How do i start my erlang app after rebar3 as prod tar?

[oladipo]

I have generated a .tar file with rebar3 for my erlang app.

I need to know what are the possible ways to start the app on my production server from the extracted tar.gz file.

Not sure how much help my answer will be, but since this is an old question, I'll give a shot. IMO since a good chance, good sysadmins will know about "make" / "mingw-make" or something similar. I usually stick this piece of code in.

run:
    ${ERL} -pa ./_build/default/lib/yourapp_app/ebin -s yourapp_startme

Maybe not the absolute best way to run an app (for applications modules), but I see it as an idiot proof method for non-Erlangers. If all they have to run in is $ make run. Of course, you can take this one example and expand it.

I also write a small "boot" script for my project so that everything runs perfectly.

-module(myapp_startme).

-export([start/0]).

start() ->
    ok = application:start(sasl),
    ok = application:start(yourapp_app).

Thanks everyone,

I found out a way that works for me.

$ ./rel/app/bin/app start

apparently my inability to start the app earlier on production was because of an unrelated error. I fixed the error and was good to go.

Thanks,
