# nova-rootwrap

## Synopsis

    nova-rootwrap CONFIG_FILE COMMAND

## Description

nova-rootwrap is an application that filters which commands nova is allowed to run as another user.

To use this, you should set the following in `nova.conf`:

    rootwrap_config=/etc/nova/rootwrap.conf

You also need to let the nova user run nova-rootwrap as root in `sudoers`:

    nova ALL = (root) NOPASSWD: /usr/bin/nova-rootwrap /etc/nova/rootwrap.conf *

To make allowed commands node-specific, your packaging should only install `{compute,network}.filters` respectively on compute and network nodes, i.e. API nodes should not have any of those files installed.

Note

nova-rootwrap is being slowly deprecated and replaced by `oslo.privsep`, and will eventually be removed.
