James E. Blair df81542135 Use global generated groups in launch-node
When launching a server, ansible needs to know what groups the
new host is in so that it can copy the appropriate files.  Figuring
that out is done based on the groups.txt file and the expand-groups
script.  This change runs that script after creating a host, which
will update the global list of expanded groups.  That is then
symlinked into a temporary inventory directory used by launch-node.

The JobDir concept is borrowed from Zuul as a simple way of creating
and deleting at the appropriate time a complex temporary directory.

Create Server
=============

Note that these instructions assume you're working from this
directory on an updated local clone of the repository on the
puppetmaster, and that your account is a member of the admin
and puppet groups for access to their respective keys::

  sudo adduser $(whoami) admin
  sudo adduser $(whoami) puppet

(Remember to log out and back into your shell if you add yourself
to a group.)

To launch a node in the OpenStack CI account (production servers)::

  export OS_CLOUD=openstackci-rax
  export OS_REGION=DFW
  export FLAVOR="8 GB Performance"
  export FQDN=servername.openstack.org
  cd /opt/system-config/production/launch/
  ./launch-node.py $FQDN --flavor "$FLAVOR" \
    --cloud=$OS_CLOUD --region=$OS_REGION

To launch a node in the OpenStack Jenkins account (slave nodes)::

  export OS_CLOUD=openstackjenkins-rax
  export OS_REGION=DFW
  export FQDN=slavename.slave.openstack.org
  openstack image list
  export IMAGE='Ubuntu 12.04 LTS (Precise Pangolin) (PVHVM)'
  openstack flavor list
  export FLAVOR="8 GB Performance"
  ./launch-node.py $FQDN --image "$IMAGE" --flavor "$FLAVOR" \
     --cloud=$OS_CLOUD --region=$OS_REGION

Manually add the hostname to DNS (the launch script does not do so
automatically). Note that this example assumes you've already
exported a relevant FQDN and sourced the appropriate API credentials
above.

In order for Ansible to be able to send out the Puppet updates,
you also need the puppetmaster to accept the root SSH key for the
new server. So as root on the puppetmaster:

  ssh root@$FQDN

Verify the fingerprint of the new server and type "yes" to accept.
Then you can log out.

Add DNS Records
===============

There are no scripts to automatically handle DNS at the moment due to
a lack of library support for the new Rackspace Cloud DNS (with IPv6).
However, the launch-node script will print the commands needed to be
run to configure DNS for a newly launched server.  To see the commands
for an existing server, run:

  ./dns.py $FQDN
