These are a collection of scripts that install and configuration Openstack Juno on Ubuntu 14 and onwards, within an Emulab/Apt/Cloudlab testbed experiment.

Starting OpenStack

1. Go to cloudlab.us
2. Start an experiment with the pythia-openstack project.
3. Parameters: The only parameters tested to work are # of compute nodes and disk image. For disk image, use tracing-pythia-PG0//base-with-repos for both node types (compute/controller).
4. Select your cluster (I usually use Utah) and schedule creation/create immediately.
5. Wait for ~1 hours until you get an email saying openstack is ready. Before this, the setup will be unusable.

What is this repo

It is forked from https://gitlab.flux.utah.edu/johnsond/openstack-build-ubuntu and keeping it updated may be a good idea. The scripts to set up pythia are called setup-pythia.sh and setup-pythia-compute.sh, they should be self-explanatory. They pull the latest repos from github using ssh keys inside the disk image and install them to overwrite whatever the rest of the scripts install, also they partially install pythia.

When to update this

When a new openstack package is forked (e.g., to add more instrumentation), add it to setup pythia scripts similar to how nova is done currently. Also, use the pythia scripts to change the configuration of openstack services if necessary.

Using OpenStack

Inside the dotfiles repository, there should be some aliases (in cloudlab.bashrc). For example, create_vm pythia_status. Other than that, check openstack docs.
