can phoenix.new do everything to setup docker:jlesage/firefox for me?

This is a Remote Browser Isolation option. Firefox in cloud instead of firefox on laptop. I can spell docker and have a vague idea about containers. I’m trying to come in under $7/mo instead of a low end premade service that almost meets my needs for a few hours of use weekly. I gave up trying to get this to work on render, and zscaler is way overkill. Not a developer of any flavor.
