Packstack

Utility to install OpenStack on Red Hat based operating system. See other branches for older OpenStack versions. Details on how to contribute to Packstack may be found in the Packstack wiki at https://wiki.openstack.org/wiki/Packstack Additional information about involvement in the community around Packstack can be found at https://openstack.redhat.com/Get_involved

This utility can be used to install OpenStack on a single or group of hosts (over ssh).

This utility is still in the early stages, a lot of the configuration options have yet to be added.

Installation of packstack:

$ yum install -y git
$ git clone git://github.com/openstack/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

Option 1 (all-in-one)

$ packstack --allinone

This will install all OpenStack services on a single host without prompting for any configuration information. This will generate an "answers" file (packstack-answers-<date>-<time>.txt) containing all the values used for the install.

If you need to re-run packstack, you must use the --answer-file option in order for packstack to use the correct values for passwords and other authentication credentials:

$ packstack --answer-file packstack-answers-<date>-<time>.txt

Option 2 (using answer file)

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

Then edit ans.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 OpenStack on another server
  • Edit the 3 network interfaces to whatever makes sense in your setup

you'll need to use a icehouse repository for example for RHEL

$ CONFIG_REPO=http://repos.fedorapeople.org/repos/openstack/openstack-icehouse/epel-6/

$ packstack --answer-file=ans.txt

Option 3 (prompts for configuration options)

$ packstack

that's it, if everything went well you can now start using OpenStack

$ cd
$ . keystonerc_admin
$ nova list
$ swift list  # if you have installed swift

Config options

  • CONFIG_NOVA_COMPUTE_HOSTS :
    • A comma separated list of ip addresses on which to install nova compute
  • CONFIG_SWIFT_STORAGE_HOSTS :
    • A comma separated list of swift storage devices
      • 1.1.1.1: create a testing loopback device and use this for storage
      • 1.1.1.1/sdb: use /dev/sdb on 1.1.1.1 as a storage device

Logging

The location of the log files and generated puppet manifests are in the /var/tmp/packstack directory under a directory named by the date in which Packstack was run and a random string (e.g. /var/tmp/packstack/20131022-204316-Bf3Ek2). Inside, we find a manifest directory and the openstack-setup.log file; puppet manifests and a log file for each one are found inside the manifest directory.

Debugging

To make Packstack write more detailed information into the log file you can use the -d switch:

$ packstack -d --allinone

Developing

Warning: this procedure installs openstack-puppet-modules containing code that has not been upstreamed and fully tested yet and as such will not be as robust as the other install procedures. It is recommended to install from RPM instead.

To ease development of Packstack and openstack-puppet-modules, it can be useful to install from git such that updates to the git repositories are immediately effective without reinstallation of packstack and openstack-puppet-modules.

To do this, start with a minimal Fedora 21 installation. Then remove any relevant packages that might conflict:

$ yum -y erase openstack-{packstack*,puppet-modules}

Disable SELinux by changing "enforcing" to "permissive" in /etc/sysconfig/selinux, then reboot to allow service changes to take effect and swap over networking. Then install packages:

$ yum -y install git python-setuptools

And install RDO:

$ yum -y install https://rdo.fedorapeople.org/rdo-release.rpm
$ yum -y update

Now we get openstack-puppet-modules. Because python setup.py install_puppet_modules from Packstack copies rather than linking, this is not entirely straightforward:

$ git clone https://github.com/redhat-openstack/openstack-puppet-modules
$ cd openstack-puppet-modules
$ git checkout master-patches
$ mkdir /usr/share/openstack-puppet
$ ln -sv /root/openstack-puppet-modules /usr/share/openstack-puppet/modules

Then we get Packstack, and perform a similar dance:

$ yum install -y python-crypto python-devel libffi-devel openssl-devel gcc-c++
$ git clone https://github.com/openstack/packstack
$ cd packstack
$ python setup.py develop
$ cd /usr/share/openstack-puppet/modules
$ ln -sv /root/packstack/packstack/puppet/modules/packstack

And we're done. Changes to the contents of Packstack and openstack-puppet-modules repositories are picked up by the Packstack executable without further intervention, and Packstack is ready to install.

Puppet Style Guide

IMPORTANT https://docs.puppetlabs.com/guides/style_guide.html

Please, respect the Puppet Style Guide as much as possible !

Running local Puppet-lint tests

It assumes that both bundler as well as rubygems (and ruby) are already installed on the system. If not, run this command:

$ sudo yum install rubygems rubygem-bundler ruby ruby-devel -y

Go into the Packstack root directory.

$ cd packstack/

A Rakefile contains all you need to run puppet-lint task automatically over all the puppet manifests included in the Packstack project.

$ ls -l packstack/puppet/templates/

and

$ ls -l packstack/puppet/modules/

The default puppet-lint pattern for .pp files is **/*.pp. So there is no need to go inside those directories to run puppet-lint !

$ mkdir vendor
$ export GEM_HOME=vendor
$ bundle install
$ bundle exec rake lint

Packstack integration tests

Packstack is integration tested in the OpenStack gate and provides the means to reproduce these tests on your environment if you wish.

This is the current matrix of available tests:

- scenario001 scenario002 scenario003
keystone X X X
glance file swift file
nova X X X
neutron X X X
cinder X
ceilometer X
aodh X
gnocchi X
heat X
swift X
sahara X
trove X
horizon X
 manila X
 nagios X

To run these tests:

export SCENARIO="scenario001"
./run_tests.sh

run_tests.sh will take care of installing the required dependencies, configure packstack to run according to the above matrix and run the complete installation process. If the installation is successful, tempest will also run smoke tests.

By default, run_tests.sh will set up delorean (RDO Trunk) repositories. There are two ways of overriding default repositories:

export DELOREAN="http://someotherdomain.tld/delorean.repo"
export DELOREAN_DEPS="http://someotherdomain.tld/delorean-deps.repo"
./run_tests.sh

You can also choose to disable repository management entirely:

<setup your own custom repositories here>
export MANAGE_REPOS="false"
./run_tests.sh
