OS Information

• OS: Linux
• coder --version: Coder v0.5.5-devel+2d3dc43 Tue May 10 07:44:09 UTC 2022

Steps to Reproduce

1. Set a terraform environment variable: export TF_LOG=1
2. Run coder server
3. Create first template: coder templates create docker-local -d ~/src/cdr/coder/examples/docker-local

There should be no issue creating the template, or detailed hints on how to fix the problem (e.g. coder server is running with these environment variables set, please restart it without).

Actual

Template creation fails:

Notes

Considering this comment I wanted to see if I can get more information out of terraform (a naive approach). I think it's fine the value can't be changed but I would have expected this value to either propagate to terraform or for the server to either inform of a way to fix it or filter out the variable.

We could for instance filter out some incompatible TF_ env vars here, potentially logging the exclusion as a warning:

AC

Replace the terraform exec command with directly executing terraform
Test for the steps to repro this bug to validate this case is covered
Expose in the logs that the env vars are set
