How have containerization technologies impacted operating system design in modern computing?

Over the past decade, containerization technologies like Docker and Kubernetes have revolutionized how applications are deployed, managed, and scaled. Traditionally, operating systems were designed to manage hardware resources, provide services, and run applications within their environment. However, with the advent of containerization, the role of an OS has evolved, focusing more on providing a minimal and efficient platform to support container workloads. This shift has also led to the development of specialized operating systems optimized for containers, such as CoreOS and RancherOS. How do these changes affect the traditional architecture and functionality of operating systems, and what does this mean for future OS development?
