or How I Learned to Love the Lack of Environment Variables Previously I posted a preview of my favorite new feature of OpenStackClient, support for cloud configuration files and the new --os-cloud global option. Who knew it would take six months to get it done and released? There is some merely adequate documentation of the Client Cloud Configuration (or CCC) operation in the OSC Configuration docs, but this is too good to leave to official docs alone. CCC was actually introduced in OSC release 1.1.0, which is the basis for compatibility with Liberty dependency requirements. But like the rest of

I was looking forward to writing a bit about OpenStackClient becoming the first project added to OpenStack under the 'big yurt' [1] governance model. It was even mostly written and set to publish right after the QA Code sprint article when Nebula did what so many startups do, which is to abruptly cease to exist. On April 1 no less. So instead I'll rehash this as a note on OSC's third birthday, based on the first repo commit. Looking Backward I don't want to spend too much energy looking at where we have been, except to note that a lot

OpenStackClient has had plugin support for a while now and it is being used by real-world OpenStack project clients such as Congress. I've also been using it as an entry point (ha!) for some of my experimental command setups, and so can you. osc-debug I've spent a lot of time debugging OSC lately in preparation for my favorite new feature yet-to-come, support for the new --os-cloud option that takes advantage of os-client-config's cloud configuration file abilities. Much of this debugging is necessarily around authentication and it became obvious to me that a built-in way to see what OSC was using

One of the coolest (IMHO) new features [1] recently added to OpenStackClient is its leveraging of a new-ish feature of Keystone's client library, authentication plugins. As that name implies, this allows for Keystone client to be able to use an extendable set of authentication backends for validating users. At press time (keypress time for the pedantic) the freshly released python-keystoneclient 0.11.2 includes the traditional password method, a new variant on the token method and a recent addition supporting SAML2. Happily, the master branch of OpenStackClient has learned how to take advantage of these plugins, plus any additional ones written for

OpenStackClient (OSC) has been in my project queue for almost two years now. It was Feb 2012 that I stayed up all night mucking about with something called DrStack with the goal of combining the then four OpenStack CLI binaries into a single command set. OSC is the second major realization of that goal having a greatly improved internal command architecture courtesy of dhellmann's Cliff framework. It also somehow got an informal blessing without becoming an official project, a status that it still carries. We have a roadmap of where to go with that but that is a topic for
