This article compares traditional hypervisor‑based virtualization with Docker container technology, detailing how containers use shared kernels, namespaces, cgroups, AUFS, and device mapper to achieve lightweight isolation and higher resource efficiency.
This article explains Docker’s architecture, focusing on the role of the AUFS union file system in image layering, storage drivers, and how containers share and update layers to achieve efficient deployment and storage management.
This article explains the concepts, usage, and performance characteristics of AUFS, a Union File System used in Linux and Docker, providing examples of mounting, branch permissions, whiteout handling, and configuration options, while discussing its role in container image layering.
This article explains Docker’s layered file‑system concepts, compares AUFS, devicemapper, and other storage drivers, demonstrates mounting with AUFS, shows how read‑only and read‑write layers enable container isolation, and details how image commits create new layers for version control.
This article traces Docker's origins, explains its core container technologies such as namespaces, cgroups, and AUFS, demonstrates a simple Hello World deployment, and reviews related sub‑projects and security features, showing how Docker reshaped cloud‑native application delivery.
This article provides a comprehensive overview of Docker, covering its historical background, core container technologies such as Linux namespaces, cgroups, and AUFS, a practical Hello World example, and recent sub‑projects, illustrating how Docker reshapes cloud‑native development and operations.
