NAME

knife-environment - The man page for the knife environment subcommand. \$1 \n[an-margin] level \n[rst2man-indent-level] level margin: \n[rst2man-indent\n[rst2man-indent-level]] - \n[rst2man-indent0] \n[rst2man-indent1] \n[rst2man-indent2]

An environment is a way to map an organization\(aqs real-life workflow to what can be configured and managed when using Chef server. Every organization begins with a single environment called the _default environment, which cannot be modified (or deleted). Additional environments can be created to reflect each organization\(aqs patterns and workflow. For example, creating production, staging, testing, and development environments. Generally, an environment is also associated with one (or more) cookbook versions.

The knife environment subcommand is used to manage environments within a single organization on the Chef server.
