Question

A developer is troubleshooting an intermittent apply failure and wants to enable verbose Terraform logging, but also needs the log output written to a file for later analysis by a colleague rather than only appearing on the terminal. Which combination of environment variables should the developer set before running the command?

Accepted Answer

Set TF_LOG=DEBUG and TF_LOG_PATH=./terraform.log

Answer

Set TF_LOG=DEBUG and redirect using TF_OUTPUT=./terraform.log

Answer

Set TF_DEBUG=true and TF_LOG_FILE=./terraform.log

Answer

Set TF_LOG=TRACE only, since Terraform automatically writes to terraform.log in the working directory
