Repository description

This repo contains a test deployement of a aws lambda function using:

• terraform (Infrastructure as Code)
• poetry (Package manager)

🐛 For developement

Tool list

• pyenv (Python Installation Management)
• virtualenvWrapper (VirtualEnv wrapper to manage python virtual env when developping)
• poetry (projects specification and package dependency management)
• pip (local package manager)

🔧 How to

Add pip packages to poetry

pip freeze > requirements.txt
poetry add $(cat requirements.txt)

⚠️ When using virtualenvwrapper pip may include package that are not necessary for your project

Deploy your lambda function to AWS

To simplify (using Makefile): run make redeploy-lambda

Package the lambda function

⚠️ Execute these commands from the root of the repo (beware of python version if you reuse)

rm -rf package
mkdir package
cp -R $$(poetry env info -p)/lib/python3.9/site-packages* package/
cp -R ./src/ ./package

Provision with Terraform

❗ Don't forget to define your AWS env. variables from the CLI or bysource a .sh file. Example:

source ./set-env.sh

with a file that looks like

export AWS_ACCESS_KEY_ID="<AWS_ACCESS_KEY_ID>"
export AWS_SECRET_ACCESS_KEY="<AWS_ACCESS_KEY>"

To deploy the terraform config

cd ./tf/
source ./set-env.sh;
terraform plan

Validate the deployement and run (do this after packaging your lambda function with poetry)

terraform apply
