Role Name

This is a simple test repo using the molecule framework for deploying system state via ansible and validating that state using infratest.

Requirements

The following packages should be installed via pip in order to run molecule. In order to isolate the dependencies, it is recommended that you use a python virtualenv. However, such a virtualenv must be located outside of the directory structure of this repo or the ansible linter will attempt to verify the dynamic yaml inside of core ansible and fail spectacularly because the entire virtualenv directory will be in scope for lint inspection.

Here are the basic steps to get started with this repo:

cd /path/where/the/repo/will/be/cloned/to
virtualenv --python python2 venv-molecule
. venv-molecule/bin/activate
pip install molecule testinfra ansible docker-py
git clone [email protected]:johnduarte/molecule-ntp
cd molecule-ntp
molecule test

This branch uses docker as its driver, so docker must be installed on the system running molecule.

Role Variables

A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.

Dependencies

A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: servers
  roles:
     - { role: molecule-ntp, x: 42 }

Generate Molecule Config from Ansible Dynamic Inventory

The moleculerize.py script will build molecule config files from a RPC-O Ansible dynamic inventory file. As a prerequisite to using the moleculerize.py script a dynamic inventory must be generated from a RPC-O build:

sudo su -
cd /opt/openstack-ansible/playbooks/inventory
./dynamic_inventory.py > /path/to/dynaic_inventory.json

Now you can generate a molecule.yml config file using the moleculerize.py script:

cd /path/to/molecule-ntp
./moleculerize.py /path/to/dynaic_inventory.json

The above command assumes that the templates/molecule.yml.j2 template will be used along with molecule.yml as the output file.
