Why do you need to upskill in Certified Kubernetes Administrator certification?

Learning Kubernetes is no less than mandatory if you want to kick-start your career in DevOps. The CKA exam is one of the hands-on certifications helping you learn Kubernetes the right way by providing a proper curriculum and learning path, being the perfect stepping stone for your career.

Basically, the size and complexity of projects are growing tremendously in the modern IT industry, making it extremely difficult to manage organizational operations. Kubernetes solves this problem with a breeze. It autonomously scales and manages containers used to deploy and test project or application modules.  Moreover, the tool is easy to use, understand, and embed into your current projects.

Also Know: Kubernetes Architecture

Additionally, unlike in monolithic times of IT, where system engineers were responsible for managing virtual machines and virtualization platforms,  Kubernetes takes all the burden for handling such sophisticated container platforms. Organizations are migrating from their legacy virtual machines to containers.

As more organizations become early adopters of this transformation, the demand for engineers specializing in Kubernetes will increase by manifolds, as they will be the only professionals with the expertise to manage their modern application platform.

Long story short, all of this means that in the days to come, you can expect a rapid increase in the hiring of Kubernetes experts. Research says a certified Kubernetes administrator can achieve a salary as high as $215,000 annually.

Pro Tips to prepare for the CKA certification exam

To ace the CKA exam, you need a clear mind and strategy up your sleeves. All you require is hands-on with the recommended skills and well-versed with the exam objectives. Or else it may become complete chaos with an overwhelming syllabus.

So to save you some time, here are a few pro tips and tricks. Include them in your strategy to make your preparations super easy. Let’s have a quick glance.

Step 1: Study the CKA exam guide carefully 

Download the CKA guide and ensure to get a good hold of exam objectives, requirements, and domains. Skim through their learning paths, instructor-led videos, documentation, resources, etc. Map your preparation requirements with the official documents and resources available and decide what additional materials you require to level up your preparations. The CKA exam consists of five domains: 

Domain Weightage
Cluster Deployment, Architecture, and Configuration 25%
Scheduling and workloads  15%
Networking and service  20%
Storage  10%
Troubleshooting 30%


Make sure that you don’t leave any topic or subtopic and focus on every concept. If you haven’t used Kubernetes before, you might find the course trickier and more confusing and would need rigorous practice with the fundamentals. Plan your future phases accordingly. 

Step 2: Prepare a detailed calendar

You might find it tedious and stressful to prepare for such a technical course if you are a professional with a full-time job or a student already preparing for a degree. The best way is to prepare a calendar and create a strategy that captures all the headings and subheadings in the syllabus. This way, you won’t skip any concepts and save time for hands-on and practical sessions. 

Step 3: Develop a comprehensive view of the CKA exam environment

The CKA course includes various mission-critical and technical concepts. So it becomes vital to get acquainted with the exam environment. That’s why we recommend you use the exact techniques and tools while practicing. Getting comfortable with the Kubernetes techniques will help develop speed and fluency to make the exam frictionless.

While dealing with a nuanced syllabus, you may not have the time to read huge manuals and figure out how to use command-line tools while taking the exam. Try to practice your hands-on skills using the following software: 

  • Shell-Bash
  • Editor-Vim
  • Operating system-Ubuntu 18.04
  • Browser-Chrome
  • Command-line tools- kubectl, tmux, jq

Step 4: Read all the documentation carefully

The best part about the CKA exams is that it allows you to use certain websites and documentation to search terminologies and find answers to your questions. Here are a few sites you are allowed to surf for answers:

Developing a working knowledge of these documents can help you develop agility and speed while appearing for the exam. Additionally, these documents will also help you develop a strong foundation in Kubernetes. Try using only sites when searching for concepts and tools and prepare your answers.

Also, learn how to efficiently leverage the search functions in all the K8 docs and bookmark all the relevant and useful pages. 

Step 5: Gain a stronghold of basic Linux Commands

Kubectl will be your main tool for communicating with K8s both during the test and on a daily basis. For the CKA to be successful, kubectl proficiency is essential. You should be able to create, modify, and view objects with it in K8s. Knowing how to configure or fix your present “context” would also be helpful.

Step 6: Start focusing on practical skills

You will spend most of the CKA exam managing K8’s objects and learning about underlying systems in the terminal. Knowledge of the following could therefore be helpful:

  • Vi (to edit files in the terminal therefore, Vim use is critical) 
  • Kubeadm (for upgrading clusters) (for upgrading clusters)
  • Journalctl and Systemctl (for controlling services and viewing logs)
  • Nslookup (to diagnose DNS issues) (to diagnose DNS issues)
  • Curl (to test endpoints) (to test endpoints)
  • Tmux (optional but would permit the use of several

Step 7: Focus on gaining practical exposure
