One of the significant advancements in recent times is the container technology. As an IT professional, if you have worked with Docker, then you must know about the role of Kubernetes. Kubernetes certifications can help you find new opportunities for your career in application development. Since the integration of all Docker operations with Kubernetes in 2017, the latter has gained substantial popularity. 

Kubernetes is an open-source system for container orchestration, thereby helping users derive the maximum possible value from containers. It also helps in the automatic management of networks alongside the creation of logos and alerts as well as the deployment of container technology in IT operations. Kubernetes has been under the management of the Cloud Native Computing Foundation (CNCF), which takes care of the implementation and deployment of Kubernetes. 

The CNCF is the governing authority for the two Kubernetes certifications, which help in improving your knowledge regarding Kubernetes. The dominance of Kubernetes in the world of DevOps is one of the reasons to choose to go for certifications in Kubernetes. The following discussion would reflect on the important details regarding certifications related to the Kubernetes platform.
