setup python venv

Setup a venv the easy way.

sudo apt-get update
sudo apt-get install python3-dev libffi-dev gcc libssl-dev
sudo apt install python3-venv
mkdir -p /home/tseed/ansible/venv
python3 -m venv /home/tseed/ansible/venv
source /home/tseed/ansible/venv/bin/activate

setup ansible environment

install additional ansible galaxy collection

ansible-galaxy collection install community.general

record collections file for replicating this environment

nano -cw requirements.yml

collections:
- name: community.general

install requirements from file on new environment

ansible-galaxy collection install -r requirements.yml
ansible-galaxy collection install community.general --upgrade

dnf install sshpass / apt-get install sshpass
pip install jmespath

run playbook

start venv

source /home/tseed/ansible/venv/bin/activate

run hypervisor build playbook

This only builds hypervisors up to Ceph RBD, VM provisioning not complete

ansible-playbook bootstrap_hypervisors.yml

run dynamic roles from XCAT inventory for the various provisioned VMs

Used in production stack to provision various node classes, there are no real roles in this repo - just framework stuff and ntp/os_packages

ansible-playbook -l all site.yml
