Konténerkép

Konténerkép is a Hungarian term that translates to "container image." It refers to a self-contained unit of software that includes all the necessary code, runtime, system tools, system libraries, and settings to run an application. This concept is fundamental to containerization technologies like Docker, Kubernetes, and Podman.

The primary purpose of a konténerkép is to ensure that an application runs consistently across different computing environments, regardless of the underlying infrastructure. This is achieved by packaging the application and its dependencies into a standardized format. When a konténerkép is executed, it runs as an isolated process, preventing conflicts with other applications or the host operating system.

Konténerképek are built from a set of instructions, often defined in a Dockerfile or similar configuration file. These instructions specify the base operating system, additional software to install, code to copy, and commands to execute. Once built, the image is typically stored in a container registry, from which it can be pulled and deployed to various hosts. This immutability and portability make konténerképek highly valuable for modern software development and deployment practices, enabling faster iteration, easier scaling, and more reliable operations. They are a cornerstone of microservices architectures and cloud-native computing.
