how to set supervisor to run a shell script

Question

Setting up a Dockerfile to install node prereqs and then set up supervisor in order to run the final npm install command. Running Docker in CoreOS under VirtualBox.

I have a Dockerfile that sets everything up correctly:

FROM ubuntu
MAINTAINER <<Me>>

# Install docker basics
RUN echo "deb http://archive.ubuntu.com/ubuntu precise main universe" > /etc/apt/sources.list
RUN apt-get update
RUN apt-get upgrade -y

# Install dependencies and nodejs
RUN apt-get update
RUN apt-get install -y python-software-properties python g++ make
RUN add-apt-repository ppa:chris-lea/node.js
RUN apt-get update
RUN apt-get install -y nodejs

# Install git
RUN apt-get install -y git

# Install supervisor
RUN apt-get install -y supervisor
RUN mkdir -p /var/log/supervisor

# Add supervisor config file
ADD ./etc/supervisord.conf /etc/supervisor/conf.d/supervisord.conf

# Bundle app source
ADD . /src

# create supervisord user
RUN /usr/sbin/useradd --create-home --home-dir /usr/local/nonroot --shell /bin/bash nonroot
RUN chown -R nonroot: /src

# set install script to executable
RUN /bin/chmod +x /src/etc/install.sh

#set up .env file
RUN echo "NODE_ENV=development\nPORT=5000\nRIAK_SERVERS={SERVER}" > /src/.env

#expose the correct port
EXPOSE 5000

# start supervisord when container launches
CMD ["/usr/bin/supervisord"]

And then I want to set up supervisord to launch one of a few possible processes, including an installation shell script that I've confirmed to work correctly, install.sh, which is located in the application's /etc directory:

#!/bin/bash
cd /src; npm install
export PATH=$PATH:node_modules/.bin

However, I'm very new to supervisor syntax, and I can't get it to launch the shell script correctly. This is what I have in my supervisord.conf file:

[supervisord]
nodaemon=true

[program:install]
command=install.sh
directory=/src/etc/
user=nonroot

When I run the Dockerfile, everything runs correctly, but when I launch the image, I get the following:

2014-03-15 07:39:56,854 CRIT Supervisor running as root (no user in config file)
2014-03-15 07:39:56,856 WARN Included extra file "/etc/supervisor/conf.d/supervisord.conf" during parsing

2014-03-15 07:39:58,920 INFO spawnerr: can't find command 'install.sh'

Clearly, I have not set up supervisor correctly to run this shell script -- is there part of the syntax that I'm screwing up?

The best way that I found was setting this:

[program:my-program-name]
command = /path/to/my/command.sh
startsecs = 0
autorestart = false
startretries = 1
