Install dnsmasq on macos m1

brew-install-dnsmasq-macos-m1.md

Install dnsmasq with brew:

$ brew install dnsmasq

Setup *.test hosts with:

$ echo 'address=/.test/127.0.0.1' >> /opt/homebrew/etc/dnsmasq.conf

If want to use other device to resolv nameserver ( default only 127.0.0.1 )

$ echo 'listen-address=127.0.0.1,192.168.1.2' >> /opt/homebrew/etc/dnsmasq.conf

note:
- as dnsmasq configuration recommendation is to include 127.0.0.1
- 192.168.1.2 is ip of macos
- Change address above to macos IP 'address=/.test/192.168.1.2'
- For Macos WiFi sharing add more IP 'listen-address=127.0.0.1,192.168.1.2,192.168.2.1' the IP 192.168.2.1 is the gateway IP WiFi sharing

Start service:

$ sudo brew services start dnsmasq

If found Error like this:

$ Error: Failure while executing; /bin/launchctl bootstrap system /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist exited with 37.

Try to restart services:

$ sudo brew services restart dnsmasq

Should see:

$ Successfully started dnsmasq (label: homebrew.mxcl.dnsmasq)

Add resolver:

$ sudo mkdir /etc/resolver

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

Test:

$ ping abcd.ef.test

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
