Docker Tutorial

Last Updated : 28 May, 2025

Docker is a tool that simplifies the process of developing, packaging, and deploying applications. By using containers, Docker allows you to create lightweight, self-contained environments that run consistently on any system, minimising the time between writing code and deploying it into production.

In this tutorial, we will guide you through Docker from scratch. You’ll understand Docker’s key features, how it works, and how to perform important tasks such as installing Docker, running containers, managing images, and handling other essential Docker operations used in development and deployment.

Docker Introduction

Let us start with an introduction to help you understand what Docker is and why it's widely used across the globe. Next, we’ll cover the key features of Docker and how it benefits application development and deployment. Finally, we’ll explain Docker Architecture to give you a clear understanding of how Docker works.

After giving you this basics clarity we will move on to central registry Docker Hub for sharing and managing containers and at last of this section we will introduce Docker Cloud where you will learn about the utilization of docker in the cloud environment.

Docker Installation

This section will walk you through the steps of installing Docker on your system, whether it's Windows, macOS, or Linux. We'll cover the different installation methods, system requirements, and post-installation configurations to ensure you have Docker up and running smoothly, ready to build and run your containerized application

Docker Commands

When you want to build, run, or manage containers, you use Docker commands. These commands make it easy to control your Docker applications and get things done quickly. This section will teach you the key Docker commands you need to work with containers.

Docker Run and Dockerfile

docker run is the command used in Docker to create and start containers based on Docker images. It's a fundamental aspect of working with Docker, allowing users to deploy applications and services quickly and efficiently within isolated environments known as containers. Here in this section, you will get to know all the details about the Docker Run.

Docker Images

A Docker Image contains everything a container needs to run, including the application code, libraries, dependencies, and the operating system it needs, Here is all you need to know about Docker images:

Docker Compose

When working with several containers at once, things can get complicated. Docker Compose makes managing these multi-container applications simple and efficient. Here, you’ll learn about Docker Compose and the key tools that make container management easier.

Docker Engine and Storage

Docker Engine, also known as Docker Daemon, is the core component of the Docker platform responsible for running and managing Docker containers. Explore this section to get all details about Docker Engine:

Docker Networking

Docker Networking refers to the set of mechanisms and technologies Docker provides for communication between Docker containers, as well as between containers and the outside world. Go through this section to get more details about Docker Networking:

Docker Registry

After learning the Docker Networking, in this Docker tutorial, we are going to discuss Docker Registry which is refer as central repository for storing the and managing Docker image.

Docker Containers and Managing Containers

Explores this section to get to know about the fundamental concepts and practical aspects of utilizing Docker technology to deploy and manage software applications efficiently in this section:

Docker Swarm

Docker Swarm steps in as your reliable organizer, making sure all your containers are in the right place and working well together. Go through this section to get an all about Docker Swarm.

Miscellaneous

In this section we are going to know about the miscellaneous topics of docker which are important and very easy to learn:

Advantages of Using Docker

Docker containers are widely used by developers for building, testing and shipping applications faster across any platform. Apart from this there are so many other benefits provided by Docker. The following are the advantages of docker:

Your application will work same on any system whether you are using any laptop, server or any cloud (AWS, GCP, Azure).
In docker each application will run on it's own space, so it won't hamper another application work.
Docker containers start quickly, so your app runs in no time.
You can test new features without changing your main application
Docker uses less memory and power than virtual machines
You can easily add more containers if more people use your application.
Docker works well into development tools and automation setup.

Conclusion

Docker is a software development framework that allows you to package and run apps inside virtual machines on a server. It's often used to create and test applications before deploying them on a real, physical server. This allows organizations to test and deploy their applications quickly and with minimal resources. Docker also makes it easy to package and update apps on any server, regardless of its hardware configuration.
