Manage Compute service quotas
=============================
As an administrative user, you can use the :command:`nova quota-*`
commands, which are provided by the ``python-novaclient``
package, to update the Compute service quotas for a specific project or
project user, as well as update the quota defaults for a new project.

To view and update default quota values
---------------------------------------
#. List all default quotas for all projects:
.. code-block:: console
$ nova quota-defaults
For example:
.. code-block:: console
$ nova quota-defaults
+-----------------------------+-------+
| Quota | Limit |
+-----------------------------+-------+
| instances | 10 |
| cores | 20 |
| ram | 51200 |

+-----------------------------+-------+
#. Update a default value for a new project.
.. code-block:: console
$ nova quota-class-update --KEY VALUE default
For example:
.. code-block:: console
$ nova quota-class-update --instances 15 default
To view quota values for an existing project
--------------------------------------------
#. Place the project ID in a usable variable.
.. code-block:: console
$ tenant=$(openstack project show -f value -c id TENANT_NAME)
#. List the currently set quota values for a project.
.. code-block:: console
$ nova quota-show --tenant $tenant
For example:
.. code-block:: console
$ nova quota-show --tenant $tenant
+-----------------------------+-------+
| Quota | Limit |

To update quota values for an existing project
----------------------------------------------
#. Obtain the project ID.

$ tenant=$(openstack project show -f value -c id TENANT_NAME)
#. Update a particular quota value.
.. code-block:: console
$ nova quota-update --QUOTA_NAME QUOTA_VALUE TENANT_ID
For example:
.. code-block:: console
$ nova quota-update --floating-ips 20 $tenant
$ nova quota-show --tenant $tenant
