Serverless Python Project Skeleton

PyPI GitHub Actions

Package skeleton for a Python Serverless project on AWS Lambda.

Description

Bootstrap a new Python Serverless project in five minutes or less.

Features

Bootstrapping a New Project

  1. Create an empty (non-initialized) repository on GitHub.

  2. Clone the master branch of this repository with

    $ git clone --single-branch https://github.com/makenew/serverless-python.git new-serverless-python
$ cd new-serverless-python

    Optionally, reset to the latest release with

    $ git reset --hard <version-tag>

  3. Run

    $ ./makenew.sh

    This will replace the boilerplate, delete itself, remove the git remote, remove upstream tags, and stage changes for commit.

  4. Create the required GitHub repository secrets

  5. Review, commit, and push the changes to GitHub with

    $ git diff --cached
$ git commit -m "Replace makenew boilerplate"
$ git remote add origin [email protected]:<user>/<new-serverless-python>.git
$ git push -u origin master

  6. Ensure the GitHub action passes, then release the initial version with

    $ npm install
$ poetry install
$ poetry version patch
$ make version

Updating

If you want to pull in future updates from this skeleton, you can fetch and merge in changes from this repository.

Add this as a new remote with

$ git remote rename origin upstream

and then configure your origin branch as normal.

Otherwise, add this as a new remote with

$ git remote add upstream [email protected]:makenew/serverless-python.git

You can then fetch and merge changes with

$ git fetch --no-tags upstream
$ git merge upstream/master

Changelog

Note that CHANGELOG.md is just a template for this skeleton. The actual changes for this project are documented in the commit history and summarized under Releases.

Installation

This package is registered on the Python Package Index (PyPI) as makenew-serverless-python.

Install it with

$ poetry add makenew-serverless-python

Development and Testing

Quickstart

$ git clone https://github.com/makenew/serverless-python.git
$ cd serverless-python
$ poetry install

Run each command below in a separate terminal window:

$ make watch

Primary development tasks are defined in the Makefile.

Source Code

The source code is hosted on GitHub. Clone the project with

$ git clone https://github.com/makenew/serverless-python.git

Requirements

You will need Python 3 and Poetry and Node.js with npm. To run some Serverless commands you will need Docker.

Install the development dependencies with

$ poetry install
$ npm install

Tests

Lint code with

$ make lint

Run tests with

$ make test

Run tests on changes with

$ make watch

Publishing

Use the poetry version command to release a new version. Then run make version to commit and push a new git tag which will trigger a GitHub action.

Publishing may be triggered using a version workflow_dispatch on GitHub Actions.

Deployment

Serverless deployment is triggered by a release repository_dispatch on GitHub Actions.

Deployment may be triggered using a release workflow_dispatch on GitHub Actions.

GitHub Actions

GitHub Actions should already be configured: this section is for reference only.

The following repository secrets must be set on GitHub Actions.

  • PYPI_API_TOKEN: API token for publishing on PyPI.
  • AWS_DEFAULT_REGION: The AWS region Serverless will deploy to.
  • AWS_ACCESS_KEY_ID: AWS access key ID.
  • AWS_SECRET_ACCESS_KEY: AWS secret access key.
  • GH_TOKEN: A personal access token that can trigger workflows.

These must be set manually.

Secrets for Optional GitHub Actions

The version and format GitHub actions require a user with write access to the repository. including access to trigger workflows. Set these additional secrets to enable the action:

  • GH_TOKEN: A personal access token for the user.
  • GIT_USER_NAME: The name to set for Git commits.
  • GIT_USER_EMAIL: The email to set for Git commits.
  • GPG_PRIVATE_KEY: The GPG private key.
  • GPG_PASSPHRASE: The GPG key passphrase.
