quiltdata/lambda repository overview

⁠Build AWS Lambda deployment packages with Docker

⁠Why?

• Logging in to EC2 and creating a deployment package by hand⁠ is clumsy
• Instead, script package creation around the amazonlinux image⁠ (blessed as an official repository and linked from this AWS user guide⁠)

⁠Example: Python 3.6 deployment package

docker pull quiltdata/lambda

docker run --rm -v $(pwd)/create_table:/io -t \
	-e SETUP_DIR -e GIT_REPO quiltdata/lambda \
	bash /io/package.sh

• Mount /io as a docker volume
  • /io should contain package.sh and your lambda code \
  • /io is where the deployment package, lambda.zip, is written \
• Pass environment variables with -e
• --rm so that, for example, secure envs aren't written to disk

⁠Customize

Modify package.sh to suit your own purposes.

⁠Build container

docker build -t quiltdata/lambda .

⁠Clone private GitHub repo in container

Use a personal access token⁠:

git clone https://${TOKEN}@github.com/USER/REPO

⁠Optimizations to reduce .zip size

Possible but not tried in this repo:

• Delete *.py⁠
• Profile code and only retain files that are used⁠
