Docker is far cleaner than native installs once you get used to it. Yes native installs are nice at first, but they aren’t portable, and unless the software is built specifically for the distro you’re running you will very quickly run into dependency hell trying to set up your system to support multiple services that all want different versions of libraries. Plus what if you want or need to move a service to another system, or restore a single service from a backup? Reinstalling a service from scratch and migrating over the libraries and config files in all of their separate locations can be a PITA.

It’s pretty much a requirement to start spinning up separate VMs for each service to get them to not interfere with each other and to allow backup and migration to other hosts, and managing 50 different VMs is much more involved and resource-intensive than managing 50 different containers on one machine.

docker compose pull/up/down is pretty much all you need, wrap it in a small shell script and you can bring up/down or update every service with a single command. Also if you use bind mounts and place them in the directory for the service along side the compose file, now your entire service is self-contained in one directory. To back it up you just “docker compose down”, rsync the directory to the backup location, then “docker compose up”. To restore you do the exact same thing, just reverse the direction of the rsync. To move a service to a different host, you do the exact same thing, just the rsync and docker compose up are now being run on another system.

Docker lets you compact an entire service with all of its dependencies, databases, config files, and data, into a single directory that can be backed up and/or moved to any other system with nothing more than a “down”, “copy”, and “up”, with zero interference with other services running on your system.
