Getting Started

Follow our Installation Guide to install Ansible and Molecule and get ready to use the NGINX Ansible role.

Project Structure

• The NGINX Ansible role is written in yaml and supports NGINX Open Source, NGINX Plus, and NGINX Amplify.
• The project follows the standard Ansible role directory structure:
  • The main code is found in tasks/.
  • Variables can be found in defaults/main/.
  • "Constant" variables can be found in vars/main.yml.
  • Configuration templates for NGINX can be found in templates/.
  • Molecule tests can be found in molecule/.
  • CI/CD is done via GitHub actions using the workflow files found in .github/workflows/.

Code Guidelines

Ansible Guidelines

• Run molecule lint over your code to automatically resolve a lot of yaml and Ansible style issues.
• Run molecule test on your code before you submit a PR to catch any potential issues. If you are testing a specific molecule scenario, run molecule test -s <scenario>. If you are testing the NGINX Plus scenario (plus), you will need to procure an NGINX Plus license (check out the NGINX Plus developer license FAQ to find out how to request one).
• Follow these guides on some good practices for Ansible:
  • https://www.ansible.com/blog/ansible-best-practices-essentials
  • https://docs.ansible.com/ansible/latest/user_guide/playbooks_best_practices.html

Git Guidelines

• Keep a clean, concise and meaningful git commit history on your branch (within reason), rebasing locally and squashing before submitting a PR.
• Follow the guidelines of writing a good commit message as described here https://chris.beams.io/posts/git-commit/ and summarised in the next few points:
  • In the subject line, use the present tense ("Add feature" not "Added feature").
  • In the subject line, use the imperative mood ("Move cursor to..." not "Moves cursor to...").
  • Limit the subject line to 72 characters or less.
  • Reference issues and pull requests liberally after the subject line.
  • Add more detailed description in the body of the git message (git commit -a to give you more space and time in your text editor to write a good message instead of git commit -am).
