Enabling trace-level logs in Terraform Enterprise and Terraform CLI

To capture a trace log, set the environment variable TF_LOG to TRACE. Refer to the steps below for details in your Terraform product:

Terraform Enterprise

In Terraform Enterprise, perform these steps in your Workspace:

1. Navigate to Settings > General > User Interface, and select "Console UI"
2. Navigate to Variables > Workspace Variables, and add a new variable with "Environment" as category, TF_LOG as key, and TRACE as value
3. Start a new run
4. Click on "View raw log"

Once you are done debugging, you can simply delete the variable from the Terraform Enterprise UI.

Unix/Linux & macOS

In your Linux/macOS terminal, run the following commands:

1. Set the TF_LOG environment variable:
   

   export TF_LOG="TRACE"

2. Run the Terraform operation that you wish to debug, e.g., init, plan, apply, or import. Make sure you capture stdout and stderr with 2>&1, and disable ANSI color escape sequences with -no-color: 
   

   terraform plan -no-color 2>&1 | tee plan.log

Once you are done debugging, remove the variable by running: unset TF_LOG

Windows

In your PowerShell terminal, run the following commands:

1. Set the TF_LOG environment variable:
   

   $Env:TF_LOG="TRACE"

2. Run the Terraform operation that you wish to debug, e.g., init, plan, apply, or import. Make sure you capture stdout and stderr with 2>&1, and disable ANSI color escape sequences with -no-color: 
   

   terraform plan -no-color 2>&1 | Tee-Object -FilePath plan.log

Once you are done debugging, remove the variable by running: $Env:TF_LOG=""
