Requirements

This repository should be used from a Python Virtual Environment.

Setup Python 3

Make sure versions are up-to-date and install git and ssh server:

sudo apt update
sudo apt -y upgrade

Check Python version:

python3 -V

Install essential tools for the development environment:

sudo apt install -y python3-pip build-essential libssl-dev libffi-dev python3-dev python3-venv git ssh

Setup Virtual Environment

Create the Virtual Environment:

git clone https://github.com/bcochofel/ansible-ubuntuwst-roles.git
cd ansible-ubuntuwst-roles
python3 -m venv .venv

Activate the environment:

source .venv/bin/activate

Install requirements.txt:

pip install --upgrade setuptools wheel pip
pip install -r requirements.txt

Install community.general collection for Ansible:

ansible-galaxy collection install community.general

You now have python virtual environment with all the dependencies installed and can start deploying the ansible roles.

Configure Ansible

You should have ssh installed and running.

Create SSH key:

ssh-keygen -t rsa

and add the public key to ~/.ssh/authorized_keys:

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

Ensure sudo passwordless for the ansible user by creating a file /etc/sudoers.d/bcochofel with the following contents:

bcochofel ALL=(ALL) NOPASSWD: ALL

and that the file permissions are 0440.

Install Ansible and Molecule manually

If you don't want to use the requirements.txt file you can install both ansible and molecule using the following commands:

python3 -m pip install wheel pytest testinfra flake8 pytest-testinfra pytest-flake8 cookiecutter
python3 -m pip install "molecule[ansible,lint,docker]"
# for snap module
ansible-galaxy collection install community.general

generate requirements.txt file using the following command:

pip freeze > requirements.txt

Create new Ansible Role
