An example AWS Lambda written in GoLang to tag a picture with its prominent colors

This repository implements an AWS Lambda using Go that allows you to tag JPEG images in an S3 bucket with their prominent colors from a given palette.

The goal of this project is to act as a tutorial to learn how to build, test and deploy AWS Lambdas written in Go.

This work is kindly sponsored by Buddy.works.

In order to run this example you need:

• Go (1.12+)
• Terraform (0.11+)
• Docker (18.09+)
• Docker-compose (1.23+)
• GNU make
• An AWS account (with AWS cli installed and configured)

• Lambda source code can be found in cmd/image-colors-lambda
• Terraform code for stack definition can be found in stack
• Integration tests (using docker-compose) can be found in tests

To test the application you can run:

make test

This will run:

• Linting checks
• Unit tests
• Integration tests

In order to deploy this solution to your default AWS account you can run:

make deploy
