I’ve read and reread, listened and relistened to info on docker/containers and I still feel like I’m missing something tbh.

Let’s say you have a docker container for something and it’s for a Linux distro, that won’t run on another OS, will it? Maybe not even a different Linux distro from the one it was made for (e.g. Ubuntu or Arch or Fedora or whatever).

To go off your example, Docker’s not like an expansion module to make your Switch games work on a PlayStation or Xbox…Right? There seems to be some kind of mixed messaging on this, the way they’re so readily recommended (which seems to be related to a presumption of familiarity that often isn’t there toward those inquiring).

I guess I’ve also been confused because like…Shouldn’t old installers handle bundling or pulling relevant dependencies as they’re run? I’d imagine that’s where containers’ security benefits come into play though, alongside being virtualized processes if I’m not mistaken.
