ruby-vips-lambda's Introduction

Ruby Libvips Lambda Layer

Lamby: Simple Rails & AWS Lambda Integration using Rack.Are you using the ruby-vips or image_processing gems with a Lambda microservice? Maybe you are using Lamby to deploy your entire Rails application to AWS Lambda with its simple Rack integration? If yes to any of the above, this Lambda Layer is just for you.

Lamby: Simple Rails & AWS Lambda Integration using Rack.

Usage

Ensure you have both Docker installed and your AWS CLI configured. After you clone this repository, please run:

$ ./bin/deploy

This will call ./bin/build for you and push your built Lambda Layer to your own account. Use the ARN in the script's output within your AWS SAM template.yaml file. If needed you can use the AWS_PROFILE environment variable to control which CLI account is used.

Ruby 2.7 or 2.5?

The master branch of this repo is targeted for the Ruby 2.7 runtime which is Amazon Linux 2. Most all dependencies needed for libvips have to be installed and packaged. Please use the ruby25 branch which is Amazon Linux 1 if you use the ruby2.5 runtime.

Node

Technically this layer can be used with Node for the sharp package. Sharp will detect a global libvips installation and use it during the SAM build steps if you use both build from source and set the PKG_CONFIG_PATH to the opt directory. So for example:

PKG_CONFIG_PATH=/opt/lib/pkgconfig npm install --build-from-source

Please reference sharp's installation instructions for full details.

Methodology

Simplicity and small file size! We followed the docs for libvips install. Our build script uses lambci/lambda:build-ruby2.7 Docker image from the docker-lambda project as our build environment. All build commands are located in the Dockerfile which install all the dependencies for libvips in the /opt directory. This includes common file format openers and savers as well as libs that ensure libvips is fast. The current version built is 8.10.0 and easy to configure by providing the VIPS_VERSION environment variable during the build or deploy script.

Alternatives

The Yumda project form Serverless Hero Michael Hart recently added libvips package support. It installs both ImageMagick and Libvips and is an excellent alterative to this project. Check it out!

Current size of the layer's un-compressed contents is around 32MB in size. Contents include:
