Kollas mission is to provide production-ready containers and deployment tools for operating OpenStack clouds. Kolla Ansible is highly opinionated out of the box, but allows for complete customization. This permits operators with minimal experience to deploy OpenStack quickly and as experience grows modify the OpenStack<\/a> configuration to suit the operators exact requirements.<\/p>\n

Chapter One – Related Projects<\/b><\/b><\/h2>\n

This documentation is for Kolla Ansible. For information on building container images for use with Kolla Ansible<\/a>, please refer to the Kolla image documentation. Kayobe is a subproject of Kolla that uses Kolla Ansible and Bifrost<\/a> to deploy an OpenStack control plane to bare metal.<\/p>\n

Chapter Four – Administrator Guide<\/b><\/h2>\n

4.1 Admin Guides <\/b><\/p>\n

4.1.1 Advanced Configuration Endpoint Network Configuration<\/b><\/p>\n

When an OpenStack cloud is deployed, the REST API<\/a> of each service is presented as a series of endpoints. These endpoints are the admin URL, the internal URL, and the external URL.<\/p>\n

Kolla offers two options for assigning these endpoints to network addresses: – Combined – Where all three endpoints share the same IP address – Separate – Where the external URL is assigned to an IP address that is different than the IP address shared by the internal and admin URLs<\/p>\n

The configuration parameters related to these options are:\u00a0 – kolla_internal_vip_address –<\/span>net- work_interface <\/span>– kolla_external_vip_address – kolla_external_vip_interface<\/span><\/p>\n

For the combined option, set the two variables below, while allowing the other two to accept their default values. In this configuration all REST API requests, internal and external, will flow over the same network.<\/p>\n

kolla_internal_vip_address: “10.10.10.254”
\nnetwork_interface: “eth0”<\/p>\n

For the separate option, set these four variables. In this configuration the internal and external REST API requests can flow over separate networks.<\/p>\n

kolla_internal_vip_address: “10.10.10.254”
\nnetwork_interface: “eth0”
\nkolla_external_vip_address: “10.10.20.254”
\nkolla_external_vip_interface: “eth1”<\/p>\n

Fully Qualified Domain Name Configuration<\/b><\/p>\n

When addressing a server on the internet, it is more common to use a name, like www.example.net, instead of an address like 10.10.10.254. If you prefer to use names to address the endpoints in your kolla deployment use the variables:<\/p>\n
