Comparatively speaking, going back to how we deployed applications 10 years ago is the dark ages. Having everything in containers is objectively easier both from a getting started and ongoing maintenance standpoint.

Now: making minimal edits to a provided compose file for initial configuration, run command to spin up everything application needs, and you're done.

Then: install application package onto system (best: from developer package source/better: from old version in operating system repo/worst: by compiling from source after locating all dependencies and running make install), setting up any necessary databases or storage by hand, editing configuration files that are hopefully in /etc if the developer thinks the FHS is something to be honored, setting up init scripts/unit files so the application starts up in the environment it wants and when you want, and finally running the command which starts the application (which is probably distro specific).

And that's not even getting into updates. I'll take pulling the latest version of the container and restarting over app specific update instructions any day of the week. Life is too short for putting up with that kind of minutia.
