The nova-manage command
=======================

Introduction
~~~~~~~~~~~~

The nova-manage command is used to perform many essential functions for
administration and ongoing maintenance of nova, such as user creation,
vpn management, and much more.

The standard pattern for executing a nova-manage command is:
``nova-manage <category> <command> [<args>]``

For example, to obtain a list of all projects:
``nova-manage project list``

Run without arguments to see a list of available command categories:
``nova-manage``

Categories are user, project, role, shell, vpn, and floating. Detailed descriptions are below.

You can also run with a category argument such as user to see a list of all commands in that category:
``nova-manage user``

These sections describe the available categories and arguments for nova-manage.

Nova User

``nova-manage user admin <username>``

``nova-manage user exports <username>``

``nova-manage user list``

    Outputs a list of all the user names to the screen.

``nova-manage user modify <accesskey> <secretkey> <admin?T/F>``

    Updates the indicated user keys, indicating with T or F if the user is an admin user. Leave any argument blank if you do not want to update it.
	
Nova Project

``nova-manage project add <projectname>``

    Add a nova project with the name <projectname> to the database.

``nova-manage project create <projectname>``

``nova-manage project delete <projectname>``

    Delete a nova project with the name <projectname>.

``nova-manage project environment <projectname> <username>``

    Exports environment variables for the named project to a file named novarc.
    
``nova-manage project list``

    Outputs a list of all the projects to the screen.

``nova-manage project quota <projectname>``

    Outputs the size and specs of the project's instances including gigabytes, instances, floating IPs, volumes, and cores.

Role names can be one of the following five roles: admin, itsec, projectmanager, netadmin, developer. If you add the project name as the last argument then the role is assigned just for that project, otherwise the user is assigned the named role for all projects.

Concept: Flags
--------------

python-gflags


Concept: Plugins
----------------

* Managers/Drivers: utils.import_object from string flag
* virt/connections: conditional loading from string flag
* db: LazyPluggable via string flag
* auth_manager: utils.import_class based on string flag
* Volumes: moving to pluggable driver instead of manager
* Network: pluggable managers
* Compute: same driver used, but pluggable at connection


Concept: IPC/RPC
----------------

Rabbit!


Concept: Fakes
--------------

* auth
* ldap


Concept: Scheduler
------------------

* simple
* random


Concept: Security Groups
------------------------

Security groups


Concept: Certificate Authority
------------------------------

Nova does a small amount of certificate management.  These certificates are used for :ref:`project vpns <../cloudpipe>` and decrypting bundled images.


Concept: Images
---------------

* launching
* bundling
