Gudrun Wolfgram 08f0c4aa46 Cloud Admin Guide CLI chapter 
Moving (copying) Admin User Guide CLI content to
the Cloud Admin Guide as a part of the reorganization
goal. This patch does not include any new or original
content.

This patch is Part 1 to create a new command-
line client section for Admin Users in the Cloud Admin
Guide, as disucssed in the User Guide Specialty team
meetings.

1) Creating a new CLI section with cli.rst

2) Moving the non common files from user-guide-admin to
admin-guide-cloud, along with their sub files. (Rename
user-guide-admin files to user cli_ prefix in admin-
guide-cloud.)

Manage Compute service quotas

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

Compute quota descriptions

Quota name Description
cores Number of instance cores (VCPUs) allowed per tenant.
fixed-ips Number of fixed IP addresses allowed per tenant. This number must be equal to or greater than the number of allowed instances.
floating-ips Number of floating IP addresses allowed per tenant.
injected-file-content-bytes Number of content bytes allowed per injected file.
injected-file-path-bytes Length of injected file path.
injected-files Number of injected files allowed per tenant.
instances Number of instances allowed per tenant.
key-pairs Number of key pairs allowed per user.
metadata-items Number of metadata items allowed per instance.
ram Megabytes of instance ram allowed per tenant.
security-groups Number of security groups per tenant.
security-group-rules Number of rules per security group.

View and update Compute quotas for a tenant (project)

To view and update default quota values

  1. List all default quotas for all tenants:

    $ nova quota-defaults

    For example:

    $ nova quota-defaults
+-----------------------------+-------+
| Quota                       | Limit |
+-----------------------------+-------+
| instances                   | 10    |
| cores                       | 20    |
| ram                         | 51200 |
| floating_ips                | 10    |
| fixed_ips                   | -1    |
| metadata_items              | 128   |
| injected_files              | 5     |
| injected_file_content_bytes | 10240 |
| injected_file_path_bytes    | 255   |
| key_pairs                   | 100   |
| security_groups             | 10    |
| security_group_rules        | 20    |
+-----------------------------+-------+

  2. Update a default value for a new tenant.

    $ nova quota-class-update --KEY VALUE default

    For example:

    $ nova quota-class-update --instances 15 default

To view quota values for an existing tenant (project)

  1. Place the tenant ID in a usable variable.

    $ tenant=$(openstack project show -f value -c id TENANT_NAME)

  2. List the currently set quota values for a tenant.

    $ nova quota-show --tenant $tenant

    For example:

    $ nova quota-show --tenant $tenant
+-----------------------------+-------+
| Quota                       | Limit |
+-----------------------------+-------+
| instances                   | 10    |
| cores                       | 20    |
| ram                         | 51200 |
| floating_ips                | 10    |
| fixed_ips                   | -1    |
| metadata_items              | 128   |
| injected_files              | 5     |
| injected_file_content_bytes | 10240 |
| injected_file_path_bytes    | 255   |
| key_pairs                   | 100   |
| security_groups             | 10    |
| security_group_rules        | 20    |
+-----------------------------+-------+

To update quota values for an existing tenant (project)

  1. Obtain the tenant ID.

    $ tenant=$(openstack project show -f value -c id TENANT_NAME)

  2. Update a particular quota value.

    $ nova quota-update --QUOTA_NAME QUOTA_VALUE TENANT_ID

    For example:

    $ nova quota-update --floating-ips 20 $tenant
$ nova quota-show --tenant $tenant
+-----------------------------+-------+
| Quota                       | Limit |
+-----------------------------+-------+
| instances                   | 10    |
| cores                       | 20    |
| ram                         | 51200 |
| floating_ips                | 20    |
| fixed_ips                   | -1    |
| metadata_items              | 128   |
| injected_files              | 5     |
| injected_file_content_bytes | 10240 |
| injected_file_path_bytes    | 255   |
| key_pairs                   | 100   |
| security_groups             | 10    |
| security_group_rules        | 20    |
+-----------------------------+-------+

    Note

    To view a list of options for the quota-update command, run:

    $ nova help quota-update

View and update Compute quotas for a tenant user

To view quota values for a tenant user

  1. Place the user ID in a usable variable.
