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 <https://github.com/makenew/serverless-python/releases>__ 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 [e-mail]:/.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 [e-mail]: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 <https://github.com/makenew/serverless-python/releases>`__.

Installation
------------

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

Install it with

::

    $ poetry add makenew-serverless-python

.. _makenew-serverless-python: https://pypi.python.org/pypi/makenew-serverless-python
.. _Python Package Index (PyPI): https://pypi.python.org/

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

.. _source code: https://github.com/makenew/serverless-python

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

.. _Docker: https://www.docker.com/ .. _Node.js: https://nodejs.org/ .. _npm: https://www.npmjs.com/ .. _Poetry: https://poetry.eustace.io/ .. _Python 3: https://www.python.org/

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_.

.. _Poetry version: https://python-poetry.org/docs/cli/#version .. _version workflow_dispatch on GitHub Actions: https://github.com/makenew/pypackage/actions?query=workflow%3Aversion

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`_.

.. _release workflow_dispatch on GitHub Actions: https://github.com/makenew/serverless-python/actions?query=workflow%3Arelease

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.

.. _GPG private key: https://github.com/marketplace/actions/import-gpg#prerequisites
