<\/a>1. What is Docker?<\/h2>\nDocker<\/a> is a platform used to develop, deploy, and run<\/strong> applications by using containers. Docker consists of:<\/p>\n\n- Docker Engine<\/strong> \u2013 lightweight and powerful open source containerization technology combined with a workflow for building and containerizing your applications.<\/li>\n
- Docker Hub<\/strong> \u2013 SaaS (Software as a Service) service for sharing and managing your application stacks.<\/li>\n<\/ul>\n
<\/a>2. What is CentOS?<\/h2>\nCentOS<\/a> stands for Community Enterprise Operating System. It is an open-source Linux distribution that provides a free, enterprise-class, community-supported computing platform functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). The latest Version of CentOS now is 7.0. It is widely used by the System Administrators, DevOps Engineers, and Software Professionals. It is also used by many organizations for the Development and Production Servers.<\/p>\n<\/a>3. Steps for Installation of Docker on CentOS<\/h2>\nTo complete the Installation of Docker on CentOS, It involves two steps:<\/p>\n
\n- Install CentOS<\/li>\n
- Install Docker on CentOS<\/li>\n<\/ol>\n
<\/a>4. Installation of CentOS<\/h2>\nI am using my laptop containing Microsoft Windows 10 Pro Operating System for explaining “Docker Install on CentOS Example”<\/p>\n
How to install CentOS on a machine containing Microsoft Windows 10 Pro Operating System and Version: 10.0.17763?<\/strong><\/p>\nTo accomplish this task, Understand the concept of Virtual Machine.<\/p>\n
<\/a>4.1 What is a Virtual Machine?<\/h3>\nA Virtual Machine (VM) is a software program or operating system that not only exhibits the behavior of a separate computer but is also capable of performing tasks such as running applications and programs like a separate computer. A virtual machine, usually known as a guest (for this example, Virtual machine contains CentOS) is created within another computing environment referred to as a “host” (in my case, the host is Microsoft Windows 10 Pro Operating System). Multiple virtual machines can exist within a single host at one time. Virtual machines are becoming more common with the evolution of virtualization technology. <\/p>\n
Virtual machines are computers whose hardware components are emulated by the host computer. A virtual machine is also known as a guest.<\/p>\n
The following are free Virtual Machine Software available :<\/p>\n
\n- VMware Workstation Player <\/a><\/li>\n
- Oracle VM VirtualBox<\/a><\/li>\n
- Hyper-V (Hyper-V is built into Windows as an optional feature — there is no Hyper-V download.)<\/li>\n<\/ul>\n
I am going to explain this Docker Install on CentOS example<\/strong> by installing Oracle VM VirtualBox<\/strong> on Microsoft Windows 10 Pro and Version: 10.0.17763. <\/p>\n<\/a>4.2 What is Oracle VM Virtual Box?<\/h3>\nOracle VM VirtualBox is a free, open source, cross-platform application for creating, managing and running virtual machines (VMs).
Oracle VirtualBox enables you to set up one or more virtual machines (VMs) on a single physical machine, and use them simultaneously, along with the actual machine. Each virtual machine can execute its own operating system, including versions of Microsoft Windows, Linux, BSD, and MS-DOS.<\/p>\n
VirtualBox runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7, Windows 8, Windows 10), DOS\/Windows 3.x, Linux (2.4, 2.6, 3.x and 4.x), Solaris and OpenSolaris, OS\/2, and OpenBSD. <\/p>\n

I am going to explain this Docker Install on CentOS example<\/strong> by installing Oracle VM VirtualBox<\/strong> on Microsoft Windows 10 Pro and Version: 10.0.17763. <\/p>\n
<\/a>4.2 What is Oracle VM Virtual Box?<\/h3>\n
Oracle VM VirtualBox is a free, open source, cross-platform application for creating, managing and running virtual machines (VMs).
Oracle VirtualBox enables you to set up one or more virtual machines (VMs) on a single physical machine, and use them simultaneously, along with the actual machine. Each virtual machine can execute its own operating system, including versions of Microsoft Windows, Linux, BSD, and MS-DOS.<\/p>\nVirtualBox runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7, Windows 8, Windows 10), DOS\/Windows 3.x, Linux (2.4, 2.6, 3.x and 4.x), Solaris and OpenSolaris, OS\/2, and OpenBSD. <\/p>\n
