Top 5 Free Docker Courses for Beginners to Learn Online in 2022 – Best of Lot

Long ago, when there were no containers, everything which needs to be transported is individually loaded into the ship, but that makes the loading and unloading of goods difficult.

Then shipping companies came up with the idea of a container of different sizes, which can be quickly loaded or unloaded using cranes. This helps them to transport goods more efficiently.

Docker works in the same concept, but instead of goods, it carries software. If you know that software is not a monolithic piece but a collection of many different technologies, like database, web server, application server, configuration files, shell scripts, etc.

It’s not easy to set up a complex real-world Java application because you need many different things; Docker solves this problem by putting everything you need into a container and deploying wherever you want, like on Linux, Mac, or Windows.

This seriously helps all the DevOps guys who are trying to automate and simplify every step of software development. So, if you want to improve your productivity or want to move into the DevOps space, good knowledge of Docker is essential.

If you are a Java developer and can spend few bucks like $9.99, then Docker for Java Developers is a great course to start with. It’s written primarily for Java developers.

5 Best Free Courses to Learn Docker Online in 2022

In this article, I’ll share 5 free courses to learn Docker and Containerization online. These courses will teach you Docker, from scratch, right from the beginning of containerization and the benefit of deploying your application in a container, and how Docker helps achieve that.

In these courses, you will learn what a Docker is, how it works, and what benefits it provides. You will also learn how to automate your software development and deployment process using Docker and other automation tools like Selenium.

Some of the courses also explain Docker in depth by discussing Advanced Docker concepts and tools, which can help you both web developers and DevOps engineers like how you set up a development environment with Docker quickly for a new developer or someone like designers, BAs and QAs. You can use Docker images to run the whole of your application on their machine.

1. Docker Course Made for Developers 

This is one of the best courses to learn Docker, particularly for developers. It doesn’t matter whether you are a Java or Web developer; you will learn a lot about Docker in this course.

4. Understanding Docker and using it for Selenium automation [Free]

This is a little bit a different kind of course on Docker. The course is focused on testing automation using Docker.

In this course, you will learn about Docker, like what a Docker is and how to set up a Docker instance in your local environment, and how you can integrate Selenium with Docker for automation testing.

This course is divided into three parts.
1. Understanding the Docker Fundamentals
2. Docker Compose
3. Selenium Grid with Docker

All three parts are intrinsic, meaning they are interdependent on each other, and hence, sometimes, you may need to go back and forth to get into some related concepts.

The first two parts deal with Docker and its related commands. In contrast, in the third section, one much has knowledge on Selenium with C# to write code on the visual studio for running tests in parallel on multiple containers and multiple browsers.

Overall a great course to learn Docker basics for Developers and Testers. Even DevOps can benefit from this course because it talks about infrastructure and Automation.

5. Deploying Containerized Applications Technical Overview [Free Course]

This is an official Docker training course from Red Hat. In this course, Jim Rigsbee, a curriculum architect for Red Hat Training, will introduce you to container technology using Docker running on Red Hat Enterprise Linux.

In this course, you will learn container technology and deploy a single three-tiered Java EE application using several container-based platforms, including Docker, Kubernetes, and OpenShift Enterprise by Red Hat.

Docker has become the de facto standard for defining and running containers in the Linux operating system in the last couple of years, while Kubernetes is Red Hat’s choice for container orchestration. OpenShift, built upon Docker, Kubernetes, and other open-source software projects, provides Platform-as-a-Service (PaaS) for the ultimate in deploying applications within containers.

In short, an excellent course for System administrators, application software developers, and anyone who wants the necessary foundations on Docker, Kubernetes, OpenShift, and Platform-as-a-Service capabilities.
