1. ANSIBLE PLAYBOOKS
• Playbooks are text file written in YAML format. Compared to the
languages used in other configuration management tools such
as puppet, the syntax used in playbook is much easier to write
and comprehend.
• In comparison with ad-hoc commands, playbooks are used in
complex scenarios, and they offer increased flexibility.
• Playbooks use YAML format, so there is not much syntax
needed, but indentation must be respected. Ansible playbooks
tend to be more of a configuration language than a
programming language.
• Like the name is saying, a playbook is a collection of plays.
Through a playbook, you can designate specific roles to some of
the hosts and other roles to other hosts. By doing so, you can
orchestrate multiple servers in very diverse scenarios, all in
one playbook.
