varnish-fly.md

1. Create a new project with flyctl init by using the default Dockerfile option.
2. Create a new file called default.vcl with the following content:

   vcl 4.0;
   
   backend default {
       .host = "damp-sound-540.fly.dev:80";
   }
   

3. Update the Dockerfile to use the official varnish image:

   FROM varnish:6.4 
   COPY default.vcl /etc/varnish/
   

4. Run flyctl deploy.
