Production Ready OpenStack - Recipes for Successful Environments

By: Arthur Berezin

Overview of this book

OpenStack is the most popular open source cloud platform used by organizations building internal private clouds and by public cloud providers. OpenStack is designed in a fully distributed architecture to provide Infrastructure as a Service, allowing us to maintain a massively scalable cloud infrastructure. OpenStack is developed by a vibrant community of open source developers who come from the largest software companies in the world. The book provides a comprehensive and practical guide to the multiple uses cases and configurations that OpenStack supports. 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.

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:

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...
