🚁 Preview Apps (or review apps)

[bryantbrock]

I wanted to have preview apps for my epic-stack (started) remix application. I found this article on fly.io that outlines getting started, but a few modifications were needed so I'd thought I'd share my final GH Action for anyone interested. Would be cool to see this up on the epic-stack starter.

Hey! This is very cool! Would you be willing to make a PR to add an example to https://github.com/epicweb-dev/epic-stack/blob/main/docs/examples.md?

Not 100% certain I want it by default (breaks out of the free tier), but I think it would be really cool as an example.

I created this PR superfly/fly-pr-review-apps#50 to manage build args and secrets with fly. I've been waiting for 2 months for a review tho.. if you know someone at fly it could be nice that he/she asks someone to take a look to the several PRs waiting on this repo

To not break out with free tier here are two ideas that I personally use:

• require a label in order to deploy to preview
• implemented an autosleep: after 1 hour for example the server shuts down and therefore scales down to 0
