This article provides a comprehensive overview of Docker, explaining its lightweight container model, client‑server architecture, key Linux kernel features such as namespaces and cgroups, image layering, networking, and the three‑stage process of building, distributing, and running containers.
This article explains how to analyze and optimize Spring Boot Docker images by using the new layer‑building feature in Spring Boot 2.3, restructuring Dockerfiles, and employing multi‑stage builds to eliminate duplicate layers, dramatically shrink image size, and speed up image pushes.
This article explains Docker's layered image storage, shows how improper layering inflates image size and download time, and provides a practical design method using shared base layers to streamline CI/CD pipelines and improve resource efficiency.
This article explains Docker's container engine, its layered image storage mechanism, and how leveraging these layers within DevOps pipelines can reduce redundancy, improve update efficiency, and optimize resource usage, illustrated with practical experiments and design guidelines for scalable image management.
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.
