	Chef puppet salt cfengine

How it works?

HUMAN ---> Ansible Control Server(ACS) ----> Ansible remote server(ARS) (S)
	

ACS			ARS
=====================================
Linux			ANY 
Ansible			NA
	--------------> Windows (Winrm)
	---------------> Linux (SSH)
Python			Linux - python
			windows - dotnet - ps

Component of Ansible in (ACS)
==================================
Ansible
	Executables

		https://docs.ansible.com/ansible/2.9/modules/list_of_all_modules.html
		https://docs.ansible.com/ansible/2.8/modules/modules_by_category.html
	plugins	- Python code - RUN IN ACS -- feature of ansible
	Configfile -- https://github.com/ansible/ansible/blob/stable-2.9/examples/ansible.cfg

Playbook
	Yaml file whcih contains Module which to be run In ARS

Inventory
	a file which has list of IP addre of ARS
						

30 Nov 2023 – Ansible Adhoc Commands

What is Project?
----------------------
Setup a webserver.

Psucode
-----------------
Step 1 - Install webserver	apt
Step 2 - Copy index.html to /var/www/html	copy
Step 3 - Start a  service	service
============================================

ansible localhost -m apt -a"name=apache2 state=latest"
ansible localhost -m copy -a"src=index.html dest=/var/www/html/index.html"
ansible localhost -m service -a"name=apache2 state=started"

Ansible Playbook?
===========================

What is Playbook?
----------------------
	Yaml file
	Contains
		Hosts: localhost | groupname | all
	
		Task(S):
			- Task1 == module and its param
			- task2 == module and its param
			- Task3 == module and its param



Why we need playbook?
================================
	To have all the modules in one file
	Paramterized - 
	Easy to share


ansible web -i inventory -m apt -a"name=apache2 state=latest" -u rajesh -k -b -K
ansible web -i inventory -m copy -a"src=index.html dest=/var/www/html/index.html" -u rajesh -k -b -K
ansible web -i inventory -m service -a"name=apache2 state=started" -u rajesh -k -b -K
