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. Health monitors do not consume resources, however the quota option is available due to the OpenStack Networking back end handling members as resource consumers. quota_member - Number of pool members allowed per tenant. Members do not consume resources, however the quota option is available due to the OpenStack Networking back end handling members as resource consumers. quota_pool - Number of pools allowed per tenant.
