Developing

Build and install locally

Clone the repository, checkout the tag you want to build, or pick the main branch for the development version; then:

ansible-galaxy collection build .
ansible-galaxy collection install middleware_automation-amq-*.tar.gz

Development environment

Make sure your development machine has avilable:

  • python 3.11+

  • virtualenv

  • docker (or podman)

In order to run setup the development environment and run the molecule tests locally, after cloning the repository:

# create new virtualenv using python 3
virtualenv $PATH_TO_DEV_VIRTUALENV
# activate the virtual env
source $PATH_TO_DEV_VIRTUALENV/bin/activate
# install ansible and tools onto the virtualenv
pip install yamllint 'molecule>=6.0' 'molecule-plugins[docker]' 'ansible-core>=2.16' ansible-lint
# install collection dependencies
ansible-galaxy collection install -r requirements.yml
# install python dependencies
pip install -r requirements.txt molecule/requirements.txt
# execute the tests (replace --all with -s subdirectory to run a single test)
molecule test --all

Contributor’s Guidelines

  • All YAML files named with .yml extension

  • Use spaces around jinja variables. {{ var }} over {{var}}

  • Variables that are internal to the role should be lowercase and start with the role name

  • Keep roles self contained - Roles should avoid including tasks from other roles when possible

  • Plays should do nothing more than include a list of roles except where pre_tasks and post_tasks are required when possible

  • Separators - Use valid name, ie. underscores (e.g. my_role my_playbook) not dashes (my-role)

  • Paths - When defining paths, do not include trailing slashes (e.g. my_path: /foo not my_path: /foo/). When concatenating paths, follow the same convention (e.g. {{ my_path }}/bar not {{ my_path }}bar)

  • Indentation - Use 2 spaces for each indent

  • vars/ vs defaults/ - internal or interpolated variables that don’t need to change or be overridden by user go in vars/, those that a user would likely override, go under defaults/ directory

  • All arguments have a specification in meta/argument_specs.yml

  • All playbooks/roles should be focused on compatibility with Ansible Automation Platform
