Hi Shellers (people who use only shell command)

Many thanks for your support in my last post :

Today I want to ask you one question.

Why you don't use Ansible ?

For the newbie, Ansible is a tool to set infrastructure with configuration file, the most efficient thing about it it's the powerfull to setup many server with one command line.

exemple:

You should deploy 1 server with a webserver configuration, and another server with a bdd configuration.

Without ansible you will connect to the ssh tunel inside each server and set the command line associated to her configuration.
BUT !

If you do deploy :

Webserver:

• 3 servers:
  -- 1 prod
  -- 1 preprod
  -- 1 backup

• 3 databases:
  -- 1 prod
  -- 1 preprod
  -- 1 backup

You will connect to the 6 servers and set manually the configuration ?
Too repetitive...

So ..
Ansible with an Inventory can do this for you exemple

Inventory.ini

[webservers]
server1-prod
server2-preprod
server3-backup
# Should be IP or domain

[databases]
db1-prod
db2-preprod
db3-backup
# Should be IP or domain

Here is the set of all your servers ip or domain.

Now you can easy execute a command with an Ansible Playbook.

Ansible Playbook Exemple

Playbook.yml

---
- name: Ansible Playbook Exemple
  host: webservers
  tasks:
    name: Update apt package registry
    command: apt-get update

    name: Install PHP
    command: apt-get install php

if you launch this command:
ansible-playbook playbook.yml -i inventory.ini -v

You will Update Package Registry and install PHP on all webservers at the same time.

Awesome no ?

So go learn and code your infrastructure 💪
