Ansible Concepts Javier López López | PHPConMX 2016 Modules Ansible ships with a number of modules (called the ‘module library’) that can be executed directly on remote hosts or through Playbooks. Users can also write their own modules. These modules can control system resources, like services, packages, or files (anything really), or handle executing system commands. http://docs.ansible.com/ansible/list_of_all_modules.html ‣ MySQL ‣ Redis ‣ Mongo ‣ Copy ‣ Replace ‣ RabbitMQ ‣ Azure ‣ CloudFormation Amazon ‣ Composer ‣ Amazon EC2 ‣ Git ‣ New Relic ‣ Amazon S3 ‣ Etc…….. 

Ansible Concepts Javier López López | PHPConMX 2016 Playbook Playbooks are Ansible’s configuration, deployment, and orchestration language. They can describe a policy you want your remote systems to enforce, or a set of steps in a general IT process. http://docs.ansible.com/ansible/playbooks.html

Ansible Roles Javier López López | PHPConMX 2016 Roles in Ansible build on the idea of include files and combine them to form clean, reusable abstractions – they allow you to focus more on the big picture and only dive down into the details when needed http://docs.ansible.com/ansible/playbooks_roles.html
