What is the Underlying Technology of Docker?
Introduction: Docker underlying technology, containerization, offers a powerful solution to the age-old problem of "it works on my machine" by ensuring consistent environments from development to production. Kubernetes Online Training The Essence of Containerization: At the heart of Docker lies containerization , a lightweight form of virtualization that allows multiple containers to run on a single host machine. Unlike traditional virtual machines (VMs) that require a complete operating system for each instance, containers share the host OS kernel, making them more efficient and faster to start. Containers encapsulate an application and its dependencies into a single package, ensuring that it runs uniformly across various environments. Key Components of Docker: Docker Engine: The core of Docker, the Docker Engine, is responsible for creating and managing containers. It consists of a server (a daemon process), a REST API for interacting with the daemon, and a co...
