# This is our main installation script. It's function is basically read the main configuration file
# in "./configs" directory, source all installation variables, and then install every component in
# the right order. Normally the order is as follows:
# 1.- Basic python libraries and other base packages. Libvirt/qemu/kvm, sudo, etc.
# 2.- Message Broker (either rabbit or qpid - only if it's a controller).
# 3.- Database installation, configuration and provisioning (if it's a controller).
# 4.- Extra libraries (only on debian/ubuntu based installs).
# 5.- Keystone (if it's a controller, installs the sofwtare, in other cases, justo provision the en-
#     vironment files
# 6.- Application Modules (if apply and where apply) in order:
#     - Swift.
#     - Glance.
#     - Cinder.
#     - Neutron.
#     - Nova.
#     - Ceilometer (with gnocchi and aodh).
#     - Heat.
#     - Trove.
#     - Sahara.
#     - Manila.
#     - Designate.
#     - Magnum.
#     - Horizon.
# 7.- Basic SNMP Support.
# 8.- Post-install with maintenance crontabs and scripts
#
# This installation tool will allow you to construct an OpenStack cloud with the following possible
# configurations:
# - Monolitic ALL-IN-ONE OpenStack Server (basically an ALL-Services controller/compute).
# - Distributed Cloud with a Controller/Compute and several compute nodes.
# - Distributed Cloud with a Pure Controller and several compute nodes.
# - Fully distributed cloud with controller services distributed in many nodes, and several compute nodes
#
# The behaviour of this script is completelly controlled in the ./config/main-config.rc file. By properlly
# configuring this file, you can deploy your cloud the way you want.
