What is the underlying operating system of Docker?
Introduction:
Docker has emerged as a revolutionary technology that enables developers to create, deploy, and run applications in isolated environments called containers. While Docker itself provides a powerful platform for containerization, its underlying operating system plays a critical role in its functionality and performance. Docker and Kubernetes Training

The Core OS of Docker: Linux
At its core, Docker relies heavily on Linux as its underlying operating system. This dependency stems from several key features inherent to the Linux kernel, which are essential for Docker’s operation:
Namespaces: Linux namespaces provide isolated environments for processes. Docker utilizes namespaces to ensure that each container has its own isolated process tree, network stack, and filesystem, thus enabling multiple containers to run on a single host without interfering with each other.
Control Groups (cgroups): Cgroups are used by Docker to manage and limit the resources (CPU, memory, disk I/O, etc.) allocated to each container. This ensures ...
... that containers run efficiently without monopolizing system resources.
Union Filesystems: Docker uses union filesystems, such as OverlayFS, to manage container images. These filesystems allow Docker to create and manage images efficiently by layering changes on top of a base image, reducing storage usage and speeding up container creation.
Docker and Other Operating Systems:
While Docker was initially developed for Linux, its popularity and the demand for cross-platform compatibility led to the development of Docker Desktop, which allows Docker to run on macOS and Windows. Docker Online Training
This cross-platform functionality is achieved through various approaches:
Docker on macOS and Windows: Docker Desktop for macOS and Windows leverages lightweight virtual machines to run a Linux kernel, ensuring that Docker containers have a consistent Linux environment, regardless of the host OS. On macOS, Docker Desktop uses HyperKit, a lightweight hypervisor, while on Windows, it utilizes the Windows Subsystem for Linux (WSL) 2 or Hyper-V, depending on the version and configuration.

Windows Containers: In addition to running Linux containers on Windows, Docker also supports native Windows containers. These containers use the Windows kernel and are compatible with Windows Server 2016 and later versions. Windows containers rely on technologies similar to Linux, such as namespaces and cgroups, but are implemented within the Windows kernel.
The Role of Kubernetes and Cloud Integration:
Docker's integration with Kubernetes, a leading container orchestration platform, further underscores the importance of its underlying operating system. Kubernetes, like Docker, was originally designed to run on Linux. However, it now supports multi-platform orchestration, allowing clusters to include both Linux and Windows nodes.
Conclusion
The underlying operating system of Docker is predominantly Linux, whose advanced features such as namespaces, cgroups, and union filesystems provide the foundation for Docker's containerization capabilities. While Docker has extended its reach to macOS and Windows through virtualization and compatibility layers, the Linux kernel remains central to its functionality.
