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 Neutron VLAN provider network with ML2 and LinuxBridge

Neutron supports utilizing a range of provider network VLANs that were prepared for us beforehand by the network administrator. We will configure Neutron to use the VLAN networks in the range to segregate between different Neutron networks. While creating new Neutron networks, Neutron will dedicate a VLAN from the range for each new network. The hosts use network namespaces for each network to segregate networks between virtual machine instances running on the same host.

Getting ready

In this recipe, we will configure Neutron to use the ML2 plugin with the LinuxBridge mechanism driver, and the VLAN tenant network type. We assume all OpenStack services, such as Keystone and nova, and components, such as message broker and database, are installed and configured. Neutron is already set to utilize them.

In this recipe, we will use the VLAN range of 100 to 200, which is preset by the network administrator.
