Ansible playbook to initialize new undercloud for tripleo

undercloud-playbook.yaml

#
# Ansible playbook to prepare the undercloud machine.
# Will preform all steps until custom steps are to be taken --
# which are: providing a custom undercloud.conf and running
# openstack install undercloud command and so on...
# Root SSH access to the remote machine has to be configured.
# Edit vars as necessary.
#

# If this is the first time you are using Ansible on a host,
# make sure to install it (via yum for example), then create
# config file in your working directory (home?) ansible.cfg
# The contents should be something like:
# [defaults]
# inventory = [path-to-inventory-file]
#
# Then create an inventory file containing the name of the
# undercloud machine (instack?)
# To run the playbook you can issue:
# ansible-playbook -v [playbook-file-name.yaml]
#
