How to generate an app using Instant Rails
Once you’ve purchased a license from the Instant Rails website, you’re ready to generate your Dockerized Rails app. The Instant Rails app generation command is as follows.
$ curl get.instantrails.app|sh -s <app name> <license key>
If for example your license key is
8d103360d1c68a5d4fb398b15d3d8a60 and you wanted to create an app
hello_world, you would run the following command.
$ curl get.instantrails.app|sh -s hello_world 8d103360d1c68a5d4fb398b15d3d8a60
This command will generate a Rails app for you, download and unzip it, then start a Rails server that you can visit.
