Heroku Preboot

  • rails, ruby, heroku, technical

Heroku now allows zero-downtime deployment with their Preboot add-on! How did I miss that?? This will be great for some of my Ruby on Rails apps.

I’ve been having to roll my own using nifty unicorn tricks for even the simplest site where I wanted to ensure zero-downtime on deploy. Not every site needs it, but some definitely do.

I’ve been building an API for a mobile app recently, and that doesn’t want to go down! I’m usually happy to deploy overnight if I need to, but the ability to deploy anytime is nice for me (and my sleep patterns).
