Copier lien

OpenStack Networking (neutron) supports the use of quotas to constrain the number of resources created by tenants/projects.

  • You can set project quotas for various network components in the /var/lib/config-data/neutron/etc/neutron/neutron.conf file.

    For example, to limit the number of routers that a project can create, change the quota_router value: 

    quota_router = 10

    In this example, each project is limited to a maximum of 10 routers.

For a listing of the quota settings, see sections that immediately follow.
