Container Image

Container Image

Definition

A container image is a lightweight, standalone, executable package that includes application code, runtime, libraries, environment variables, and configuration. Images are built in layers, with each instruction in a Dockerfile adding a new read-only layer.

Images are stored in registries and instantiated as running containers by runtimes like Docker or containerd.
