KNIFE-ENVIRONMENT(1)

NAME
knife-environment - The man page for the knife environment subcommand.

An environment is a way to map an organization's real-life workflow to what can be configured and managed when using 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's 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 server.

This subcommand has the following syntax:

$ knife environment [ARGUMENT] (options)
