  • To grasp the basic concepts of Ansible.
  • To be able to run Ad hoc commands, on demand.
  • To create a playbook to manage a set of servers with predefined rules.

Outline

Ansible is a an agentless orchestration tool which does more or less what Puppet and Chef do. It relies on OpenSSH for transport and YAML for creating playbooks.
Playbook is essentially a list of rules which are applied to a (set of) server to put them in desired configuration.

In this talk, I will show how to execute ad hoc commands on one or more servers as well as create simple playbooks. I will also talk about the best practices to use Ansible in order to get maximum benefit out of it.

Lastly I will share our own story where Ansible really helped us in deploying Virtualization (Xen) Servers vs Puppet whose compatibility gave us really hard time.
