[Terraform] tflint update causes builds using terraform feature to fail

[MathBouma]

The latest release of tflint (0.47.0) has broken terraform feature.

All devcontainers using terraform latest are failing as a result of a change in tflint.
The container script relies on a checksums.txt.sig file but this wasn't present in the latest release.
I have opened a ticket with tflint:
terraform-linters/tflint#1783

In case the issue needs to be resolved there, but if not a change will be required to this script to workaround this.

And they've closed the issues saying the checksums.txt.sig was deprecated and now removed, and there's a newer more correct way. Meaning it's now a problem for this project.

One workaround for the time being for me was to just pin to the version right before they removed the checksum:

devcontainer.json

  "features": {
    "ghcr.io/devcontainers/features/terraform:1": {
      "installSentinel": true,
      "installTFsec": true,
      "installTerraformDocs": true,
      "version": "latest",
      "tflint": "0.46.1", // Latest version of tflint caused issues, see: https://github.com/devcontainers/features/issues/581
      "terragrunt": "latest"
    }
  },

Thanks for raising! I've also run into this, found your closed issue on the tflint project, and eventually made my way back here 😄

Looking into a fix. Thanks Colter McQuay (@cjam) for sharing the workaround!

Version 1.3.1 of the terraform Feature is pinned to tflint 0.46.1 by default (can override with any version you'd like via the Feature's options). This should unblock folks that are using Feature defaults.

Keeping this issue open while a forward fix is worked on 👍

joshspicer should we close this issue as #586 is merged?
