Maybe because a single app on a single server rarely stays a single app. And while the landscape has generally improved, and imo is better under Linux than windows... there's nothing worse than trying to get a handful of .Net and Java applications installed and working in concert on a Windowss server with multiple framework versions for the differing apps. Let alone harder dependencies.

Docker for Windows Containers itself was a horrible exercise in frustration just because of it's own dependency issues, and I thought it was a bad idea from the start because of it, and it dilluted Docker for Linux IMO.

Docker/Containers and Compose are pretty great to work with, assuming your application has dependencies like Databases, Cache, etc. Not to mention options such as separating TLS certificate setup and termination from the application server(s) or scaling to larger orchestration options... though I haven't gone past compose for home-lab or on my own server(s).

I can also better position data storage and application configurations for backup/restore by using containers and volumes next to the compose/config. I've literally been able to migrate apps between servers with compose-down, rsync, dns change, compose up -d on the new server. In general, it's been pretty great all around.
