Lambda Function Packager

A Go-based tool to package AWS Lambda functions along with their dependencies into zip files.

Features

• Automatically packages Lambda functions and their dependencies into zip files
• Supports multiple Lambda functions
• Uses viper for configuration management
• Provides a command-line interface using cobra

Installation

Option 1: Go Install

If you have Go installed on your system, you can use go install to install the Lambda Function Packager.

1. Run the following command: go install github.com/4cecoder/lamdazip@latest

2. The lamdazip executable will be installed in your $GOPATH/bin directory.

Option 2: Manual Installation

1. Clone the repository: git clone https://github.com/4cecoder/lamdazip.git

2. Change into the project directory: cd lamdazip

3. Build the executable: go build

Configuration

The Lambda Function Packager uses a configuration file to specify the Lambda function names, site-packages directory, and destination directory. By default, it looks for a configuration file named .lambda-packager.yaml in the user's home directory.

Here's an example configuration file:

function_names:
- cold_rail
- new_customer
- updated_customer
site_packages_dir: venv/Lib/site-packages
dest_dir: terraform/dev/lambda

function_names: An array of Lambda function names to be packaged.
site_packages_dir: The directory path of the virtual environment's site-packages.
dest_dir: The destination directory where the packaged Lambda functions will be moved.

You can create a configuration file with a different name or location and specify its path using the --config flag when running the tool. Usage:`

If you want to use a different configuration file, specify its path using the --config flag:

./lamdazip --config path/to/config.yaml

To package Lambda functions, run the following command:

./lamdazip

The tool will package each Lambda function specified in the configuration file along with its dependencies into separate zip files. The zip files will be moved to the corresponding directories under the specified destination directory. Project Structure

main.go: The main Go file containing the Lambda Function Packager logic.
.lambda-packager.yaml: The default configuration file.
funx/: Directory containing the Lambda function files.
terraform/dev/lambda/: The destination directory for the packaged Lambda functions.

Dependencies

The Lambda Function Packager uses the following dependencies:

github.com/spf13/cobra: A library for creating powerful modern CLI applications.
github.com/spf13/viper: A complete configuration solution for Go applications.

Make sure to have these dependencies installed before running the tool. Contributing
