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 local file backend

In this recipe, we will configure Glance backend to use local storage driver to store image files on the local disk.

Getting ready

Before getting started with configuring the Glance backend driver, we need to make sure that the database, message broker, and Keystone are set for Glance, and both glance-api.conf and glance-registory.conf are configured correctly to use them.

How to do it...

Perform the following steps to configure Glance with the local file backend:

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

    [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf default default_store file

  2. Make sure that stores option includes filesystem store, under glance_store section:

    [root@controller ~]# openstack-config --set /etc/glance/glance-api.conf glance_store stores glance.store.filesystem.Store

    Note

    Note: if you plan to use multiple back...
