Container image

Meaning in software engineering, with examples

nounCore term

In software engineering, container image means: A read-only package with an application, its libraries and settings, used as the template from which containers are started.

In Turkish: konteyner imajı, kapsayıcı görüntüsü, imaj

How it is used

You build an image, tag it with a version, push it to a registry and pull it on servers. People often just say 'image' or 'Docker image'. Small images download and start faster.

Example sentences

  1. The new container image is 300 MB smaller because we switched to a slim base image.

  2. Always tag the container image with the commit hash, not just 'latest'.
