Mission of training-labs
OpenStack cluster for training
● Automated setup
● Minimal hardware requirements
● Minimal dependencies
● Easy to remove
● Support for all major platforms: Linux, OS X, Windows
● Predictable, reproducible environment
● Match install-guide
● Offline installation! Hands-on sessions will never fail.
Currently supported OpenStack core services
● Keystone
● Horizon
● Glance
● Nova
● Neutron
● Cinder
● Heat
● Ceilometer

Workflow
Speed up
● basedisk○ updated base operating system○ OpenStack distro packages needed for all services○ only basedisk needs Internet connection○ basedisk to built cluster: 15-30 minutes
● node snapshots○ for each service installation○ restore partially installed cluster○ restore clean cluster after playing with it
Training Labs
Debugging tools
● log files (hypervisor calls, client-side scripts)
● launch_instance: build CirrOS guest VM
● repeat-test○ from scratch or from named snapshot (resets all VMs accordingly)
○ retrieves and archives log files (including server logs from node VMs)
install-guide● Restart the Networking services:
# service neutron-plugin-openvswitch-agent restart# service neutron-l3-agent restart# service neutron-dhcp-agent restart# service neutron-metadata-agent restart
echo "Restarting the network service."sudo service neutron-plugin-openvswitch-agent restartsudo service neutron-l3-agent restart
echo -n "Checking VLAN tags."# Wait for "tag:" to show upuntil sudo ovs-vsctl show|grep tag:; do
echo -n "."sleep 1
doneif sudo ovs-vsctl show|grep "tag: 4095"; then
# tag: 4095 indicates an errorecho >&2 "ERROR: port is in limbo and won't recover:"grep tag=4095 /etc/openvswitch/conf.db >&2exit 1
fi
echo -n "Getting router namespace."until ip netns|grep qrouter; do
echo -n "."sleep 1
donensrouter=$(ip netns|grep qrouter)
sudo service neutron-dhcp-agent restart

osbash and DevStack compared● DevStack
○ A tool aimed at OpenStack developers○ Uses latest source code from OpenStack repos○ User manages VMs
● osbash
○ A tool for OpenStack training○ Uses OpenStack packages from distro repos○ Automated management of virtual machine lifecycle○ Predictable environment for training
Roadmap for Training Labs● Finalize ports to Kilo and Liberty
● Improve KVM support
● Create CI system for training-labs and install-guides
● Port of host-side code to Python
● Support additional distros
● Baremetal deployment (Raspberry Pi2 ?)

Deploying osbash● Prerequisite
○ Download and install VirtualBox
● How to run the scripts○ Get and unpack tarball (Linux, OS X) or zip file (Windows)○ Go to the osbash folder
■ $ cd osbash○ Run the script
■ For linux as Mac OS X● $ ./osbash -b cluster
■ For Windows● Double-click Windows batch files
Deploying osbash● Prerequisite
○ Download and install VirtualBox
● How to run the scripts○ Clone the repository
■ $ git clone git://git.openstack.org/openstack/training-labs○ Go to the osbash folder
■ $ cd training-labs/labs/osbash/○ Run the script
■ For linux as Mac OS X● $ ./osbash -b cluster
■ For Windows● Create wbatch scripts on Linux/OS X: $ ./osbash -w cluster
