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.

Configuring Glance with the Swift backend

If Swift Object Storage is in place, Glance can use the existing Swift cluster as a datastore to store virtual machine images. In this recipe, we will configure the Glance backend driver for swift object storage.

Getting ready

Before configuring Glance Swift backend, we need to make sure that the Database, message broker and Keystone are set for Glance, and both glance-api.conf and glance-registry.conf are configured correctly to use them.


It is recommended to make sure that the configuration option filesystem_store_datadir in glance-api.conf is commented out, as it should not be called when filesystem driver is not used.

How to do it...

Follow these steps to configure Glance with the Swift backend:

  1. Using the openstack-config command, edit the glance-api configuration file which is under default section and set default_store to swift:

    default_store = swift
  2. Make sure that the stores option includes swift store under glance_store section as follows...
