A Friend asked me a question about the following piece of music:Continue reading
I started running again last spring. In an effort to spare my knees, I searched for books on good mechanics for the running process, and found the Chi Running Book By Danny Dreyer. I try to keep the mechanics in my head while running to keep myself in good form. Today I started chanting the following in my head while running:Continue reading
When building a strategy for computing, we need to think large scale. I’ve been trying to frame the discussion in terms of a million nodes in a dozen data centers. How is OpenStack going to be able to handle this?Continue reading
In my last post, I went from the Azure Web Portal to the command line. Time to go one step further and use Ansible.Continue reading
While Azure figured prominently in my work about a year ago, I have not had as much to do with it again until recently. I had to relearn everything I had set up last year. As a Keystone and FreeIPA developer, I was focused on identity. Thus, it is somewhat ironic that I had problems getting my head around the identity setup when using Ansible to manage Azure. Here are the steps I went through to go from using the Web Portal to getting Ansible to work. Part one gets through the identity stuff.Continue reading
One of the main reasons for a strategy of “go virtual first” is the ease of checkpointing and restoring key pieces of infrastructure. When running a PXE provisioning system, the PXE server itslef is a piece of key infrastructure, and thus is a viable candidate for running in a Virtual Machine. How did I set up the network to make that possible? macvtap.
OpenStack is Network intensive. The setup I had previously, based around a Juniper Router, did not have enough Ports to reflect a real OpenStack deployment. I decided to forgo GigE speeds and get an older Cicso Catalyst 2960-WS Switch. Here is the new setup.
The tools that we’ve used to develop Keystone have changed a bit over the years. As I work on some long standing bugs, I’ve had to learn what the latest tools are, and how to use them. Recently I had to track down the cause of a failed Tempest run. Here are the steps I went through to find the trace.
