Development environment

Ready to contribute? Here’s how to set up ansible_rulebook for local development:

1. Fork the ansible_rulebook repo on GitHub.

2. Clone your fork locally

git clone git@github.com:your_name_here/ansible-rulebook.git

3. We use a rules engine called Drools which is written in Java. From our python code we directly call the Drools Java classes using JPY. The following criteria must be met for JPY to work correctly:

   • Java 17+ installed

   • Maven 3.8.1+ installed, might come bundled in some Java installs

   • Environment variable JAVA_HOME set accordingly if you want to use a specific Java version different from the default one

4. Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:

cd ansible_rulebook/
python3.9 -m venv venv
source venv/bin/activate
pip install -e .
pip install -r requirements_dev.txt
ansible-galaxy collection install ansible.eda

5. Create a branch for local development:

git checkout -b name-of-your-bugfix-or-feature

Now you can make your changes locally.

6. When you’re done making changes, check that your changes pass flake8 and the tests, including testing other Python versions with tox:

flake8 ansible_rulebook tests
pytest
tox

To get flake8 and tox, just pip install them into your virtualenv.

7. Commit your changes and push your branch to GitHub:

git add .
git commit -m "Your detailed description of your changes."
git push origin name-of-your-bugfix-or-feature

8. Submit a pull request through the GitHub website.

Building the container image

The dockerfile points to the required collection of ansible which provides source plugins.

docker build -t localhost/ansible-rulebook:dev .

Git pre-commit hooks (optional)

To automatically run linters and code formatter you may use git pre-commit hooks. This project provides a configuration for pre-commit framework to automatically setup hooks for you.

1. First install the pre-commit tool:

1. Into your virtual environment:

   pip install pre-commit
   

2. Into your user directory:

   pip install --user pre-commit
   

3. Via pipx tool:

   pipx install pre-commit
   

2. Then generate git pre-commit hooks:

pre-commit install

You may run pre-commit manually on all tracked files by calling:

pre-commit run --all-files

Tips

To run a subset of tests:

pytest tests.test_ansible_rulebook

To run E2E tests

pytest -m e2e

To run Temporal tests

pytest -m temporal

To skip running Temporal tests

pytest -m "not temporal"

Building

python -m build
twine upload dist/*
