Bootstrap Nodes with Python using Ansible

As Ansible depends on Python, Python is needed for using Ansible. To bootstrap nodes with Python, you can use the following Playbook:

Inventory

inventory.ini

[admin]
localhost

[new]
docker-node-1
glusterfs-node-1
glusterfs-node-2
elasticsearch-node-1
elasticsearch-node-2

[admin:vars]
location_country="South Africa"
location_city="Cape Town"

[new:vars]
ansible_python_interpreter=/usr/bin/python3
location=europe

Playbook

bootstrap-python.yml

---
- hosts: all
  gather_facts: False

  tasks:
  - name: install python
    raw: test -e /usr/bin/python || ( apt update && apt install python -y )

  - name: install htop
    raw: test -e /usr/bin/htop || ( apt update && apt install htop -y )

Running Ansible

$ ansible-playbook -i inventory.ini bootstrap-python.yml
