Npm Install not working with User Data File

June 28, 2017 134 views
Node.js DigitalOcean Ubuntu 16.04

Hi all I'm looking to install dependencies using npm install, then run casperjs, all from droplet creation using --user-data-file:
doctl compute droplet create test1 --image node --size 4gb --region nyc1 --ssh-keys (omitted) --user-data-file su.sh --wait -t $DAT
with su.sh being:

apt-get update
apt-get --assume-yes install npm
sudo npm install -g phantomjs-prebuilt
sudo npm install -g casperjs
apt-get --assume-yes install libfontconfig

I'm also not able to redirect the output of those commands to files using > or 2>.
Is there a better way to install dependencies and start scripting in an automated way using Digital Ocean, or can my process be modified to success?

#!/bin/bash
apt-get update
apt-get -y install npm libfontconfig
npm install -g phantomjs-prebuilt
npm install -g casperjs
