# Overview

The cioctl command-line is used to manage cluster level resources, such as drives and nodes, which are part of the 'infrastructure'. This interface is generally used by operators unless a developer is managing their own cluster.

Like the cio command-line, the cioctl interface comes installed. The cioctl command-line has many subcommands, such as cioctl create, cioctl init, cioctl reboot, etc.

Running cioctl by itself displays help showing all available subcommands. In addition, you can run any command with the --help flag to output help information. For example, try running cioctl drive --help. This outputs a one sentence usage info and lists all options the command accepts. Details on various cio commands are available in the left navigational section of this site.
