TerraLambda CLI Documentation

Overview

TerraLambda is a CLI tool designed to simplify the deployment and invocation of AWS Lambda functions using Terraform. It streamlines the function lifecycle by automating packaging, deployment, and execution processes, providing a seamless experience for developers working with AWS Lambda.

Core concepts

1. Infrastructure as Code (IaC) with Terraform

TerraLambda leverages Terraform to define and manage AWS Lambda functions, ensuring a declarative and reproducible deployment process.

2. AWS Lambda Invocation

• The tool compiles the source code, packages it into a ZIP file, and deploys it using Terraform.
• Manages different versions of Lambda functions to support rollback mechanisms.

3. AWS Lambda Invocation

• Allows invoking deployed Lambda functions via the AWS SDK.
• Supports sending payloads to test functions interactively.

4. Rollback Mechanisms (in progress)

Uses AWS Lambda versioning and aliases to revert to a previous stable version. Integrates Terraform state management to facilitate rollback operations.
