- 3. ● software platform for CM systems ● Agentless ● Secure ● Scalable ....wait a min....what the heck is Ansible?
- 4. ....so what can we do with ansible? ● package installation ● shell commands ● install/update package ● management systems, clone git ● stop, start, re-start service
- 5. .....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
- 6. ...need any thing out of the box?? write down our own custom modules....and the best part...guess??
- 7. It's free of any language barrier
- 8. ....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 *
- 9. ...let's try bulding some custom modules.. ●

- 11. 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
- 12. ...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
- 13. ....executing the module via playbook $ ansible-playbook test_yml.yml
- 15. .....all yours... give a shout for any queries/questions
