Production Ready OpenStack - Recipes for Successful Environments

Chapter 2. Deploying OpenStack Using Staypuft OpenStack Installer

In this chapter, we will cover the following:

  • Setting up the environment
  • Installing Staypuft packages
  • Discovering hosts for provisioning
  • Creating a new OpenStack deployment
  • Configuring a network
  • Allocating hosts to roles
  • Configuring host networking
  • Deploying OpenStack

Introduction

Installing OpenStack manually, as outlined in Chapter 1, Introduction to OpenStack and its Deployment Using Packages, allows the maximum level of customization, but it introduces a level of difficulty to deploy OpenStack consistently across multiple nodes, as it requires performing countless manual steps repeatedly. Project Staypuft simplifies OpenStack production installations; Staypuft is a wizard-based installer that automates the OpenStack configuration and deployment process. Staypuft is a plugin built on top of Foreman, an open source life cycle management tool, and it leverages Foreman's capabilities. Staypuft can automatically discover and orchestrate the provisioning of new bare-metal controllers and computes. It can deploy highly available controllers with all required HAProxy and pacemaker configurations.

Setting up the environment

Before deploying Staypuft server and preparing it for a new OpenStack deployment, we need to prepare the environment with necessary prerequisites for the deployment.

Getting ready

In this chapter, we will use Staypuft to deploy controller/Neutron/Computes layout, we will need to prepare networks for the environment and prepare the host that will serve as the Staypuft host.

Networks layout

We will need to make sure that all machines are connected to a dedicated network that will be used for provisioning. The Staypuft host and Neutron node need to have access to a public network. All compute nodes and Neutron network node need to be connected to the tenant network. See the following diagram:

Networks layout

Provisioning PXE network

Staypuft automatically stands up a PXE environment with Cobbler, TFTP, DHCP, and DNS on the Staypuft host. Staypuft uses the provisioning network to deploy the base operating system of the hosts that serve as controllers, Neutron, and compute nodes and later...

Installing Staypuft packages

At this point, we have all the needed prerequisites configured and we should be ready to proceed installing Staypuft packages and running the Installer pre configuration script.

Getting ready

It is recommended to run on the latest update of the operating system. We can use yum to update the system:

[root@staypuft.example.com ~]# yum update

Use the yum install command to install the staypuft installer package, which brings all dependence packages.

[root@staypuft.example.com ~]# yum install foreman-installer-staypuft

How to do it…

The Staypuft installer takes care of installing Foreman and the Staypuft plugin on top of it. Then, it configures the host and Foreman, including all necessary networks, firewall, SELinux, and repository configurations, so the Staypuft host is ready to deploy new OpenStack deployments after the setup process.

  1. Execute the staypuft-installer command to install and setup Staypuft:
    [root@staypuft.example.com ~]# staypuft-installer
    
  2. Select...

Discovering hosts for provisioning

Before creating a new OpenStack deployment, we need to add hosts to Staypuft to be provisioned as OpenStack nodes. Staypuft uses the host's auto discovery via the PXE provisioning network.

Getting ready

We will need to access the Staypuft user interface and then make sure that the hosts we plan to deploy as Controller, Compute, and Neutron are ready for the deployment.

Accessing the Staypuft web user interface

Access the Staypuft web user interface. On completion of the previous section, staypuft-installer provided a URL, and the password for the admin account that was generated for the environment. Open your web browser and navigate to the URL that was provided by staypuft-installer. Log in with the Username admin and Password that was provided. In this example, we used the name http://Staypuft.example.com.

Accessing the Staypuft web user interface

In case you didn't make a note of the password that was generated, you can locate the file /etc/foreman/staypuft-installer.answers.yaml under...

Creating a new OpenStack deployment

At this point, we are ready to create a new OpenStack deployment and provision the Controller, Neutron, and Compute nodes. We will create a new deployment, configure general deployment settings, create and assign subnets and service networks. Then, we will configure Neutron, Glance, and Cinder services. When the deployment configuration is ready, we will assign hosts for each OpenStack role and deploy the environment.

How to do it...

Proceed with the following steps:

  1. Create a new deployment by navigating in the upper menu to OpenStack Installer | New Deployment.
    How to do it...
  2. Choose a new name for the deployment in the Name text and fill the description text.
  3. Select Controller/Compute layout in the High Availability section. If you would like to deploy highly available controllers layout, keep in mind that this layout requires at least three nodes for the Controller role.
  4. Choose RabbitMQ as the message provider. Staypuft can deploy RabbitMQ and QPID. Since RabbitMQ is more...

This book simplifies the learning process by guiding you through how to install OpenStack in a single controller configuration. The book goes deeper into deploying OpenStack in a highly available configuration. You'll then configure Keystone Identity Services using LDAP, Active Directory, or the MySQL identity provider and configure a caching layer and SSL. After that, you will configure storage back-end providers for Glance and Cinder, which will include Ceph, NFS, Swift, and local storage. Then you will configure the Neutron networking service with provider network VLANs, and tenant network VXLAN and GRE. Also, you will configure Nova's Hypervisor with KVM, and QEMU emulation, and you will configure Nova's scheduler filters and weights. Finally, you will configure Horizon to use Apache HTTPD and SSL, and you will customize the dashboard's appearance.

Who is this book for?

If you have a basic understanding of Linux and Cloud computing and want to learn about configurations that OpenStack supports, this is the book for you. Knowledge of virtualization and managing Linux environments is expected. Prior knowledge or experience of OpenStack is not required, although beneficial.

This is possibly one of the best handbooks available for those looking to get their feet wet with OpenStack. This book simplifies the complex quite nicely, and brings OpenStack deployments to the masses. On a personal note, I had the pleasure of seeing Arthur speak at a number of OpenStack Summits and events, and he is indeed a seasoned OpenStack professional. You want to read this book.

This book is largely a copy-paste of the official OpenStack installation guide for RHEL/CentOS systems.I guess I don't see a point to this book, the methods described in the book are already outdated ('openstack-config' isn't generally recommended to be used anymore).Some of the book's diagrams seem to be copied from OpenStack's official guides as well (maybe the author created the ones that the official OpenStack site uses, who knows).The main OpenStack documentation seems better organized than this book as well, and user's would probably be better served by a constantly updated resource, than a e-book which will be out of date by the time I even submit this review.http://docs.openstack.org/admin-guide-cloud/Overall, this book doesn't seem to cover anything noteworthy that official docs don't do a better job explaining. There aren't any new concepts in this book, no novel deployment strategies, only covers Redhat/CentOS, not Ubuntu or any other distribution (which the official OpenStack documentation covers all major distributions).

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
