Designate: Interactive Workshop - Install and Operate - Openstack Summit, May 2015

Designate provides DNSaaS services for OpenStack.

This interactive workshop will guide attendees on how Designate can be installed with PowerDNS. For the purposes of the workshop the various designate components will be installed on a single node. Once installed it shows some of the V1 and V2 APIs for domain and record management. The workshop will conclude by using a tool like dig to retrieve the added records from the PowerDNS backend, showing a fully functional by-hand deployment.

The workshop will also cover the steps for contributing to the development of Designate.

Several of the Designate contributors will be on hand during the workshop to help attendees work through the deployment.

Tell designate what you want your ns records to be

designate server-create --name ns.example.com.

Additional Notes on the workshop

• A single node was used so that it is easier to control and easier for newbies to install.
