Packstack is a utility that uses Puppet modules to deploy various parts of OpenStack on multiple pre-installed servers over SSH automatically. Currently only Fedora, Red Hat Enterprise Linux (RHEL) and compatible derivatives of both are supported.

Example Usage

All in One

$ packstack --allinone

For detailed options, please refer to the Packstack documentation at https://github.com/openstack/packstack/blob/master/docs/packstack.rst

Controller / multiple compute nodes


Swift Proxy / multiple storage devices


Development : Getting started

Installation of Packstack

$ sudo yum install git python-yaml -y
$ git clone https://github.com/stackforge/packstack.git
$ cd packstack && sudo python setup.py install

Installation of openstack-puppet-modules (Required if running packstack from source)

$ sudo python setup.py install_puppet_modules

Using an answer file

$ packstack --gen-answer-file=answers.txt

Then edit answers.txt as appropriate e.g.

  • Set CONFIG_SSH_KEY to a public ssh key to be installed to remote machines
  • Edit the IP address to anywhere you want to install a piece of opentack on another server
  • Edit the 3 network interfaces to whatever makes sense in your setup




Developers meet in #packstack-dev on Freenode for discussion.

End-user questions are probably best answered in #openstack or #rdo

Packstack Development

Making your first contribution

The process you need to follow in order to contribute to packstack is the same as the openstack core projects, documented here http://wiki.openstack.org/HowToContribute the steps to follow look something like this

Sign the CLA

Get the code

$ git clone https://github.com/stackforge/packstack.git 
$ cd packstack

Make a topic branch:

$ git checkout -b my_topic

Make your change

$ hack, hack, hack !! ;-)

Commit your change

$ git commit -a 

Submit your change for review

$ git review 

Wait for people on gerrit https://review.openstack.org/#/q/status:open+project:stackforge/packstack,n,z to review your change, if it needs to be altered simply amend your commit and submit it for review again

$ git add -p
$ git commit --amend
$ git review

Git branches

There is a branch for each openstack major release, this branch starts off is life as master, once development of the next release starts, it will be renamed and then master will be the branch for the next openstack release e.g. once we start juno development, master will branch off a juno branch. Then

  • juno → should only accept bug fixes and exceptional approved new features, these should be merged into master first if appropriate
  • master → new features for juno and bugs

Note : (be careful to send your changes to the correct branch and also that your basing any commits on a parent from the correct branch)

  • To send review request for the master branch
$ git review 
  • To send review request for the stable branch
$ git review juno


Bugs are tracked in Launchpad (New bug)


All commits should be reviewed and approved by at least one core packstack member (ideally 2 for any commit more then a trivial change) and author of a commit shouldn't approve their own code.

New Features

New features go into the master branch. There may be new features committed to a stable branch but these should be the exception and not the norm.


Open review requests https://review.openstack.org/#/q/status:open+project:stackforge/packstack,n,z

Packstack Core

You do not need to be a core member to packstack in order to contribute code. Members of packstack-core can approve commits in gerrit to be merged into the code, new members to packstack-core should be actively (and reliably) reviewing commits in gerrit before being considered. New members will be invited to join. Core members can be found here
