With Erlang/OTP 23.1 and relx 4.2 (included in Rebar3 3.14.3) it is now possible to conveniently run Erlang releases without relying on EPMD for opening a remote shell or clustering nodes. This is particularly going to make Erlang releases simpler to configure in locked down environments, and easier to use with containers. Erlang shell commands.
