OpenStack Puppet samples

openstack-puppet-samples

Note from Iben: We will edit this to show a settings example for all-in-one OpenStack Kilo install on single NIC machine with only eth0.

This can work on a VM or Physical server and will take care of the work to swtich IP from eth0 DHCP to bridge static address. Thanks to Cloudbase for this work: cloudbase/openstack-puppet-samples

As an example we will show how this can be installed on Servers .76 and .77 so we need to allocate a range of IP addresses to each one. be sure to read all the steps below... here is a guide once you're ready to deploy.

• .76 - 10.241.1.220-224
• .77 - 10.241.1.225-229

NOTE: give each server their own private /24 subnet. These IP addresses will be used by the local DHCP server to automatically configure the network for the OpenStack VMs we instantiate on each node. Additionaly, running VM instances can be asssigned a floating IP from the public allocation pool allowing us to communicate with the VM from outside the OpenStack environment.

This example is for .76

$interface = 'eth0'
$ext_bridge_interface = 'br-ex'
$dns_nameservers = ['8.8.8.8', '8.8.4.4'] # update for your lab name servers
$private_subnet_cidr = '192.168.76.0/24' 
$public_subnet_cidr = '10.241.0.0/16'
$public_subnet_gateway = '10.241.254.253'
$public_subnet_allocation_pools = ['start=10.241.1.220,end=10.241.1.224']

This example is for .77

$interface = 'eth0'
$ext_bridge_interface = 'br-ex'
$dns_nameservers = ['8.8.8.8', '8.8.4.4'] # update for your lab name servers
$private_subnet_cidr = '192.168.77.0/24' 
$public_subnet_cidr = '10.241.0.0/16'
$public_subnet_gateway = '10.241.254.253'
$public_subnet_allocation_pools = ['start=10.241.1.225,end=10.241.1.229']

OpenStack Kilo Puppet manifests

This is a collection of Puppet resources meant to be useful for proof of concepts and similar scenarios where the goal is to deploy OpenStack in a quick and painless way, often on limited hardware resources.

All in One

Use this manifest to deploy OpenStack with:

• One single host
• One single NIC
• KVM hypervisor

The host can be either a physical or even a virtual machine, as long as it supports nested virtualization (e.g. VMWare Workstation / Player / Fusion / ESXi, KVM, etc).

OpenStack release

Kilo

OpenStack components

• Keystone
• Glance
• Nova / KVM
• Neutron / Open vSwitch
• Cinder / LVM
• Horizon

To be added soon:

• Swift
• Heat
• Ceilometer

Supported operating system

Ubuntu 14.04 LTS

Prerequisites

system should have a static IP address on eht0 - don't use DHCP

check that dns is properly setup in /etc/resolv.conf use public DNS like google 8.8.8.8 and 8.8.4.4

logged in as a user - run these command. (sudo is not needed if you are logged in as root)

sudo apt-get update -y
sudo apt-get install puppet -y
sudo puppet module install openstack/keystone --version ">=6.0.0 <7.0.0"
sudo puppet module install openstack/glance --version ">=6.0.0 <7.0.0"
sudo puppet module install openstack/cinder --version ">=6.0.0 <7.0.0"
sudo puppet module install openstack/nova --version ">=6.0.0 <7.0.0"
sudo puppet module install openstack/neutron --version ">=6.0.0 <7.0.0"
sudo puppet module install example42/network
sudo puppet module install saz/memcached

Edit the Manifest pp file

Modify the variables at the beginning of openstack-aio-ubuntu-single-nic.pp to match your environment where needed (see examples above).

Copy the manifest file to the system where we want to install openstack. The prerequisites must be installed already.

Run puppet to apply the manifest

sudo puppet apply --verbose openstack-aio-ubuntu-single-nic.pp

OpenStack environment

After applying the manifest, the environment is fully deployed and ready to be used. A Cirros image is included in Glance.

OpenStack Dahsboard (Horizon):

http://<openstack_host>/horizon

Login with either the "admin" or "demo" credentials. Default password is "Passw0rd" for both.

When booting instances, attach a nic to the "private" network.

Command line environment variables:

source /root/keystonerc_admin

or

source /root/keystonerc_demo

Others

If you are using ubuntu 14.04 after os is installed, the default ethX will be renamed into emX where the 'X' is digital number from 1 to N,here N stands for the last number of your NIC eg: nic8.

Then you should modify the puppet manifest file openstack-aio-ubuntu-single-nic.pp to replace all eth0 with emX eg: em1

sed -i s/eth0/em1/g openstack-aio-ubuntu-single-nic.pp

After the script is completed, you should restart your server to refresh all the OpenStack services to make it work.
