Demo environment

DevStack

A bunch of scripts to build a full OpenStack environment
Used as
- Demo environment
- Part of the OpenStack project's functional testing
Single and multi node setup
Installs services from source
- from git master by default
- from stable branches by configuration, e.g. stable/newton
Documentation: http://docs.openstack.org/developer/devstack/

git clone https://git.openstack.org/openstack-dev/devstack

cd ./devstack
cp ./samples/local.conf .
nano ./local.conf

Nota

Students can use a different editor instead of nano with their own preferences (e.g. vi, emacs, or whatever they want).

./stack.sh

Nota

DevStack should already be installed in the VM image you downloaded. These instructions are provided for future reference in the case that students need to start from scratch.

Access the terminals the installed services are running in
Use command 'screen -ls' to see the running screen sessions
Use command 'screen -R <session name>' or 'screen -C stack-screenrc' to attach to or start a new session
For further commands see the User's Manual

Ensure you have the DevStack repository cloned to the VM where you would like to use it
Using the 'screen' command determine if there is a screen session running in your VM. If there is, attach to it. If not, start a new session.
Once attached to a screen session switch between the running services to get to your favorite service and try stopping and restarting the service.
Disconnect from your screen session and ensure it is still running in the background.
