Cloud Provisioning Playbook

Provision AWS EC2 or OpenStack Nova instances with one simple Ansible command and consistent inputs.

Overview

• Inputs: platform (aws|openstack) and flavor (small|medium|large).
• Defaults live in group_vars/all.yml (images, flavors, network, security groups, keys).
• Single entrypoint: site.yml selects the right role per platform.

Install

python -m venv .venv
. .venv/bin/activate
pip install ansible
ansible-galaxy collection install -r requirements.yml

Configure

• AWS: set env vars or aws configure (optionally AWS_PROFILE).
• OpenStack: source ./admin-openrc.sh (WSL/Git Bash on Windows recommended).

Run

• AWS (small):

  ansible-playbook site.yml -i localhost, -c local -e "platform=aws flavor=small"

• OpenStack (medium):

  source ./admin-openrc.sh
  ansible-playbook site.yml -i localhost, -c local -e "platform=openstack flavor=medium"

• Overrides & verbosity:

  ansible-playbook site.yml -i localhost, -c local -e "platform=aws flavor=large aws.region=us-west-2" -vvv
  
  ansible-playbook site.yml -i localhost, -c local -e "platform=openstack flavor=small openstack.key_name=mykey"
