Notes on dnsmasq setup

The easiest way to set up dns aliases is probably to use dnsmasq. This will require...

• remove the dependency on bind (added bonus of removing a submodule)
• deploy dnsmasq (currently using debops.dnsmasq, but maybe easier to manage if we roll our own?)
• figure out a standard for a unique site domain. Currently using testsite.tunapanda.org
• set up A record for main.$domain hostname
  • Should be do-able with host-record = main.testsite.tunapanda.org,main,10.0.2.15, except the version in Ubuntu Precise doesn't seem to support host-record!
  • An alternative, maybe a better one, that is supported is interface-name=main.testsite.tunapanda.org,eth1, which dynamically sets the name to whatever IP is on eth1.
    • This may be another reason to not use debops, since it seems to always use host-record, though we could also just use it without any attempt at hostname setup, then put hostname setup in /etc/dnsmasq.d/01-main_host.conf
• set up CNAME records for services
  • Can be done by creating /etc/dnsmasq.d/02-alias_$name.conf with cname=testalias.testsite.tunapanda.org,main.testsite.tunapanda.org.
  • However, this seems to only work if the target record is in /etc/hosts.dnsmasq (which rather defeats the point of interface-name. :(
