That is basically my use-case. You add a DB service (or two), DNS, reverse proxy, Redis, Memcached, etc… maybe some containers for additional proprietary backend services like APIs, and then the application themselves that need those things to run… it adds up FAST. The advantage is that you can have multiple projects all running simultaneously and you can add/remove/swap them pretty easily.
RAM is cheap. There is no excuse for shipping a 8GB computer… even if it’s mostly going to be used for family photos and internet.
