Hi, I'm not sure if what I've been doing is right, but the following is a piece of code I use to refresh the master branch of every single repo under /opt/stack when I need to:

#!/usr/bin/env python
from os import listdir,chdir
from os.path import isdir,join
from subprocess import call
mypath='/opt/stack/'
onlydirs=[d for d in listdir(mypath) if isdir(join(mypath,d))]
for d in onlydirs:
  print "="*70
  print "Updating %s..." % join(mypath,d)
  chdir(join(mypath,d))
  call(["git","checkout","master"])
  call(["git","remote","update"])
  call(["git","pull","--ff-only","origin","master"])

Hope this helps and if there is a better way to do so please feel free to share. Thanks!

I guess you have checked the http://devstack.org/, right? Type cmd as follows.

git clone https://github.com/openstack-dev/devstack.git
cd devstack && ./stack.sh

For more details, you should read the stack.sh itself.

In your local.conf, add the below line. Then, DevStack will clone repositories of OpenStack again, when you try to run "./stack.sh" in next time.

And if you want to try Neutron Networking you need to set the following you localrc file .. or it will default to Nova networking. Also there is a Bug, so you need to enable the load balancer before you load up the Neutron network modules, if not you will get a bunch of python errors and things won't work.

The localrc file snip is below (disable nova networking first, load lbaas, then Neutron)

disable_servce n-net

enable_service q-lbaas
enable_service q-neutron
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
