To restart coredns after an upgrade:

Or, if you don't want/need a background service you can just run:

/usr/local/opt/coredns/bin/coredns -conf /usr/local/etc/coredns/Corefile

=⇒ Summary

🍺 /usr/local/Cellar/coredns/1.10.0: 7 files, 53.4MB

=⇒ Running `brew cleanup coredns`…

Disable this behaviour by setting HOMEBREW_NO_INSTALL_CLEANUP.

Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).

iMac ~ % sudo brew services restart coredns

Password:

Error: Running Homebrew as root is extremely dangerous and no longer supported.

As Homebrew does not drop privileges on installation you would be giving all build scripts full access to your system.

Error: Failure while executing; `/usr/local/bin/brew tap homebrew/services` exited with 1.
