Enabling trace-level logs in Terraform CLI, Cloud or Enterprise

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

Terraform Cloud/Enterprise

If using Terraform Cloud or Terraform Enterprise with Remote Execution, perform these steps in your Workspace:

• Navigate to Settings > General, and set the User Interface setting to "Console UI"
• Navigate to Variables > Workspace Variables, and add an "Environment variable" with TF_LOG as key and TRACE as value
• Start a new run
• (Optional) Download the streamed log for further examination in your preferred code editor. You can find the download button towards the top of the failed run.

TIP: Changing the extension of the log file from.txt to .log will enable colored syntax highlighting for most code editors — which can make it easier to read.

Unix/Linux & macOS Operating Systems

In your Linux/macOS terminal type this, making sure you capture both stderr and stdout:

export TF_LOG=TRACE
terraform apply -no-color 2>&1 | tee apply.log

Windows Operating Systems

In your PowerShell terminal, use this example:

$Env:TF_LOG = "TRACE"
terraform apply -no-color 2>&1 | Tee-Object -FilePath apply.log

Once the issue is resolved, unset the TF_LOG environment variable to disable the enhanced logging.
