Base Image

Definitions

1. The starting container image on top of which additional layers, dependencies, and application code are built. Base image choice affects size, security posture, package availability, startup behavior, and how often downstream images need rebuilding for updates.

   In plain English: The foundational container image used as the starting point for building another image.

   Example: "They replaced the bulky base image with a slimmer distro so build times dropped and fewer unnecessary packages shipped in production."
