+# Lab example 1 
+# 2019-02-08
+#
+# This example playbook has been tested with https://github.com/redhatNORDICS/consulting-lab/pull/38#issuecomment-461851756
+# A complete run like this takes around 1h, so it is a good idea to use `nohup &` or a terminal multiplexer like screen or tmux.
+#
+# It will turn a Hetzner host running the rescue boot to a labsetup with virtual networks
+# and ready to spin up VM's in matter of seconds. 
+# 
+# The process:
+# Once the hetzner installer is finished with the CentOS installation
+# it will start syncing down the latest RHEL 7Server repo.
+#
+# While the sync runs it will proceed to configure libvirt with networks,
+# OpenVPN and knockd.
+# 
+# The process is blocked until the reposync is complete. Once it has completed
+# the VM template will be created. This will serve as a base for all VM's that we create.
+#
+# With the template in place, it will then create all VM's defined in the [vms] group in the inventory.
+# The VM's are added to the in-memory inventory for further configuration and alsot to the static inventory/connections file.
+#
+# Next play is against the new VM's where the example just applies the motd role.
+#
+# Usage:
+# $ nohup ansible-playbook -i inventory/ lab1.playbook &
+
+
+# From rescue mode
