Container
A lightweight, standalone executable package of software that includes everything needed to run an application.
Definition
A container is a standardized, lightweight unit of software that packages code and all its dependencies so the application runs quickly and reliably from one computing environment to another. Unlike virtual machines, containers share the host OS kernel and are much more lightweight. Containers are created from images and managed by container runtimes like Docker. They provide consistency across development, testing, and production environments and form the foundation of microservices architectures.
Example
“A developer creates a Docker container for a Node.js app that runs identically on their laptop, the CI server, and the production Kubernetes cluster.”
Usage Examples
- 1
“The team applied container best practices to improve their cloud computing outcomes significantly.”
- 2
“Understanding container is essential for anyone building a career in IT & Technology.”
