This document discusses Ansible, an agentless automation platform for configuration management, provisioning, and application deployment. It describes how Ansible modules can be used out of the box or customized to perform tasks like package installation, service management, and more. It also provides instructions for developing a custom Ansible module in Python, including module components and executing the module via a playbook.

Contributing to Ansible Developing Ansible Modules
software platform for CM systems Agentless Secure Scalable ....wait a min....what the heck is Ansible?
....so what can we do with ansible? package installation shell commands install/update package management systems, clone git stop, start, re-start service
.....also ansible comes with batteries included!! Ansible comes bundled with nearly all the mostly used applications/protocols etc in computing world. http://docs.ansible.com/list_of_all_modu
...need any thing out of the box?? write down our own custom modules....and the best part...guess??
It's free of any language barrier
....cool...seems interesting, so what are the different components of a module? Though ansible modules can be written in any language, we will stick to Python in this post. In Python, a module is generally a single file with 3 different parts: Documentation: A multiline string literal and a valid YAML document. It contains the detailed description of module. Logic: The programatic way to perform task and uses various resources provided by Ansible. Ansible framework: bunch of basic utilities to perform its tasks, imported by all modules using the following import statement: from ansible.module_utils.basic import *
...let's try bulding some custom modules..
files hosted on github.... https://github.com/hellodk repository : ansible-meetup-bangalore
Basic configurations 1. From the file /etc/ansible/ansible.cfg, uncomment the line library = /usr/share/ansible 2. In the file /etc/ansible/hosts create an entry with 127.0.0.1
...steps to follow 1. Create a new directory inside /usr/share/ansible/ sudo mkdir external 2. Make a new file, inside the external directory sudo vi test_module 3. Now you can write your yml based play-book vi test_playbook.yml
....executing the module via playbook $ ansible-playbook test_yml.yml
