Chapter 18. Manage Tenant Quotas

This chapter explains the management of Tenant/Project quotas for OpenStack Networking components.

OpenStack Networking (neutron) supports the use of quotas to constrain the number of resources created by tenants/projects. For example, you can limit the number of routers a tenant can create by changing the quota_router value in the neutron.conf file:

quota_router = 10

This configuration limits each tenant to a maximum of 10 routers.

Further quota settings are available for the various network components:

18.1. L3 quota options

Quota options available for L3 networking: quota_floatingip - Number of floating IPs allowed per tenant. quota_network - Number of networks allowed per tenant. quota_port - Number of ports allowed per tenant. quota_router - Number of routers allowed per tenant. quota_subnet - Number of subnets allowed per tenant. quota_vip - Number of vips allowed per tenant.

18.2. Firewall quota options

Quota options governing firewall management: quota_firewall - Number of firewalls allowed per tenant. quota_firewall_policy - Number of firewall policies allowed per tenant. quota_firewall_rule - Number of firewall rules allowed per tenant.

18.3. Security group quota options

Quota options for managing the permitted number of security groups: quota_security_group - Number of security groups allowed per tenant. quota_security_group_rule - Number of security group rules allowed per tenant.

18.4. Management quota options

Quota options for administrators to consider: default_quota - Default number of resource allowed per tenant. quota_health_monitor - Number of health monitors allowed per tenant.
