Contributing Guidelines

Some basic conventions for contributing to this project.

General

Please make sure that there aren't existing pull requests attempting to address the issue mentioned. Likewise, please check for issues related to update, as someone else may be working on the issue in a branch or fork.

Please open a discussion in a new issue / existing issue to talk about the changes you'd like to bring
Develop in a topic branch, not master/develop

When creating a new branch, prefix it with the type of the change (see section Commit Message Format below), the associated opened issue number, a dash and some text describing the issue (using dash as a separator).

For example, if you work on a bugfix for the issue #361, you could name the branch fix361-template-selection.

Issues open to contribution

Want to contribute but don't know where to start?

Some of the open issues are labeled with prefix exp/, this is used to mark them as available for contributors to work on. All of these have an attributed difficulty level:

beginner: a task that should be accessible with users not familiar with the codebase
intermediate: a task that require some understanding of the project codebase or some experience in either AngularJS or Golang
advanced: a task that require a deep understanding of the project codebase

You can have a use Github filters to list these issues:

beginner labeled issues: https://github.com/portainer/portainer/labels/exp%2Fbeginner
intermediate labeled issues: https://github.com/portainer/portainer/labels/exp%2Fintermediate
advanced labeled issues: https://github.com/portainer/portainer/labels/exp%2Fadvanced

Linting

Please check your code using grunt lint before submitting your pull requests.

Commit Message Format

Each commit message should include a type, a scope and a subject:

 <type>(<scope>): <subject>

Lines should not exceed 100 characters. This allows the message to be easier to read on github as well as in various git tools and produces a nice, neat commit log ie:

 #271 feat(containers): add exposed ports in the containers view
 #270 fix(templates): fix a display issue in the templates view
 #269 style(dashboard): update dashboard with new layout

Type

Must be one of the following:

feat: A new feature
fix: A bug fix
docs: Documentation only changes
style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
refactor: A code change that neither fixes a bug or adds a feature
test: Adding missing tests
chore: Changes to the build process or auxiliary tools and libraries such as documentation generation

Scope

The scope could be anything specifying place of the commit change. For example networks, containers, images etc... You can use the area label tag associated on the issue here (for area/containers use containers as a scope...)

Subject

The subject contains succinct description of the change:

use the imperative, present tense: "change" not "changed" nor "changes"
don't capitalize first letter
no dot (.) at the end
