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?
