lambda-builder

Use sam to build your lambda into a lambda.zip without installing and setting up sam yourself. Handy for running in a CI environment where docker is available but sam is not.

This runs sam build --use-container in order to build lambdas that require system dependencies. For more details on this, see the AWS docs.

This script does not provide any capabilities with sam local invoke to run your lambda locally; it merely produces a lambda.zip that is suitable for uploading to AWS.

Requirements

  • Docker

Installation

git clone https://github.com/nsidc/lambda-builder

Usage

/path/to/lambda-builder/build.sh relative-or-absolute/path/to/lambda/directory

Docker notes

sam uses Docker, and build.sh starts up a Docker container that runs sam, and sam uses a Docker container for a build environment matching AWS, but this is not Docker-in-Docker; the Docker socket is mounted so that sam has access to the "host Docker".
