About Adam Young

Once upon a time I was an Army Officer, but that was long ago. Now I work as a Software Engineer. I climb rocks, play saxophone, and spend way too much time in front of a computer.

Running Unit Tests on Old Versions of Keystone

Just because Icehouse is EOL does not mean no one is running it. One part of my job is back-porting patches to older versions of Keystone that my Company supports.

A dirty secret is that we only package the code needed for the live deployment, though, not the unit tests. In the case of I need to test a bug fix against a version of Keystone that was, essentially, Upstream Icehouse.

RBAC Policy Updates in Tripleo

Policy files contain the access control rules for an OpenStack deployment. The upstream policy files are conservative and restrictive; they are designed to be customized on the end users system. However, poorly written changes can potentially break security, their deployment should be carefully managed and monitored.

Since RBAC Policy controls access to the Keystone server, the Keystone policy files themselves are not served from a database in the Keystone server. They are, instead, configuration files, and managed via the deployment’s content management system. In a Tripleo based deployment, none of the other services use the policy storage in Keystone, either.

In Tripleo, the deployment of the overcloud is managed via Heat. the OpenStack Tripleo Heat templates have support for deploying files at the end of the install, and this matches how we need to deploy policy.

Tripleo HA Federation Proof-of-Concept

Keystone has supported identity federation for several releases. I have been working on a proof-of-concept integration of identity federation in a TripleO deployment. I was able to successfully login to Horizon via WebSSO, and want to share my notes.

A federation deployment requires changes to the network topology, Keystone, the HTTPD service, and Horizon. The various OpenStack deployment tools will have their own ways of applying these changes. While this proof-of-concept can’t be called production-ready, it does demonstrate that TripleO can support Federation using SAML. From this proof-of-concept, we should be to deduce the necessary steps needed for a production deployment.
