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 a network

In this step, we will create the subnets we plan to use for OpenStack services and assign network roles to the corresponding subnets. At a later stage, we will assign the newly created subnets to physical network interfaces, which will be used for these network roles.

How to do it...

Proceed with the following steps:

  1. On the network configuration screen, which appeared in addition to the existing 'default' subnet, click on the New Subnet button and create an additional subnet for the tenant's traffic. This subnet will be used for instances' internal communication.

    Network name: Tenant network

    Network address:

    Network mask:

    IPAM: none

    Boot mode: DHCP

    This configuration uses an existing DHCP service on the subnet to assign IP address to network interfaces attached.

  2. Drag and drop the Tenant network role from the default subnet to the newly created Tenant subnet, as can be seen in the following image:

  3. Create an additional subnet for external public network....
