Top 10 Free Docker Courses for Java Developers and DevOps Engineers

Knowledge and experience about Docker could be very valuable for your career, especially in 2018. The latest stats and figures show some amazing numbers like jobs requiring these skill sets pay higher than most of the jobs posted on public job boards within the US and annual salaries for professionals could be as high as $100,000.

That is the exact reason why you should you learn Docker in 2018 and take your career to the next level and nothing is better than starting with some free resources.

I have been sharing some free resources, e.g. books and courses, for quite some time and if you are the first time here, you may want to search through the box to find out about free online courses on Java, Spring, Kotlin, DevOps, Eclipse, Jenkins, Rails, PHP and MySQL, Oracle, Linux, etc.

In this article, I am going to share 10 free Docker courses you can use to learn Docker and Containerization of applications.

As I said, Docker and containers are a whole new way of developing and delivering applications and IT infrastructure and here is my list of some of the free courses Java developers can use to learn Docker.

In this course, you will understand what Docker On Windows is all about and how Docker on Windows is same as Linux Containers.

You will also learn Hyper-V, namespace isolation and server containers in depth.

8. Deploying Containerized Applications Technical Overview

Docker has become the de facto standard for defining and running containers in the Linux operating system. 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.

This is an Official Red Hat course about containers using Docker running on Red Hat Enterprise Linux.

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

9. Docker Deep Dive

As the title suggests this is a great course to learn Docker in depth. It provides a good experience for core Docker technologies, including the Docker Engine, Images, Containers, Registries, Networking, Storage, and more.

You will also learn theory and all concepts are clearly demonstrated on the command line.

And the best part of this course is that no prior knowledge of Docker or Linux is required.

10. Docker and Containers: The Big Picture

In this course, you'll learn how this is going to impact you as an individual as well as the teams and organizations you work for.

This course will cover Docker and containers, container registries, container orchestration, whether this stuff is for the enterprise, and how to prepare yourself for it.

These two courses from Pluralsight are not really a free; you need a Pluarlsight membership to get this course, and monthly membership costs around $29 and annual membership cost around $299.  

I know, we all love free stuff, but you will not only get access to this course, but over 5000 courses as well, so it's definitely the money well spent. 

I have an annual membership because I have to learn a lot of new stuff all the times. Even if you are not a member, you can get this course for free by signing a free trial. Pluralsight provides 10-day free trial with no obligation.

That's all about some of the free Docker container courses for Java developers. It's one of the essential skill if you are developing a mobile application or web application hence, I suggest every application developer learn Docker in 2018. You will not only learn an essential skill but also take your career to next level, given high demand of Docker specialist and developer who knows Docker.
