Finally got the Dokku Ruby on Rails example app working 😭 Apparently I just needed to reboot the droplet? `curl` to my droplet's IP wasn't working, `dokku ports:list ruby-getting-started` didn't show it listening on port 80, `dokku ports:add ruby-getting-started http:80:5000` resulted in an error saying nginx wasn't running. Rebooting seemed to fix it. Next up is trying to deploy my Go backend with Dokku. Destroyed the ruby demo dokku app. Resized my DO droplet to the $6/mo one.
