[HCoop-Help] Elixir/Erlang Applications

[Jeffrey Drake]

I have attempted to deploy a simple application written in Elixir using the Phoenix framework, which ultimately uses the erlang vm. 

I cannot figure out exactly what is going wrong.

I have given the daemon user write access to a logs directory and scratch folder (although I cannot guarantee this is being used). I have built it on a debian wheezy vm, and packaged it with a mix release which includes everything to run it.

The shell script I made is based on phoenix deployment instructions and hcoop guides:

> #!/bin/sh
> 
> export MIX_ENV=prod
> export PORT=51666
> export COOKIE=$HOME/apps/gpsapp/scratch/.erlang.cookie
> 
> k5start -t -U -f /etc/keytabs/user.daemon/drakej -- gpsapp/bin/gpsapp $1
> 

(where $1 is start, stop, etc.)

But when I run it, I get an error that seems to indicate it can’t listen. I have tried my user and the daemon user. The port 51666 is registered on the control panel. 

Has anyone encountered a problem like this?

- Jeff.

The output follows.
