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.
Spent a good chunk of yesterday and some of this morning stumped by a simple mistake I made. I was trying to use our Satellite server via the Hammer command line tool to launch an instance, and kept getting and error in the content-view section. I tried to list content views and got the same problem. Here is a short section from my bash session.
Today is my first day at Red Hat! Well, OK, I’ve been here a few years, but today I move from Engineering to Sales. My new role is “Specialist Solutions Architect” where that specialty is Cloud.
I have a lot to learn, and I will try to use this site to record the most important and interesting details I learn.
What are the Cloud Products? well, according to Red Hat’s site, they are (please mentally prepend Red Hat to all of these) OpenStack Platform, OpenShift, CloudForms, Virtualization, Certificate System, Directory Server, as well as products bundles built out of these. Of these all, I’d guess I have the most to learn about CloudForms, as I’ve only recently started working with that. Really, though, I have a lot to learn across the board. I know that both Ansible Tower and Satellite server are major integration points for management of servers in the large, and I’ll be expected to provide expertise there as well. Plus, everything builds on the other product lines: RHEL and variants, as well as the Storage and Networking solutions.
This is going to be fun. Time to dig in.
