Are you looking for an efficient way to profile your Terraform runs? Look no further! The tf-profile tool, built in Go, provides a modern command line experience to analyze your Terraform executions. In this guide, we’ll walk you through the installation and basic usage of tf-profile, and offer some troubleshooting tips to make your journey smoother.

Installation Steps

Setting up tf-profile is straightforward. Here’s how you can get started:

1. Brew Install (macOS)

If you are using macOS, you can install tf-profile via Homebrew:

• brew tap datarootsio/tf-profile
• brew install tf-profile

2. Binary Download

If you prefer not to use Homebrew, simply download the binary:

• Head over to the releases page.
• Choose the binary that matches your operating system.
• Copy it into a directory included in your $PATH, typically /usr/local/bin on Linux systems.

3. Using Docker

If you want to avoid installation, you can run tf-profile using Docker:

cat my_log_file.log | docker run -i qbruynseraedetf-profile:0.2.0 stats

Optionally, set up an alias for convenience:

alias tf-profile='docker run -i qbruynseraedetf-profile:0.2.0 cat my_log_file.log | tf-profile'

4. Build from Source

If you’d like to build tf-profile from source, ensure you have at least Go version 1.20 installed:

git clone git@github.com:QuintenBruynseraede/tf-profile.git
cd tf-profile
go build .
sudo ln -s $(pwd)/tf-profile /usr/local/bin  # Optional: only if you want to run tf-profile from other directories
tf-profile --help

Basic Usage

Now that you have set up tf-profile, let’s dive into basic usage. The tool can handle both standard input and log files. Here are two equivalent commands:

terraform apply -auto-approve | tf-profile table

tf-profile table log.txt

Available Commands

tf-profile supports four major commands:

• tf-profile stats: Provides high-level statistics about a Terraform run.
• tf-profile table: Offers detailed, resource-level statistics.
• tf-profile filter: Allows filtering of logs for specific resources.
• tf-profile graph: Generates a visual overview of the Terraform run.

Understanding tf-profile with an Analogy

Think of tf-profile as a data analyst who attends your Terraform operations. When you run a Terraform command, this analyst observes the process closely and takes notes. At the end, they compile their observations into a detailed report:

• tf-profile stats is like a summary report, summarizing key details like the number of resources managed and total execution time.
• tf-profile table acts as an itemized receipt, detailing every resource’s status, operations performed, and timings.
• tf-profile filter enables the analyst to focus on specific entries, just like filtering out other transactions from your shopping list.
• tf-profile graph provides a visual Gantt chart, similar to an infographic showing timelines and dependencies between your resources.

Troubleshooting Tips

While working with tf-profile, you might encounter some issues. Here are some troubleshooting ideas:

• Command Not Found: Ensure that tf-profile is correctly installed and is located on your $PATH.
• Log File Issues: Verify that the log file you are using has read permissions and is in the correct format.
• Docker Issues: If using Docker, ensure that the Docker daemon is running and you have the correct permissions.
