Ansible : Use Playbook#12015/04/22

 
This is the basic usage of Ansible Playbook.
Playbook is written as YAML file.
[1] For example, create a Playbook which a file exists with the same permission.
[cent@dlp ~]$
vi playbook_sample.yml
# target hostname or group name

- hosts: target_servers
# define tasks

  tasks:
# task name (any name you like)

  - name: Test Task
# use file module to set the file state

    file: path=/home/cent/test.conf state=touch owner=cent group=cent mode=0600
# run Playbook

[cent@dlp ~]$
ansible-playbook playbook_sample.yml
