# 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):
$ export GEM_HOME=/tmp/somedir
$ gem install r10k
$ sudo -E /tmp/somedir/bin/r10k puppetfile install -v
$ sudo cp -r packstack/puppet/modules/packstack /usr/share/openstack-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 | FERNET | UUID | FERNET |
| glance | file | swift | file |
| nova | X | X | X |
| neutron | X | X | X |
| lbaasv2 | | X | |
| cinder | X | | |
| ceilometer | | | X |
| aodh | | | X |
| gnocchi | | | X |
| heat | | | X |
| swift | | X | |
| sahara | | X | |
| trove | | X | |
| horizon | X | | |
| manila | X | | |
| nagios | X | | |
| SSL | 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
