wildcard DNS record on OS X in localhost development with dnsmasq

wildcard DNS in localhost development

$ brew install dnsmasq
$ cp /usr/local/opt/dnsmasq/dnsmasq.conf.example /usr/local/etc/dnsmasq.conf
  • edit /usr/local/etc/dnsmasq.conf
  • start dnsmasq
$ sudo brew services start dnsmasq
  • any time we change dnsmasq.conf we have to re-start dnsmasq:
$ sudo launchctl stop homebrew.mxcl.dnsmasq
$ sudo launchctl start homebrew.mxcl.dnsmasq
  • For OS X to resolve requests from *.local to localhost we need to add a resolver:
$ sudo mkdir /etc/resolver
$ sudo touch /etc/resolver/local
  • edit /etc/resolver/local
  • re-start the computer to enable the resolver

@slavikme by what metric it would be the "best"? Because .localhost is also reserved for exactly that purpose (it is literally in the same article you have posted).

Using *.localhost or *.test is nearly the same, with few small differences:

  1. test is a bit shorter - so it's somewhat a plus.
  2. When using localhost as TLD, and accessing it from other machine on the same network, it causes some conflicts with other local machines.
