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.

Generating and configuring tokens PKIs

Keystone uses cryptographically signed tokens with a private key and are matched against x509 certificate with public key. Chatper 5, Glance Image Service discusses advanced configurations. In this recipe, we will use keystone-manage pki_setup command to generate PKI key pairs and configure Keystone to use it.

How to do it…

Proceed with the following steps:

  1. Generate PKI keys using the keystone-manage pki_setup command:

    [root@controller ~]# keystone-manage pki_setup --keystone-user keystone --keystone-group keystone


    In keystone-manage pki_setup, we use Keystone Linux user and group accounts, which were created when openstack-keystone packaged was installed.

  2. Change the ownership of the generated PKI files:

    [root@controller ~]# chown -R keystone:keystone 
    /var/log/keystone /etc/keystone/ssl/
  3. Configure Keystone service to use the generated PKI files:

    [root@controller ~]# openstack-config --set 
    /etc/keystone/keystone.conf  signing token_format PKI
