Test AWS Lambda functions locally

An easy way to run an AWS Lambda function with the Sentry SDK locally.

This is a small helper to create a AWS Lambda function that includes the currently checked out Sentry SDK and runs it in a local AWS Lambda environment.

Currently only embedding the Sentry SDK into the Lambda function package is supported. Adding the SDK as Lambda Layer is not possible at the moment.

Prerequisites

  • Set SENTRY_DSN environment variable. The Lambda function will use this DSN.
  • You need to have Docker installed and running.

Run Lambda function

  • Update lambda_function.py to include your test code.
  • Run ./deploy-lambda-locally.sh. This will:
    • Install AWS SAM in a virtual Python environment
    • Create a lambda function package in package/ that includes
      • The currently checked out Sentry SDK
      • All dependencies of the Sentry SDK (certifi and urllib3)
      • The actual function defined in lamdba_function.py.
    • Zip everything together into lambda_deployment_package.zip
    • Run a local Lambda environment that serves that Lambda function.
  • Point your browser to http://127.0.0.1:3000 to access your Lambda function.
    • Currently GET and POST requests are possible. This is defined in template.yaml.
