Clear Lambda code storage

Motivation

AWS limits the total code storage for Lambda functions to 75GB.

The main reason of reaching such size is because for every deployment of existing function, AWS stores the previous version ("qualifier").

Usually, when you reach that point, you want to remove old version. This tool will help you to!

Setup

git clone https://github.com/epsagon/clear-lambda-storage
cd clear-lambda-storage/
pip install -r requirements.txt
python clear_lambda_storage.py

Advanced usage

Provide credentials:

python clear_lambda_storage.py --token-key-id <access_key_id> --token-secret <secret_access_key>

⚡️ Serverless Framework usage

npm i -g serverless
git clone https://github.com/epsagon/clear-lambda-storage
cd clear-lambda-storage/
serverless deploy

You can schedule this Lambda code storage clean to run every period you want:

functions:
  clear_lambda_storage:
    handler: handler.clear_lambda_storage
    memorySize: 128
    timeout: 120
    events:
      - schedule: cron(0 12 ? * SUN *) # Run every sunday at 12:00pm UTC
