I used to have this with homeassistant and zwavejs. Every time I'd pull a new homeassistant, the zwave integration would fail, because it required a newer version of zwavejs. Taught me to build the chain of services into one docker-compose, so they'd all update together. That's become one of the rationales for me to use docker: got a chain of dependent processes? wrap them in a docker so you're working with (probably) the same dependencies as the devs.
My other rationale is just portability, and docker is just one of many solutions there. In my little home environment, where servers are either retired desktops or gee-that-seems-cool SBCs, it's nice to be able to easily move stuff independent of architecture or OS.
