Kubernetes is an open-source container orchestration tool for automating the deployment, scaling, and management of containerized applications. It has become the de facto standard for container orchestration and microservices deployment and it is one of the sought-after DevOps skills in the current IT market.
The CKA program offers a robust curriculum that covers all aspects of Kubernetes administration, from installation and configuration to networking and security. Candidates who successfully complete the CKA exam will earn a globally recognized credential that demonstrates their skills and knowledge in Kubernetes.
If you're looking to start a career in DevOps, or simply want to deepen your understanding of Kubernetes, the CKA certification is a great place to start. Also, it is one of the most in-demand devops certifications.
The following table has the important CKA certification details.
CKAD is a Kubernetes certification that focuses on designing, building, and deploying cloud-native applications for Kubernetes. If you have CKA certification, passing CKAD is comparatively easier. It is a two-hour performance-based exam, and the following are the CKAD certification details.
CKS certification focuses on security best practices of Kubernetes application deployments. The certification topics are organized in a way that you learn all the concepts and tools around container security on Kubernetes.
You must also have a valid CKA certification to appear for CKS. Like CKA and CKAD, it is a two-hour performance-based exam. However, CKS is comparatively tougher, so you need to practice well before the exam.
Note: You can also start with KCSA certification. It is a introductory kubernetes security certification.

My first certification as a Devops engineer was AWS-certified solution architect because I was primarily working on AWS cloud-related projects. It makes more sense to start with a certification on the technologies you are working with.
For example, if you are a Linux admin and want to become a DevOps engineer, you can get certified in Kubernetes as it is more relevant to the domain you are already in. That is "System Administration".
Here is my advice on devops certification.
Start with one Certification that is closely related to your existing domain. If you are completely new to DevOps, the following DevOps certification roadmap would help.
