Allow user to create default record on port creation from shared network
|
||||
========================================================================
|
||||
|
||||
https://bugs.launchpad.net/neutron/+bug/1843218
|
||||
|
||||
As discussed in the bug thread above, we could add the feature to allow a user
|
||||
to have default zone configured on a shared network.
|
||||
|
||||
Problem Description
|
||||
-------------------
|
||||
|
||||
On Neutron, when the DNS ML2 plugin is enabled, each user can manage their own network, and
|
||||
configure a dns_domain (i.e. example.com) for that network. The dns_domain (called zone) can
|
||||
be hosted in one and only one tenant. To create a record in a zone, the record's tenant must be
|
||||
the same as the zone's tenant. If a user creates a port in that network, it has to be the same
|
||||
tenant as zone to get the record created.
|
||||
|
||||
Network (A project) <~~> Port (B project) <==> Zone (B project) <==> Record (B project)
|
||||
|
||||
So we need to have all these resources hosted on the same project (port, zone and record) to
|
||||
get this feature working.
|
||||
|
||||
As ports are able to be created from several different projects in the case of a shared
|
||||
network, this feature doesn't work for that case.
|
||||
|
||||
|
||||
Proposed Change
|
||||
---------------
|
||||
|
||||
As described in the RFE, the idea is to let the network's admin user configure keywords in
|
||||
the default dns_domain on their network to allow zone to be different per user or per project.
|
||||
|
||||
Here are the accepted keywords :
|
||||
|
||||
- <project_id>
|
||||
- <project_name>
|
||||
- <user_name>
|
||||
- <user_id>
|
||||
|
||||
For instance, configuring <user_name>.<project_id>.example.com. as dns_domain on any
|
||||
network will allow users to have one default zone per user and per project, and then be able
|
||||
to create records.
|
||||
|
||||
::
|
||||
|
||||
$ source openrc_admin
|
||||
$ openstack network set --dns-domain "<user_name>.<project_id>.example.com." shared
|
||||
$ source openrc_demo
|
||||
$ openstack zone create --email dnsmaster@defaultzone.com UserName.HisProjectId.example.com.
|
||||
$ openstack port create --dns-name myport port
|
||||
|
||||
