Best Resources to learn Docker and Kubernetes – 2021

This is the era of cloud and almost every company is adopting the cloud-native approach and we can see a rise in interest for cloud computing, containerization and orchestration solutions. When we talk about cloud-native approach, it is impossible to ignore the tools name like Docker and Kubernetes, which have revolutionized the way we create, develop, deploy and ship software at scale.

What is Docker?

Before knowing what is Docker? – Let’s see what were the problems before Docker existed? Earlier the developers used to send the code to the testers, but sometimes due to various dependencies the code could not run on the tester machines, but it worked fine on the developer’s machines.

Docker removed that issue called “dependencies”. It makes it extremely easy for teams to run applications in similar environment without any issues of dependencies or OS as it provides its own OS libraries. The Development team and the testing team now have the same system running on Docker containers. It allows to “Build, Ship, and Run applications, Anywhere.” If it works on your machine, it will work on others’ machines. It packages up the services comprising an application and make them portable across different compute environments, for both devopers, testers and production uses.

While Docker provides open standard for packaging and distributing containerized applications, there are problems which needs to be tackle down.

  1. How containers can be coordinated and scheduled?
  2. How to seamlessly upgrade an application without interrupting the services?
  3. How to monitor the health of the application and know when something goes wrong and seamlessly restart it?

What is Kubernetes?

Then, the solution comes as a Container Orchestration tool called – Kubernetes. It can handle the container management responsibilities like container deployment, scaling, healing, and load balancing of containers. Docker helps us to create containers, and Kubernetes allows us to manage them at runtime.

Docker and Kubernetes adoption is increasing day by day in the modern cloud architecture. Using both of the tools has become a modern standard and new norm of the industry for faster application deployments and releases.

Big tech giants like Google, Microsoft, IBM, Amazon, Red Hat offer managed Kubernetes under the containers as a service (CaaS) or platform as a service (PaaS) model. Many companies globally are using Kubernetes in production on a massive scale – already. Millions of professionals and teams are dependent on Docker and Kuberentes these days, and more than fortune 500 companies have adopted Docker and Kubernetes globally. In the coming years Docker and Kubernetes are not going anywhere. All in all, Docker and Kubernetes are those trending technologies which can boost your career in the years to come. So, if you are someone who really want to have a dynamic job with a big salary, then add Docker and Kubernetes to your portfolio.

So, now the question is How to start learning Docker and Kubernetes? & What are the best resources to learn Docker and Kubernetes??

There are many self-learning options are available – I have tried here you to consolidate few of them:-

Docker and Kubernetes best resources to learn (Paid):-

Now, when it comes to learn faster, nothing can beats the personal training. “IT” is one of the most challanging career where things use to change frequently and co-op with new technologies is really challenging, it demands professionals to always aquire new knowledge time to time, so that they can remain valued as per the industry requirement. In this we can not always rely on self-learning where we need more time to find the contents, try the things, get the errors and learn. If any one wants to save their time energy to learn new things then hand holding and taking guidance from experts are the best option and for that their are several online courses available.

Here I can suggest two courses – these courses are the best way to get trained and certified in Docker and Kubernetes for an Absolute Beginner.

Docker Certified Associate (DCA)

Certified Kubernetes Administrator (CKA)

These courses are precisely intended for the participants who want to learn and claim their Docker certification and Kubernetes certification as well as for those aspirants who want to have the expertise on Docker and Kubernetes concepts. This course is suitable for any participant and designed in a way where it doesn’t matter your previous experience which makes it a go-to course for any individual who are new to the field of Containerization.
