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 VXLAN and GRE tenant networks using Open vSwitch

Neutron supports creating layer 2 network overlays for tenant network traffic on top of Layer-3 networks using network tunneling technologies. In this recipe, we will configure Neutron to create GRE and VXLAN network overlays using Open vSwitch (OVS).

We will configure a topology of Neutron Networking Node that runs the Neutron Server main service, Open vSwitch agent, other Neutron service agents, such as L3 and DHCP. All OpenStack compute nodes run the open vSwitch agent to manage local L2 networks.

Getting ready

In this recipe, we will configure Neutron to use the ML2 plugin with an Open vSwitch mechanism driver, and tenant network type of VXLAN and GRE. Since the ML2 plugin supports configuring multiple type drivers, we will configure Neutron to support both GRE and VXLAN simultaneously. In this recipe, we assume that all OpenStack services, such as Keystone and nova, and components, such as message broker and database...
