# Salt stack master and minion procedure, short version:
#
# - On the Master:
#
#     wget -O - http://bootstrap.saltstack.org | sudo sh -s -- -M git v0.17.0
#     sudo sh -c 'echo "master: INTERNAL_IP_GOES_HERE" >> /etc/salt/minion.d/master.conf'
#     sudo service salt-minion restart
#     sudo service salt-master restart
# 
# - On the Minions:
#
#     wget -O - http://bootstrap.saltstack.org | sudo sh -s -- git v0.17.0
#     sudo sh -c 'echo "master: INTERNAL_IP_GOES_HERE" >> /etc/salt/minion.d/master.conf'
#
# - On the Master, continue with:
#
#     sudo salt '*' pkg.install python-pip,python-virtualenv
#     sudo salt '*' pkg.latest_version python-git
# 
#   - Copy contents of this file in a salt-master node in `master.d/` folder
#     with a file name ending by `.conf`, e.g.: `/etc/salt/master.d/sample.conf`
#
#   - Restart the services
#
#     salt '*' service.restart salt-minion
#     salt-call service.restart salt-master
