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 />

<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="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 />
