Charles E. Rolke commented on DISPATCH-1585:
--------------------------------------------
[~lulf]
Proposing a solution in two parts:
* Add an *aliases* field to vhost to hold a list of hostnames that would all
resolve to using the vhost. The _vhost hostname_ is now just a placeholder and
not a real remote host name.
{code:java}
["vhost", { "hostname": "tenant1", "aliases": ["internal.example.com",
"public.example.com"], "allowUnknownUser": true, // ... }]
{code}
* In multi tenant setups the _vhost hostname_ is prepended to the autoLink
name instead of the _hostname_ field of the remote AMQP Open.
For accounting and statistics the vhost has one identifier (the hostname) and
one configuration set but it would apply to all the remote hosts in the aliases
list.
The aliases list is mutable the same as the rest of the settings in the vhost.
This creates new opportunities for misconfiguration. For instance, multiple
vhosts claim the same alias host address. Those details are still TBD pending
discussion of the basic proposal.

> At present, a multitenant router listener will prefix addresses with the
> hostname in the AMQP Open. However, given a configuration where it is
> desirable to expose a router address space for multiple DNS names, any
> address, linkRoute and autoLink configuration will need to be duplicated for
> each DNS name. This complicates router configuration significantly.
>
> Instead, having a way to specify which prefix to apply for a multitenant
> listener would allow reusing the same address, autoLink and linkRoute
> configuration for multiple listeners.
