On the DotDev.co blog today there's a post from Jordon Brill showing you how to manage custom VMs with Laravel Forge. In his particular setup, the VMs he was working with weren't ones created by Forge so he needed to do some custom work to integrate the two.
I had a legacy php application that I wanted to move to a newer version of php. This application is not built on Laravel but rather is a conglomerate of a bunch of different php scripts and pieces of different frameworks. We recently deployed a Laravel-based application to a server running on AWS via Laravel Forge and Laravel Envoyer and fell in love with the service. We were completely up and running in about 10 minutes and it was great.
This case, however, was a bit outside of the typical scenario since it was not a Laravel application and Forge wasn’t going to be creating the server on one of the built-in services that Forge has an integration with (Linode, DigitalOcean, and AWS).
He starts by creating a new VM instance of a Ubuntu-based Linux system. He then shows how to connect it up to Laravel Forge via the "Custom VPS" option. This provides you with a custom command and token to use to make the connection to manage the server via Forge from then on. He does point out a few "gotchas": that it all needs to be run as the "root" account and that you'll need to open SSH ports in your firewall (if you have one) to allow the Forge service access.
