If you need compiled binaries you can use Amazon Machine Images (AMI) to spin up an EC2 instance (or use this easy docker container), compile your own binaries, and copy them over to your project. The project repository already contains the binaries you can use.
A client recently requested a feature involving screenshots of random URLs. Now, there are several services out there that will do this for you. Most of these services have interesting REST APIs and pricing models, but I really wanted to develop something with Serverless. So I took this opportunity to check it out.
For this project we will need some extra binaries ( PhantomJS in particular) to take the screenshots. We’ll also use ImageMagick, but that is provided by AWS by default in the Lambda image, so we don’t package it separately.
We use the stage-variables plugin so we can set stage variables in API Gateway, which we can then use in our Lambda functions. You can configure them in the custom section. This also allows us to use CloudFormation references inside our Lambda functions. CloudFormation will fill in the values with the actual output for us.
