Presumably later in this config, you do something with $instanceId,
and you have a way to handle it not being set.

Use "map" to turn your list of domains into the appropriate
instanceId. Then change your server_name directive not to set that
variable.

Something like:

map $host $instanceId {
hostnames;
default "";
~^i(?P<a>\d+)\.domain$ $a;
super-user.com 1;
another-domain.net 1;
custom.domain 2;
}

server {
listen *:80 default;
server_name whatever;
...
# use $instanceId if it is set
}

You could also set the default $instanceId to a particular value that
means "not set", and have the rest of the system use that value for an
"unknown" account.


The alternative approach would be to have a separate server{} block
for each account, with lots of duplication that is handled by your
config-generator-from-template system. But f you want a single server{}
block, the above is probably the simplest way.

Good luck with it,
