The way we store DB and MQ URLs in the API database causes issues for some deployments (and deployment tools) which want to use per-host credentials or remote hostnames. Since all the URLs loaded from the database are the same on all systems, this becomes very difficult and some have even resorted to using client-based aliasing underneath Nova and just providing URLs that reference those aliases. This makes our CellMapping object load the URLs out of the database, and apply variable substitution from the CONF-resident base URLs for any fields provided. Such functionality will let operators define per-host credentials in [database]/connection, for example, and have those applied to the database_connection URLs loaded from CellMapping records.

The URLs in cell mapping records may now include variables that are filled
|
|
from the corresponding default URL specified in the host's configuration
|
|
file. This allows per-host credentials, as well as other values to be set
|
|
in the config file which will affect the URL of a cell, as calculated when
|
|
loading the record. For ``database_connection``, the ``[database]/connection``
|
|
URL is used as the base. For ``transport_url``, the ``[DEFAULT]/transport_url``
|
|
is used. For more information, see the cells configuration docs:
