cat-dns Docker Image
This Docker image makes it relatively trivial to run cat-dns. All that kitty goodness wrapped up in a container.
Running on macOS
As an example, if you want to switch up Google's homepage (and everything under
.google.com, basically) for images of cats then do this:
echo 'nameserver 127.0.0.1\nport 10053' | sudo tee /etc/resolver/google.com
Now run up a container using this image:
docker run -d -p 10053:53/udp --name cat-dns yankcrime/cat-dns
And browse to http://google.com:
🐳 + 🐈 = ❤️
Running on anything else
I'll just assume you know what you're doing.
