I tend to use Docker heavily as basically just a cross-distro, isolated package and process manager that also presents config in a reasonably consistent manner.

I tend to use Docker heavily as basically just a cross-distro, isolated package and process manager that also presents config in a reasonably consistent manner. It's wildly better than dealing with "native" distro packages, unless you are all in on doing everything The Correct Way on a particular distro and have tooling in place to make that not suck. That it happens to use containers barely matters to me.
