Init terminating in do_boot in Elixir 1.9

[marocchino]

erlang 22.0.7
elixir 1.9.1

I am trying to test release.
I can success with build. but, It can not start with some error messages.

{"init terminating in do_boot",{'cannot get bootfile','/Users/marocchino/Documents/backend/_build/prod/rel/backend/bin/start.boot'}}
init terminating in do_boot ({cannot get bootfile,/Users/marocchino/Documents/backend/_build/prod/rel/backend/bin/start.boot})

Crash dump is being written to: erl_crash.dump...done

BTW, start.boot file was exists in release directory.

$ ls _build/prod/rel/backend/bin
backend     backend.bat
$ ls _build/prod/rel/backend/releases/0.1.0/
backend.rel        elixir             env.sh             releases.exs       start.script       start_clean.script vm.args
consolidated       env.bat            iex                start.boot         start_clean.boot   sys.config

Do I need more path setting?

update: that part was wrong. I update that It is little progress.

export RELEASE_DISTRIBUTION=name

but still hanging on start. I can call with rpc but, no 4000 port response.
It occurs when I generate a project with --no-webpack option.

It was just endpoint config.

Distillery not start app Phoenix

It’s probably because “server: true” is not configured on the endpoint. By default, in dev environment phoenix server is only started if you start the app with mix task, as in “iex -S mix phx.server” or “mix phx.server”… If you just start the app with “iex -S mix” no server starts unless you tell Phoenix to start it automatically. This is precisely the same case with releases. If you intend to start your app in dev mode as a release, flip the “server: true” flag in confing, just like it is in p…

problem resolved.
