Before Submitting a Bug Report

How Do I Submit a (Good) Bug Report?

Bugs are tracked as GitHub issues. After you've determined which repository your bug is related to, create an issue on that repository and provide the following information by filling in the issue template here.

Explain the problem and include additional details to help maintainers reproduce the problem:

  • Use a clear and descriptive title for the issue to identify the problem
  • Describe the exact steps which reproduce the problem in as many details as possible. For example, start by explaining
  • how you started kubectl, e.g. which command you used in the terminal, or how you started Kubesec otherwise
  • Provide specific examples to demonstrate the steps. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets in the issue, use Markdown code blocks
  • Describe the behaviour you observed after following the steps and point out what exactly is the problem with that behaviour
  • Explain which behaviour you expected to see instead and why.

Provide more context by answering these questions:

  • Did the problem start happening recently (e.g. after updating to a new version of Kubesec) or was this always a problem?
  • If the problem started happening recently, can you reproduce the problem in an older version of Kubesec? What's the most recent version in which the problem doesn't happen? You can download older versions of Kubesec from the releases page
  • Can you reliably reproduce the issue? If not, provide details about how often the problem happens and under which conditions it normally happens
  • If the problem is related to scanning files, does the problem happen for all files and projects or only some? Is there anything else special about the files you are using? Please include them in your report, censor any sensitive information but ensure the issue still exists with the censored file

Your First Code Contribution

Unsure where to begin contributing to Kubesec? You can start by looking through these Good First Issue and Help Wanted issues:

Both issue lists are sorted by total number of comments. While not perfect, number of comments is a reasonable proxy for impact a given change will have.

Development

To build the project you can use make build. The resulting binary will be in ./dist.

To test the project you can run make test for unit and make test-acceptance command-line acceptance testing. For http testing also run make test-remote.

Note: The acceptance tests require some dependencies fetched via submodules. You can either clone the repo with --recurse-submodules or it will automatically fetch them if they're missing when running make test-acceptance/make test-remote.

Pull Requests

The process described here has several goals:

  • Maintain Kubesec's quality
  • Fix problems that are important to users
  • Engage the community in working toward the best possible Kubesec
  • Enable a sustainable system for Kubesec's maintainers to review contributions

Please follow these steps to have your contribution considered by the maintainers:

  1. Follow all instructions in the template
  2. Follow the style guides
  3. After you submit your pull request, verify that all status checks are passing
    What if the status checks are failing? If a status check is failing, and you believe that the failure is unrelated to your change, please leave a comment on the pull request explaining why you believe the failure is unrelated. A maintainer will re-run the status check for you. If we conclude that the failure was a false positive, then we will open an issue to track that problem with our status check suite.

While the prerequisites above must be satisfied prior to having your pull request reviewed, the reviewer(s) may ask you to complete additional tests, or other changes before your pull request can be ultimately accepted.
