What is Kubernetes? Official definition would look like this:
Kubernetes is an open-source platform designed to automate the deployment, scaling, and operation of containerized applications. It allows you to manage clusters of hosts running containers, providing mechanisms for deployment, maintenance, and scaling of applications. Kubernetes is widely used for its ability to simplify the management of complex applications by automating many of the processes involved in running containers, such as load balancing, scheduling, and resource management.
