Using Vagrant, developers and sysadmins can create any virtual environment instantly. Vagrant is extremely simple to use and configure.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Vagrant acts as central configuration repository for managing and deploying multiple reproducible virtual environments from a canned OS image with same configuration.<br />
<span id="more-16756" style="margin: 0px; padding: 0px; word-wrap: break-word;"></span></div>
<h3 style="background-color: white; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 1.286em; font-weight: normal; line-height: 1.222em; margin: 1.833em 0px 0.611em; padding: 0px; word-wrap: break-word;">
<span style="color: #0b5394;">1. Install Vagrant</span></h3>

Please note that vagrant is available on windows as well which means you can download and install vagrant and virtualbox on your windows machine and then run the vagrant commands to quickly build any available vagrant OS’es for your testing.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Install the downloaded file on your system using your systems appropriate package installer. Since i am installing this on CentOS.</div>

<span style="color: #0b5394; font-size: large;">2. Add a Vagrant Box</span></h3>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
The next step is to run “vagrant box add” command. In this example, I am using one of the predefined catalogs available on HashiCorp’s Atlas box catalog. This catalog has <a href="http://www.hackthesec.co.in/2016/01/how-to-install-linux-apache-mysql-and.html" target="_blank">LAMP </a>stack already configured on it.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: white;"># vagrant box add smallhadroncollider/centos-6.4-lamp

</span><span style="color: lime;">==> box: Successfully added box 'smallhadroncollider/centos-6.4-lamp' (v1.1) for 'virtualbox' !</span></span></span></pre>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Verify that the vagrant box is successfully added using the following command. This will display all the vagrant boxes that are installed on our system. Currently we have only one box installed.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: white;"># vagrant box list

<span style="color: #0b5394; font-size: large;">3. Initialize Vagrant Box</span></h3>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Now we are ready to initialize the new Vagrant environment by creating a vagrant file. vagrant status command displays the currently initialized vagrant environments. In this case since we do not have any machines initialized yet, vagrant status gives the below output.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: lime;"># vagrant status

</span><span style="color: white;">A Vagrant environment or target machine is required to run this
command. Run `vagrant init` to create a new Vagrant environment. Or,
get an ID of a target machine from `vagrant global-status` to run
this command on. A final option is to change to a directory with a
Vagrantfile and to try again.</span></span></span></pre>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Now we can create a new directory and initialize the vagrant environment that we just downloaded, this will place a plain vagrantfile in the current working directory. You can change many of settings in this file, we can change things such as network configuration, shared folders, and puppet and chef details.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Just be aware a box restart will likely be required before changes take effect.</div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
To learn more about configuration inside the vagrant file, you can refer the<a href="https://docs.vagrantup.com/v2/vagrantfile/version.html" style="color: #dd0000; margin: 0px; padding: 0px; word-wrap: break-word;">vagrant documentation</a>.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: lime;"># mkdir centos-6.4-lamp
</span><span style="color: white;">
# cd centos-6.4-lamp

# vagrant init smallhadroncollider/centos-6.4-lamp
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
</span><span style="color: lime;">`vagrantup.com` for more information on using Vagrant.</span></span></span></pre>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
After you initialize vagrant box, you’ll see that it has created the following file under the current directory.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: white;"># ls -ltr
</span><span style="color: lime;">-rw-r--r--. 1 root root 3017 Jan 27 18:29 Vagrantfile</span></span></span></pre>
<h3 style="background-color: white; font-family: Georgia, 'Times New Roman', Times, serif; font-weight: normal; line-height: 1.222em; margin: 1.833em 0px 0.611em; padding: 0px; word-wrap: break-word;">
<span style="color: #0b5394; font-size: large;">4. Provider Dependency</span></h3>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Now if you to try to bring up the vagrant machine, you will see the below error. This is because the provider has not been installed yet on the machine. The provider can be usually Oracle Virtualbox, VMWARE, Hyper-V. Once you choose the provider, depending on OS platform install the respective rpm on the machine.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: white;"># vagrant up

No usable default provider could be found for your system.
Vagrant relies on interactions with 3rd party systems, known as
"providers", to provide Vagrant with resources to run development
</span><span style="color: lime;">environments. Examples are VirtualBox, VMware, Hyper-V.
The easiest solution to this message is to install VirtualBox, which
</span><span style="color: white;">is available for free on all major platforms.

