Instant CentOS Minion on Joyent
View joyent-instant-centos-salt-minion.sh
#!/bin/bash
#
# Setups up a new CentOS machine on Joyent running a Salt minion talking to your salt master. From there, you can do the rest of your setup work from the Salt Master.
# Requires Joyent Command Line SDK be installed as well as Node's jsontool (npm install jsontool)
# If you don't provide a Joyent ID, the code assumes the master is labeled with metadata "salt-role=master" or with "role=salt-master"
# Tweak these variables should have done anything creative with your salt setup
