ansible playbook example

Following is a sort example of how to have a playbook and how to run the same. Note that I have already define the hosts details in the inventory file.


amit@laptop:~/ansible-playbook$ cat playbook.yaml
---
- name: install and start nginx
  hosts: vgbox
  user: vagrant
  sudo: yes

  tasks:
  - name: install subversion
    apt: pkg=subversion state=installed

  - name: install nginx
    apt: pkg=nginx state=installed update_cache=true
    notify:
      -  start nginx

  handlers:
    - name: start nginx
      service: name=nginx state=started


## To run the play-book:

$ ansible-playbook playbook.yaml

PLAY [install and start nginx] ************************************************

GATHERING FACTS ***************************************************************
ok: [vg2]
ok: [vg3]
ok: [vg4]




TASK: [install subversion] ****************************************************
changed: [vg2]
changed: [vg4]
changed: [vg3] 
 TASK: [install nginx] *********************************************************
changed: [vg2]
changed: [vg3]
changed: [vg4]


NOTIFIED: [start nginx] *******************************************************
changed: [vg2]
changed: [vg3]
changed: [vg4]

PLAY RECAP ********************************************************************
vg2                        : ok=4    changed=3    unreachable=0    failed=0  
vg3                        : ok=4    changed=3    unreachable=0    failed=0  
vg4                        : ok=4    changed=3    unreachable=0    failed=0  


NOTE: I have the ssh key in my config file, else you can update those details at the inventory file [ default: /etc/ansible/hosts: ]

[vgbox]
vg2
vg3
vg4


## ssh config example:

Host vg2
    HostName 192.168.0.32
    Port 22
    User vagrant
    IdentityFile ~/.vagrant.d/insecure_private_key

Host vg3
    HostName 192.168.0.33
    Port 22
    User vagrant
    IdentityFile ~/.vagrant.d/insecure_private_key

Host vg4
    HostName 192.168.0.34
    Port 22
    User vagrant
    IdentityFile ~/.vagrant.d/insecure_private_key
