How to contribute

Overview

This document explains the processes and practices recommended for contributing enhancements to the Pollen operator.

• Generally, before developing enhancements to this charm, you should consider opening an issue explaining your use case.
• If you would like to chat with us about your use-cases or proposed implementation, you can reach us at Canonical Mattermost public channel or Discourse.
• Familiarising yourself with the Charmed Operator Framework library will help you a lot when working on new features or bug fixes.
• All enhancements require review before being merged. Code review typically examines
  • code quality
  • test coverage
  • user experience for Juju operators of this charm.
• Please help us out in ensuring easy to review branches by rebasing your pull request branch onto the main branch. This also avoids merge commits and creates a linear Git commit history.
• Please generate src documentation for every commit. See the section below for more details.

Developing

The code for this charm can be downloaded as follows:

git clone https://github.com/canonical/pollen-operator

You can use the environments created by tox for development:

tox --notest -e unit
source .tox/unit/bin/activate

Testing

The following commands can then be used to run the tests:

• tox: Runs all of the basic checks (lint, unit, static, and coverage-report).
• tox -e fmt: Runs formatting using black and isort.
• tox -e lint: Runs a range of static code analysis to check the code.
• tox -e static: Runs other checks such as bandit for security issues.
• tox -e unit: Runs the unit tests.
• tox -e integration: Runs the integration tests.

Generating src docs for every commit

Run the following command:

echo -e "tox -e src-docs\ngit add src-docs\n" >> .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit

Build charm

Build the charm in this git repository using:

charmcraft pack

Deploy

# Create a model
juju add-model pollen-dev
# Enable DEBUG logging
juju model-config logging-config="<root>=INFO;unit=DEBUG"
