In this article, I will take you through the steps to install docker on CentOS 7.
Docker is an open source software platform to create, deploy and manage virtualized application containers on a common operating system (OS), with an ecosystem of allied tools.
Docker Inc., the company that originally developed Docker, supports a commercial edition and is the principal sponsor of the open source tool.
Install Docker
Here are the simple steps to install docker in CentOS 7.
Prerequisites
Before trying to install Docker from binaries, make sure your machine meets the following prerequisites:-
a)A 64-bit installation
b)Version 3.10 or higher of the Linux kernel. The latest version of the kernel available for your platform is c)recommended.
d)iptables version 1.4 or higher
e)git version 1.7 or higher
f)A ps executable, usually provided by procps or a similar package.
g)XZ Utils 4.9 or higher
Upgrade packages through yum tool
First, we need to update our system using yum update command.
[root@localhost ~]# yum update
Loaded plugins: fastestmirror
Determining fastest mirrors
* base: mirrors.piconets.webwerks.in
* extras: mirrors.piconets.webwerks.in
* updates: mirrors.piconets.webwerks.in
base | 3.6 kB 00:00
extras | 2.9 kB 00:00
updates | 2.9 kB 00:00
No packages marked for update
Install Docker from yum repository
Now, we can directly install the docker package using yum install docker command.
[root@localhost ~]# yum install docker
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.piconets.webwerks.in
* extras: mirrors.piconets.webwerks.in
* updates: mirrors.piconets.webwerks.in

Check from the rpm database if docker is installed or not
Once installation completed, Check if it is installed or not using rpm command.
[root@localhost ~]# rpm -qa | grep -i docker
