Contributing To Java Operator SDK

Firstly, big thanks for considering contributing to the project. We really hope to make this into a community project and to do that we need your help!

Code of Conduct

We are serious about making this a welcoming, happy project. We will not tolerate discrimination, aggressive or insulting behaviour.

To this end, the project and everyone participating in it is bound by the Code of Conduct. By participating, you are expected to uphold this code. Please report unacceptable behaviour to any of the project admins or adam.sandor@container-solutions.com.

Bugs

If you find a bug, please open an issue! Do try to include all the details needed to recreate your problem. This is likely to include:

The version of the Operator SDK being used
The exact platform and version of the platform that you're running on
The steps taken to cause the bug

Building Features and Documentation

If you're looking for something to work on, take look at the issue tracker, in particular any items labelled good first issue. Please leave a comment on the issue to mention that you have started work, in order to avoid multiple people working on the same issue.

If you have an idea for a feature - whether or not you have time to work on it - please also open an issue describing your feature and label it "enhancement". We can then discuss it as a community and see what can be done. Please be aware that some features may not align with the project goals and might therefore be closed. In particular, please don't start work on a new feature without discussing it first to avoid wasting effort. We do commit to listening to all proposals and will do our best to work something out!

Once you've got the go ahead to work on a feature, you can start work. Feel free to communicate with team via updates on the issue tracker or the Discord channel and ask for feedback, pointers etc. Once you're happy with your code, go ahead and open a Pull Request.

Pull Request Process

First, please format your commit messages so that they follow the conventional commit format.

On opening a PR, a GitHub action will execute the test suite against the new code. All code is required to pass the tests, and new code must be accompanied by new tests.

All PRs have to be reviewed and signed off by another developer before being merged to the master branch. This review will likely ask for some changes to the code - please don't be alarmed or upset at this; it is expected that all PRs will need tweaks and a normal part of the process.

The PRs are checked to be compliant with the Java Google code style.

Be aware that all Operator SDK code is released under the Apache 2.0 licence.

Development environment setup

Code style

The SDK modules and samples are formatted to follow the Java Google code style. On every compile the code gets formatted automatically, however, to make things simpler (i.e. avoid getting a PR rejected simply because of code style issues), you can import one of the following code style schemes based on the IDE you use:

for Intellij IDEA install google-java-format plugin
for Eclipse follow these intructions
