How to Bootstrap Nodes With Python Using Ansible

As Ansible depends on Python, therefore we can bootstrap our nodes with Python using a Ansible Playbook

Inventory

The nodes we want to bootstrap:

inventory.ini
1
2
3
4
5
6
7

[new]
node-1
node-2
node-3

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

Playbook

Our playbook with what we want to do:

bootstrap-python.yml
1
2
3
4
5
6
7

---
- hosts: all
  gather_facts: False

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

Deploy

Deploy with Ansible:

1
2
3
4
5
6
7
8
9
10
11
12
13

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

PLAY [all] ***********************************************************************************************************************************************************************************************

TASK [install python] ************************************************************************************************************************************************************************************
changed: [node-1]
changed: [node-2]
changed: [node-3]

PLAY RECAP ***********************************************************************************************************************************************************************************************
node-1                     : ok=2    changed=2    unreachable=0    failed=0
node-2                     : ok=2    changed=2    unreachable=0    failed=0
node-3                     : ok=2    changed=2    unreachable=0    failed=0
