- Full talk
- Technical level
- 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.
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.

I have been a speaker at FUDCon Pune, FUDCon Kuala Lumpur, NELF Boston, GNUnify Pune and have delivered talks on Puppet, Git, infrastructure scalability and various other topics.
