How to Install Docker for Windows?

Docker is the most famous containerization platform. Almost all the top companies around the world have digital services that depend on Docker containers for running their applications. Hence, it is very important to understand and learn Docker if you are looking to make a career in the software domain (especially for people in DevOps). This blog discusses Docker and will help you get started with Docker for Windows. The topics covered are as follows:

If you are a beginner, watch this video tutorial to learn Docker from the start:

What are Containers?

Since the era of online software deployments, companies have been looking for easy and effective ways of hosting their software applications. The problem was if you wanted to host multiple instances of your application, you had to have hardware and OS on it to do that. Initially, people depended on normal physical deployments, which were ineffective and expensive. Then, people started using the virtual OS with which they were able to optimize the use of the hardware that was present.

Virtual OS did make the process a bit more effective, but there was still a bit of scope for improvement. The thing many visionaries of the field realized was that an OS is very heavy; it is designed and made in a fashion that users can have as many capabilities as possible. However, for software deployment, you do not need such high-end capabilities. What you need is a set of pretty lightweight libraries. If you were to develop something like this, you would be able to make the entire process extremely efficient and inexpensive and, at the same time, eliminate problems like environmental differences (dependencies installed in systems). You would be able to switch to microservices (segregating your applications into separate stand-alone functionalities, which can interact with each other to produce results). Having this microservice architecture increases the security aspect as well.

With these enormous functionalities, something called a container was born. A container is a software unit that has all code and dependencies. You can run your applications in it, and it is very lightweight as compared to an OS. Now, how did Docker come into the picture?

What is Docker?

Docker is a very popular open-source platform, which helps you create containers and, in turn, helps in creating container-based applications. Initially, when Docker was created, it was made for Linux exclusively, but now, there is Docker for Windows and macOS too. A Docker container is a very simple and lightweight platform that utilizes the resources of your host system to run your application. Docker’s architecture can be seen in the image below.

Docker Terminology

While working with Docker, you will come across some terms quite constantly. Let’s tackle them quickly.


Every Docker container begins with a Dockerfile. A Dockerfile is a text file, which is written in a readable syntax and contains the instructions or steps to build a Docker image. A Dockerfile provides details of the operating system that will be the base of the container, along with the details of languages, environment variables, network ports, file locations, and all of the other required components.

Docker Images

Docker images are templates that are read-only templates created from specifications provided in the dockerfile. Docker images are portable, but they are static. Therefore, you need to be careful with the specifications you are building them with.

Docker Containers

Whenever you run a Docker image, it runs in the form of a Docker container. So, you can think of Docker containers as the runtime instance of a Docker image.

Docker Hub

Docker Hub is the place where you store Docker images. The images stored in Docker Hub can be pulled from a remote server, and those image can be run locally. In Docker Hub, you can have public or private repositories.

Pros & Cons of Docker for Windows

There are certain aspects of why you should use docker for Windows but at the same time, there are some cons to using docker for Windows. Let’s discuss it in detail about it. Let’s begin with the positives first.

Pros of Docker for Windows

1. Security

We live in a digital era where cybersecurity is at the pinnacle of importance. If you use docker for Windows, there is a very high chance that you will be running the “Hyper-V” mode. In this your containers run inside the Hyper-V virtual machine instance which isolates your containers from host servers, hence providing another layer of safety.

2. Solves the different environmental problem

Many software development organizations use both Windows and Linux servers, in that case, using Docker for Windows will help you standardize the toolset that you are using to deploy applications

Now let us talk about some Docker for Windows limitations.

Cons of Docker for Windows

1. Not all Windows versions supported

Docker containers work only on Windows 10 and Windows Server 2016 and later. Microsoft has made no indication that it plans to extend container support to older versions of its operating systems. You may use workarounds in the virtual box and others for the older versions.

2. Issue of dependencies

If you come from a Linux background you would be familiar with a lot of commands like ‘nano’ etc, the problem with Windows is PowerShell and cmd don’t support a lot of these commands but it is nothing that can’t be fixed. You can install a new terminal, and add dependencies to use said libraries the thing is that it’s a hassle. Once you set everything up then it works flawlessly.

Docker for Windows Prerequisites

Prerequisites of Docker for Windows

You need to meet the following requirements for Docker For Windows Installation:

  1. Make sure that you are on Windows 10, either the Enterprise edition or the Pro edition, 64-bit system because Docker is only compatible with Windows 10, and no other editions can be used. However, there is a workaround for older versions of Windows. You can get Docker Toolbox to serve this purpose. This tutorial is going to explain installing Docker for Windows 10.
  2. You would need the hypervisor enabled on your Windows. Hypervisor-V is a lightweight solution for virtualization.
  3. You need to enable virtualization in your BIOS as well.

Now that you are sufficiently informed of the basics of Docker, the blog further takes you through the process of installing Docker for Windows. Follow the steps!
