Runtime Environment
Noun · Development
Definitions
The complete set of software, libraries, configuration, and system resources available to an application during execution — including the runtime itself, environment variables, installed packages, OS services, and hardware capabilities. Docker containers are a common way to package a reproducible runtime environment.
In plain English: Everything a program needs to run — the software, settings, and system resources that surround it during execution.
Example: "The bug only reproduces in the production runtime environment because it depends on a Linux-specific locale setting missing from our macOS dev machines."
