OpenStack public DNS plugins

This package provides a collection of plugins to simplify the use of public DNS names for OpenStack virtual machine instances.

Each OpenStack network can have a configured dns_domain. Virtual machine instances launched within that network will have a hostname constructed from the network's dns_domain and appropriate DNS records will be created automatically.

For example: if an instance named testvm is launched in a network with the DNS domain example.org then the instance will be given the DHCP hostname testvm.example.org and the DNS A and AAAA records for testvm.example.org will be added to the DNS zone.

Installation

The easiest approach is to install the prebuilt RPM from the COPR repository.

Configuration

In /etc/neutron/plugin.ini in the [ml2] section, change the extension_drivers list to include publicdns instead of dns_domain_ports (or dns). For example:

[ml2]
extension_drivers = port_security,publicdns

In /etc/neutron/dhcp_agent.ini in the [DEFAULT] section, change dhcp_driver from neutron.agent.linux.dhcp.Dnsmasq to openstack_publicdns.neutron.dhcp.Dnsmasq. For example:

[DEFAULT]
dhcp_driver = openstack_publicdns.neutron.dhcp.Dnsmasq

In /etc/designate/designate.conf, in the [service:central] section, change storage_driver from sqlalchemy to publicdns. For example:

[service:central]
storage_driver = publicdns
