# This file can be used directly by 'phd', see 'build-all.sh' in this
# directory for how it can be invoked. The only requirement is a list
# of nodes you'd like it to modify.
#
# The scope of each command-block is controlled by the preceeding
# 'target' line.
#
# - target=all
# The commands are executed on evey node provided
#
# - target=local
# The commands are executed from the node hosting phd. When not
# using phd, they should be run from some other independant host
# (such as the puppet master)
#
# - target=$PHD_ENV_nodes{N}
# The commands are executed on the Nth node provided.
# For example, to run on only the first node would be target=$PHD_ENV_nodes1
#
# Tasks to be performed include:
# - Setting up haproxy to expose nova and horizon
# - Installing and configuring bind for DNS
# - Installing and configuring DHCP. For your own sanity, we define rules that allow you to predictably calculate MAC addresses for the guests.
# - Turning off auto-generation of resolv.conf so we can point to our local DNS server
