This is pretty great advice to get into it. I previously ran 3 poweredge 2950s but have since switched to nothing self hosted and back to everything self hosted but on a much leaner setup with a NUC and 14tb WD my book drive with a dual Noctua 4020 fan shroud I 3d printed that it absolutely needed as I killed the original drive in two weeks.
My replica is just a 14tb in my desktop I run rsync to pull the data occasionally after checking SMART status on the primary. It’s not versioned or perfect but it works great to give me a chance to backup my jellyfin media. Everything I care about also gets backed up via restic.
Eventually plan to run a build with the Modcase MASS with multiple drives but for now this setup has been working fantastic.
I would imagine you could run into an issue like this building off an M1 or newer Mac and deploying to a Linux based env. We’ve run into a bit of an adjustment with our docker image builds where we need to set the buildarch or else it fails to deploy.
Our build times aren’t blazingly fast, typically around 4 minutes for npm/yarn build for frontend apps and loading the data to the image and any other extras like composer installs. Best time saving for us was doing a base image for all the dependency junk that we do a nightly on
