In web hosting, deploying applications efficiently has become a pivotal challenge for businesses seeking optimal performance. As the digital realm expands, the demand for scalable and portable solutions has given rise to containerization technologies. Docker, a leading player in this arena, empowers developers to encapsulate applications and their dependencies into lightweight, portable containers. The containerization market on a global scale is anticipated to experience significant growth in the upcoming years. Thus highlighting the growing acceptance of containerized solutions across various industries.

How do you leverage the capabilities of Docker containers, especially in the context of Virtual Private Server (VPS) hosting in India? Keep reading to discover the solution.

What is Docker and How Does it Work?

Docker is a containerization platform, transforming application development, shipping, and deployment. It empowers developers to package an application and its dependencies into a compact, easily transportable container. These containers are isolated environments that guarantee consistent performance across different computing environments.

Docker employs a client-server architecture where the client communicates with the Docker daemon. The daemon, in turn, manages container creation, running, and other essential tasks. Containers share the host OS kernel but run in isolated user spaces, ensuring efficient resource utilization and rapid deployment.

The power of Docker is evident in its capability to package applications with their dependencies, facilitating seamless transfer across diverse systems. It eradicates the longstanding “it works on my machine” issue and simplifies the development-to-deployment process. Docker transforms applications into portable, scalable, and easily maintainable entities. Thus, it marks a significant advancement in the efficiency of software development and deployment practices.

What Are the System Requirements for Installing Docker?

Docker functions seamlessly with Windows, diverse Linux distributions, and macOS. Given the unique environments of these platforms, each has its own system requirements before being deployed in VPS hosting in India. Here’s a breakdown for each OS

Windows

Before you deploy Docker on VPS hosting in India on Windows system, ensure

• A 64-bit CPU with Second Level Address Translation
• 4GB of RAM
• Hardware virtualization enabled in the BIOS settings
• For Docker with Windows Subsystem for Linux 2 (WSL2), Windows 10 64-bit Home, Pro, Enterprise, or Education (version 1903 or higher) is required, with the WSL 2 feature enabled and the Linux kernel update package installed.
• For those using Hyper-V’s backend and Windows containers, Windows 10 64-bit Pro, Enterprise, or Education (Build 17134 or higher) with Hyper-V and Containers feature enabled is necessary.

Linux

Before you deploy Docker on VPS hosting in India on Linux system, ensure

• Docker seamlessly supports diverse CPU architectures on Linux, guaranteeing compatibility with well-known distributions like CentOS, Debian, Fedora, Raspbian, and Ubuntu. 
• To achieve peak performance, Linux users are recommended to have a minimum of 2GB of RAM, with a requirement of at least 512MB.
• The system mandates a kernel version of 3.10 or newer. 
• Storage space and CPU power requirements are influenced by factors like the number of containers and the characteristics of stored applications.

macOS

Before you deploy Docker on VPS hosting in India on Linux system, ensure

• For Mac computers equipped with an Intel chip, ensure macOS version 10.14 or newer is installed, with a minimum of 4GB RAM. 
• Avoid compatibility issues by not having VirtualBox versions older than 4.3.30 installed. 
• For Mac machines with Apple CPUs, make sure Rosetta 2 is installed.

How to install Docker in VPS?

Setting up Docker on your VPS hosting in India is easy. Follow these straightforward steps:

Step-1: Access VPS

Access your VPS hosting in India using admin privileges. If you’re logged in as the primary administrator, you can omit the “sudo” prefix in the following commands.

Step 2:Update System

Next, make sure your system is up-to-date by running the command: sudo yum update -y

Step 3: Configure Docker

As Docker isn’t part of the standard software repository, you’ll have to configure it yourself. Begin by installing the yum-utils package: sudo yum install yum-utils -y

Step 4: Add Docker Repository

Then, add the Docker repository:

sudo yum-config-manager –add-repo https://download.docker.com/linux/centos/docker-ce.repo

Step 5:Install Docker and Containered

Now that the repository is set up, let’s proceed to install Docker and Containerd.

sudo yum install docker-ce docker-ce-cli containerd.io

Step 6: Activate Docker

Activate Docker on your VPS:

sudo systemctl start docker

Step 7: Test

To ensure everything is running smoothly, run a quick test:

sudo docker run hello-world

That’s it! Your VPS is now equipped with a fully operational Docker setup, allowing you to effortlessly deploy and oversee containers.
