What we cover
Master Docker containers from scratch - run, build, debug, and manage the full container lifecycle used on every production server at Swiggy, Razorpay, and CRED.
Key words used in this concept — explained simply, no jargon.
A lightweight, isolated process running on a shared Linux kernel using namespaces and cgroups — providing filesystem, network, and process isolation without the overhead of a full virtual machine.
A read-only, layered filesystem snapshot that serves as the template for creating containers. Each layer represents a Dockerfile instruction and is cached and reused across builds to speed up image creation.
