Setup dnsmasq on OS X

dnsmasq OS X.md

Never touch your local /etc/hosts file in OS X again

To setup your computer to work with *.test domains, e.g. project.test, awesome.test and so on, without having to add to your hosts file each time.

Requirements

• Homebrew
• Mountain Lion -> High Sierra

Install

brew install dnsmasq

Setup

Create config directory

mkdir -pv $(brew --prefix)/etc/

Setup *.test

echo 'address=/.test/127.0.0.1' >> $(brew --prefix)/etc/dnsmasq.conf

Change port for High Sierra

echo 'port=53' >> $(brew --prefix)/etc/dnsmasq.conf

Autostart - now and after reboot

sudo brew services start dnsmasq

Add to resolvers

Create resolver directory

sudo mkdir -v /etc/resolver

Add your nameserver to resolvers

sudo bash -c 'echo "nameserver 127.0.0.1" > /etc/resolver/test'

Finished

That's it! You can run scutil --dns to show all of your current resolvers, and you should see that all requests for a domain ending in .test will go to the DNS server at 127.0.0.1

N.B. never use .dev as a TLD for local dev work. .test is fine though.

If you are running into issue why dig or nslookup still doesn't work with your domain. It turns out they don't use the official system resolver on Mac OS (ref: https://stackoverflow.com/questions/50914268/os-x-etc-resolver-dev-isnt-working-why-not )

Therefore, to test a domain . Use this

dscacheutil -q host -a name argocd.ml-dev.test
