We're now all-in on impress.openneo.net for this box!
One little wrinkle is that certbot was initially upset that I had
already uploaded the copy-pasted certs from the other box to here, at
the file path it expected to get to manage. So, I moved those to
`/srv/impress/shared/temp-certs`, and changed the nginx config
accordingly; and then deleted the original and let certbot control it!
Yay it's working! We set up the box, install Ruby, upload a placeholder app, set it up as a service, and get it hooked up to nginx!
Next, we'll add the script to upload the latest version of the site. We just need to slot it into `/srv/impress/current`, run `bundle install`, and that should basically be that! (Oh, and we need to compile production assets—I wonder if it's useful to do that on the dev machine instead of on the target? That might save us from needing to install Node. Or maybe we'll have to anyway!)
