Top 5 Free Courses to Learn Jenkins, Docker, and Kubernetes in 2020 - Best of Lot

Hello guys, you might have heard about DevOps and all the attention it is getting now. The DevOps is a new phenomenon, and there is a mad race among senior developers to become a DevOps engineer. Well, I am not one of them as my passion is for becoming a software architect, but I have indeed spent some time learning DevOps just to increase my knowledge of the field as I strongly believe in the phrase, jack of all and master of one :-). In DevOps world, tools matters a lot, and the whole of the DevOps phenomenon to create an automated pipeline for delivering quality software heavily relies on cleaver uses of tools like Maven, Jenkins, Docker, Kubernetes, and others.

If you are learning DevOps for one reason or other and looking for some excellent courses to kick-start your journey, then you have come to the right place. In this article, I am going to share some of the best DevOps courses which are also free and covers essential tools like MavenJenkinsDocker, and  Kubernetes, which every DevOps Engineer should know.

These courses are definitely not in-depth but will provide you enough knowledge to start and work in your project and also to explore more, which is very important for beginners.

Also, don't think that because these are free courses, they are of poor quality. Most of these courses are presented by the experienced instructor which are expert in the DevOps field and knows what they are talking.

These courses are just made free of marketing and educational reasons. Most of the time, the Instructor also coverts their free course to paid one once they reach their promotional target, particularly in Udemy. o please be aware of that and check the price before you join the class.

Btw, if you are just looking for one course which covers basic DevOps and most of these tools, then I suggest you join Master in DevOps: Docker Jenkins GIT CI Pipeline and Maven course in Udemy. This is not free, but you can get it within just $10 in many flash sales of Udemy, and its well worthy of your time.

5 Free Courses to Learn Maven, Jenkins, Docker, and Kubernetes for DevOps

There are a lot of free courses, books, and tutorials available on the internet, but I have chosen only 10 of them and that too to learn different tools from a DevOps perspective.

These courses will teach you to build tools like Maven, CI/CD tools like Jenkins, Containers like Docker and Container management technology like Kubernetes, and build too like Apache Maven or Gradle. Once you learn these tools, you should be able to more comfortable working as a DevOps professional. You should also be able to implement DevOps in your project.

Without any further ado, here is my list of some of the free courses to learn essential DevOps tools like Maven, Jenkins, Docker, and Kubernetes.

1. Build+Deploy+Test with Jenkins 2.0

There is no doubt that Jenkins is an integral part of the DevOps toolchain. It is probably the most essential tool, and it exists much before the DevOps phenomenon started.

Some people actually credit Jenkins for starting DevOps because it was this tool that first introduced automated build and deployment for Java projects. Anyway, talking about this course, it's a fantastic course to build, deploy, and testing with Jenkins 2.0.

The course is free, and it has 4.3 ratings on average on Udemy from more than 33K students, which speaks a lot about its quality.

Instructor Karthik KK is both enthusiastic as well very clear. The lessons are also fast-paced but well explained and to the point, which means you will learn a lot in a quick time. I learned a lot.

If you don't like a fast-paced course, you can also slow down the speed to go as per your convenience. In short, it is the fastest, most engaging, and most explicit free course about Jenkins.

2. Containers 101

Containers like Docker are again an essential part of DevOps, as it allows them to scale quickly, set up a new environment with a click of buttons, and abstract the Harward part from an application. Good knowledge of containers is essential for DevOps professionals, and that's where this course helps.

Again, the course is free, at least at the time of this writing, and got on average 4.3 ratings from more than 7.5K students.

In this course, you will learn about how to build and deploy applications to modern container platforms with Kubernetes, Docker, and Helm. It contains more than 6 hours of content, so it's no mean a short course.

Actually, it's a collection of recorded webinars, but the content is excellent and gives a good overview of Docker and DockerCopose. Notably, the best practices and implementation tips are fantastic.

3. Maven Quick Start: A Fast Introduction to Maven by Example

Some people may argue that Gradle is a better tool than Maven, and that may be true, but we can't ignore Maven's importance and presence in the current software development world.

It's without a doubt the most common build tool and dependency management system, and most of the companies and startups use Maven for building their project, and that's what makes it essential for DevOps engineers.

Talking about the course, it's a free course with 3 hours of content. It has got, on average, 4.4 ratings from almost 20K students who are quite impressive.

The course provides a step by step guide to learn Apache Maven. You will learn about core concepts, how to use Maven with Eclipse, build Java projects using Maven, Integrate Git source control with Maven, and find and manage dependencies in Maven.

In short, a perfect course to learn Maven for Java developers and DevOps engineers.

4. Getting Started with Google Kubernetes Engine 

Along with Docker, Kubernetes is another awesome and essential tools for DevOps engineers. Almost all microservice-based applications are now using Kubernetes for scaling, and that's why you need to understand and master Kubernetes.

The course will teach you how to deploy, manage, and scale dockerized apps in Kubernetes, a fantastic product from Google, which helps deploy software or web applications, scaling, and management of containerized applications. It also touches based on the deployment in the cloud using Google Cloud.

Talking about course, this is a free course on Coursera, offered by Google Cloud and provides 6hours of content. It has amassed 4.5 ratings around 30,000 students, which is very impressive. Btw, like many other free Coursera courses, it won't provide you any certification.

If you want a certificate, then you need to purchase the course, which will then also give you access to many quizzes, assessments, and peer reviews. You can even show that certificate in your LinkedIn profile, which can also attract a lot of recruiters looking for these cutting edge skills.

By the way, if you find Coursera courses useful, then I also suggest you join the Coursera Plus, a subscription plan from Coursera which gives you unlimited access to their most popular courses, specialization, professional certificate, and guided projects. It cost around $399/year but its complete worth of your money as you get unlimited certificates

5. Getting Started With Docker: Key Concepts for Beginners

Along with Jenkins, Docker is probably the most essential tool for DevOps engineers. It's also the most popular container available to deploy your microservices.

Talking about the course, it's again a fantastic course from Linux Academy and contains around 2 hours of content, which may sound less, but it's packed with a lot of information.

The course is free and has, on average, 4.4 ratings from 25,000 students, which is very impressive. The instructor is also an expert and very clear and confident.

The course is also very hands-on, and you will immediately start using Docker if you follow along. You will first learn how to install and configure Docker and then move to more advanced topics like building custom images using Dockerfile, managing images and containers and understanding container life-cycle, etc.

In short, an excellent free course to start with Docker, the very container one is using.

That's all about some of the best courses to learn DevOps and some of the essential tools like Jenkins, Maven, Docker, and Kubernetes for DevOps developers. As I have said, DevOps is a new phenomenon, but DevOps engineer is very high in demand, and if you want to give your career a boost, you should spend some time learning DevOps and enhancing your profile.