If you believe you already have a provider available, make sure it
is properly installed and configured. You can see more details about
why a particular provider isn't working by forcing usage with
</span><span style="color: lime;">`vagrant up --provider=PROVIDER`, which should give you a more specific
</span><span style="color: white;">error message for that particular provider.</span></span></span></pre>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Note: In my case, I have downloaded and installed Oracle Virtualbox. You need to have one of the virtualization provider installed on your machine for this to work. </div>
<div style="background-color: white; color: #111111; font-family: Georgia, 'Times New Roman', Times, serif; font-size: 16px; line-height: 26px; margin-bottom: 26px; padding: 0px; word-wrap: break-word;">
Once a provider (Oracle virtualbox, VMWare, etc.) is installed, try to bring up the virtual environment using “vagrant up” as shown below, you can also setup your public network and any other software packages needs to be included or any other configurations in the vagrant file and bring up the virtual machine.</div>
<pre style="background: none 0px 0px repeat scroll rgb(60, 60, 60); border-radius: 4px; border: 1px solid rgb(229, 229, 229); margin-bottom: 20px; outline: 0px; overflow: auto; padding: 20px; vertical-align: baseline;"><span style="font-size: medium;"><span style="line-height: 15.6px;"><span style="color: white;"># </span><span style="color: lime;">vagrant up</span><span style="color: white;">
Bringing machine 'default' up with '</span><span style="color: lime;">virtualbox</span><span style="color: white;">' provider...
==> default: Importing base box 'smallhadroncollider/centos-6.4-lamp'...

How to install Docker on CentOS 7 / RHEL 7

<div dir="ltr" style="text-align: left;" trbidi="on">
<span style="color: red; font-size: x-large;"><u><i>Install Docker on CentOS 7/RHEL7</i></u></span><br />
Docker is an <b>open-source tool that makes creating</b> & <b>managing Linux containers</b>(LXC) easy. Containers are like lightweight <b>VMs which can be started</b> & stopped in milliseconds. Dockers help the system admin & coders to develop their application in a container and can further scale up to 1000 of nodes.<br />
<br />
The main difference between container and <b>VM</b>(<b>Virtual machine</b>) is that dockers provide process based isolation , whereas VM provides full isolation of resources. Virtual machine takes a minute to start where as container can be started in a second or less than a second. Container uses the Kernel of host OS , whereas <b>VM</b> uses the separate Kernel.<br />

<br />
<br />
One of the limitation of <b>Docker</b> is that it can be used only on<b> 64bit hosts OS</b>.<br />
<br />
<br />
<span style="color: #073763; font-size: large;">Installation of Docker on CentOS 7</span><br />
<br />
Docker package is included in the default <a href="http://www.hackthesec.co.in/search/label/Centos">CentOS</a>-Extras repository. So to install docker , simply run below yum command :<br />
<br />
<span style="background-color: black;">[<span style="color: white;">root@localhost ~]# yum install docker</span></span><br />
<br />
<span style="color: #0b5394; font-size: large;"><u>Start the Docker Service</u></span><br />
<br />
Once the Installation is finished , start docker service and enable it at boot using below commands<br />
<span style="background-color: black;"><br /></span>
<span style="background-color: black;"><span style="color: white;">[root@localhost ~]# service docker start</span></span><br />
<span style="background-color: black;"><span style="color: white;">[root@localhost ~]# chkconfig docker on</span></span><br />
<span style="background-color: black; color: white;"><br /></span>

<u><b>Run a Docker Container :</b></u><br />
<u><br /></u>
<span style="color: #cc0000;">[root@localhost ~]# <b>docker run -i -t centos /bin/bash</b></span><br />
<br />
<span style="color: #cc0000;">[root@dbf66395436d /]#</span><br />
<span style="color: #990000;"><br /></span>
As we can see centos container has been started and we got the bash shell. In docker command we have used options like ‘-i attaches stdin and stdout’ and ‘-t allocates a terminal or console’ . To disconnect from container type exit .<br />
<br />
<span style="color: red;">[root@cd05639b3f5c /]# <b>cat /etc/</b></span><span style="color: #351c75;"><b>redhat-release</b> </span><br />
