How to contribute §

k8gb is Apache 2 licensed and accepts contributions via GitHub pull requests. This document outlines some of the conventions on commit message formatting, contact points for developers, and other resources to help get contributions into k8gb project.

Slack chat §

Find us at #sig-multicluster on kubernetes.slack.com

Getting started §

Fork the repository on GitHub
See the local playground guide for testing environment setup

Reporting bugs and creating issues §

Reporting bugs is one of the best ways to contribute. Feel free to open an issue describing your problem or any question.

Contribution flow §

This is a rough outline of what a contributor's workflow looks like:

Create a topic branch from where to base the contribution.
Make commits of logical units.
Make sure commit messages are in the proper format (see below).
Push changes in a topic branch to a personal fork of the repository.
Submit a pull request to AbsaOSS/k8gb.
The PR must receive a LGTM from two maintainers found in the CODEOWNERS file.

Thanks for contributing!

Local setup §

make deploy-full-local-setup

Deploys k8gb from scracth including:

2 local clusters
Stable k8gb helm chart
Gslb Custom Resources examples
Test applications

make upgrade-candidate

Performs upgrade of k8gb helm chart and controller to the testing version that is built from your current development tree.

Testing §

Unit tests should be updated for any functional code change at test suite location.
Acceptance terratest suite is located here and executable by make terratest target. These tests are changed only if the change is substantial enough to affect the main end-to-end flow.

Debugging

Debugging §

Delve debugger needs to be installed first. Follow the installation instructions for specific platforms from Delve's website.

Run the following script

> make debug-local

Attach debugger of your favourite IDE to port 2345.

Code style §

The coding style suggested by the Golang community is used in k8gb project. See the style doc for details.

Please follow this style to make k8gb easy to review, maintain and develop.

Run make lint to automatically check if your code is compliant.

Format of the commit message §

We follow a rough convention for commit messages that are designed to answer two questions: what changed and why. The subject line should feature the what and the body of the commit should describe the why.

scripts: add the test-cluster command

this uses tmux to setup a test cluster that can easily be killed and started for debugging.

Fixes #38

The format can be described more formally as follows:

<subsystem>: <what changed>
<BLANK LINE>
<why this change was made>
<BLANK LINE>
<footer>

The first line is the subject and should be no longer than 70 characters, the second line is always blank, and other lines should be wrapped at 80 characters. This allows the message to be easier to read on GitHub as well as in various git tools.

Documentation §

If the contribution changes the existing APIs or user interface it must include sufficient documentation to explain the use of the new or updated feature. CHANGELOG is automatically generated from Github PRs and Issues. Please use special keywords to link PR to and Issue for a clean changelog generation.
