How to run Laravel on Google Cloud Run

I am trying to figure out the simplest way to get a new Laravel 8 application running on Google Cloud Run. Has anybody done this before?

I have been through many tutorials and posts but can't figure out how to get it working. I'm relatively new to containers and Docker so this is making it difficult for me to figure this out.

I have found some images related to laravel on Docker Hub, but I don't fully understand how to use them within my own application, or how to set them up to work with Cloud Run.

I am using Laravel sail locally, which I thought would make for an easy deployment to production, but I am starting to understand that sail is only for local testing, not production.

I am really just trying to find a list of steps needed to get a fresh Laravel 8 application running on Cloud Run. No database, no cache, nothing else needed. I just want to be able to load the welcome screen for Laravel 8 on Cloud Run. This has proven to be a pretty confusing quest.

Any advice?
