Contributing

Thank you for contributing to OpenShift Ansible. This document explains how the repository is organized, and how to submit contributions.

Introduction

Before submitting code changes, get familiarized with these documents:

Repository structure

Ansible

.
├── inventory           Contains dynamic inventory scripts, and examples of
│                       Ansible inventories.
├── library             Contains Python modules used by the playbooks.
├── playbooks           Contains Ansible playbooks targeting multiple use cases.
└── roles               Contains Ansible roles, units of shared behavior among
                        playbooks.

Ansible plugins

These are plugins used in playbooks and roles:

.
├── ansible-profile
├── callback_plugins
├── filter_plugins
└── lookup_plugins

Scripts

.
├── bin                 [DEPRECATED] Contains the `bin/cluster` script, a
│                       wrapper around the Ansible playbooks that ensures proper
│                       configuration, and facilitates installing, updating,
│                       destroying and configuring OpenShift clusters.
│                       Note: this tool is kept in the repository for legacy
│                       reasons and will be removed at some point.
└── utils               Contains the `atomic-openshift-installer` command, an
                        interactive CLI utility to install OpenShift across a
                        set of hosts.

Building RPMs

See the RPM build instructions.

Running tests

This section covers how to run tests for the root of this repo, running tests for the oo-install wrapper is described in utils/README.md.

We use tox to manage virtualenvs and run tests. Alternatively, tests can be run using detox which allows for running tests in parallel

pip install tox detox

List the test environments available:

tox -l

Run all of the tests with:

tox

Run all of the tests in parallel with detox:

detox

Running a particular test environment (python 2.7 flake8 tests in this case):

tox -e py27-ansible22-flake8

Running a particular test environment in a clean virtualenv (python 3.5 pylint tests in this case):

tox -r -e py35-ansible22-pylint

If you want to enter the virtualenv created by tox to do additional testing/debugging (py27-flake8 env in this case):

source .tox/py27-ansible22-flake8/bin/activate

Submitting contributions

  1. Go through the guides from the introduction.
  2. Fork this repository, and create a work branch in your fork.
  3. Make changes and commit. You may want to review your changes and run tests before pushing your branch.
  4. Open a Pull Request.

One of the repository maintainers will then review the PR and submit it for testing.

The default test job is publicly accessible at https://ci.openshift.redhat.com/jenkins/job/openshift-ansible/. The other jobs are run on a different Jenkins host that is not publicly accessible, however the test results are posted to S3 buckets when complete.

The test output of each job is also posted to the Pull Request as comments.
