Ansible, Centos65, Oracle VirtualBox, Vagrant and Provision

In Agile age, can't wait for environment’s (Development, Test, SIT and Pre-Prod and Prod) in place for start the development and configuration. What we need, just single windows system, where we can start provisioning with below tools and technologies. This will help more in Continues Development CD, Continues Integration CI and Continues Delivery CD.

Need to switch our base tool to vagrant-ansible-centos directory
$ cd C:\vagrant-ansible-centos

$ pwd
/c/vagrant-ansible-centos

$ ls -tlr

inventory
etc
provision.sh

Note: assuming centos65-x86_64-20140116.box has been downloaded under c:\vagrant-ansible-centos

Alternatively, ssh into localhost:2200 or 2222 what ever printed on above
using private key c/vagrant-ansible-centos\.vagrant\machines\default\virtualbox\private_key

$ vagrant ssh

[vagrant@vagrant-centos65 vagrant-ansible-centos]$ ls -tlr

All this files will mount in /vagrant-ansible-centos/ as mentioned in Vagrent file.

Install the Ansible

Is not it simple? For real implementation only we have to change the actual IP address of web server.

C:\vagrant-ansible-centos\inventory\dev

local ansible_ssh_port=2200 ansible_ssh_host=127.0.0.1 ansible_connection=local

[web-servers]
local

Note: instead of local need to change the actual IP address and it will work for you.

Feel free put your point of view if any. Happy learning and implementation!!!
