragrunt validate-all, I get:
10:51 $ terragrunt validate-all [terragrunt] [/home/me/git/project/staging/eu-west-1/networking] 2018/07/10 10:51:50 Running command: terraform --version [terragrunt] 2018/07/10 10:51:50 Error processing module at '/home/me/git/project/staging/eu-west-1/networking/.terragrunt-cache/K4mWZ7k7E85FwmjJeDdnsYYHZsQ/6PYnJZYoeYKyHmRAwweXnstOrvc/networking/terraform.tfvars'. How this module was found: Terragrunt config file found in a subdirectory of /home/me/git/project/staging/eu-west-1/networking. Underlying error: /home/me/git/project/staging/eu-west-1/networking/.terragrunt-cache/K4mWZ7k7E85FwmjJeDdnsYYHZsQ/6PYnJZYoeYKyHmRAwweXnstOrvc/networking/terraform.tfvars includes ../../../../terraform.tfvars, which itself includes ../../../../terraform.tfvars. Only one level of includes is allowed. [terragrunt] 2018/07/10 10:51:50 Unable to determine underlying exit code, so Terragrunt will exit with error code 1

Obviously the .terraform-cache subdirectory should be excluded.

Ah, that's my bad. We run plan-all and apply-all in tests, so I'm not sure how that was missed! I'll try to get a fix out today. Thanks for reporting.

Just pushed https://github.com/gruntwork-io/terragrunt/releases/tag/v0.16.1. New binaries should show up shortly. Let me know if that fixes the issue for you!

[ldormoy]

Nope, still happening (also with plan-all and I guess apply-all).

I suppose your tests don't catch it because you delete the workspace/container between each run, so they never use the cache directory?

The first lines of plan-all:

$ terragrunt -version
terragrunt version v0.16.1
$ terragrunt plan-all

Hm, that's perplexing. I'll look more into it tomorrow. Thx for the report.

[brikis98]

OK, let's try this one more time 😄

https://github.com/gruntwork-io/terragrunt/releases/tag/v0.16.2

Binaries should be there in a few minutes.

[ldormoy]

Looks good now!

Thanks for the quick fixes @brikis98
