I operate a couple of Elixir apps and so far a simple Makefile with a couple of shell scripts has been enough. This simplicity is due to the fact that the only external dependency is a database server, everything else (language runtime, web server, caching, job scheduling, etc.) is baked in the Elixir release. One unfortunate annoyance though is that Elixir releases are not portable and can't be cross-compiled (e.g. building on latest Ubuntu and deploying to Debian stable won't work) so we have to build them in a container matching the target OS version. So to be really honest I should mention that Docker is also part of our deployment stack, although we don't run it on production hosts.
