features:
|
|
- When booting an instance, its sanitized 'hostname' attribute is now used to
|
|
populate the 'dns_name' attribute of the Neutron ports the instance is
|
|
attached to.
|
|
This functionality enables the Neutron internal DNS service to know the
|
|
ports by the instance's hostname. As a consequence, commands like
|
|
'hostname -f' will work as expected when executed in the instance.
|
|
When a port's network has a non-blank 'dns_domain' attribute, the port's
|
|
'dns_name' combined with the network's 'dns_domain' will be published by
|
|
Neutron in an external DNS as a service like Designate. As a consequence,
|
|
the instance's hostname is published in the external DNS as a service.
|
|
This functionality is added to Nova when the 'DNS Integration' extension
|
|
is enabled in Neutron.
|
|
The publication of 'dns_name' and 'dns_domain' combinations to an external
|
|
DNS as a service additionally requires the configuration of the appropriate
|
|
driver in Neutron.
|
|
When the 'Port Binding' extension is also enabled in Neutron, the
|
|
publication of a 'dns_name' and 'dns_domain' combination to the external
|
|
DNS as a service will require one additional update operation when Nova
|
|
allocates the port during the instance boot. This may have a noticeable
|
|
impact on the performance of the boot process.
