How to feed a single SPAN/mirror port into more than one OpenShift Virtualization VM, why the obvious options don’t work, and the bridge setting that fixes it. The problem You’ve set up a mirror (SPAN) session on your switch and patched the destination port into a spare NIC on an OpenShift node. You want two...
I’ve been clauding around and shipped a project I’m genuinely proud of: Magic Proxy UBI, a from-scratch container image pairing HAProxy 3.3 (AWS-LC) with the HAProxy Data Plane API on Red Hat UBI10. The backstory: my home lab ran HAProxy bolted onto pfSense for years, routing traffic across a dozen-plus internal apps and a few...
The Problem The Windows Server 2022 Core VM we were working with had a http proxy set but the OpenShift cluster was in an environment that did not need a proxy. Using the top google hits we were unable to clear the “advproxy” settings. C:\> netsh winhttp show proxy Current WinHTTP proxy settings: Direct access...
Getting a Windows Node on OpenShift … Not what this post is about, follow the Red Hat and Microsoft documentation and then consult with your certified Red Hat Solutions Architect or Consultant. Now that I have a windows node <WARNING> Administering a windows node is highly discouraged and will probably result in an unsupported configuration....
OpenShift 4.11 and Windows Containers This feels like a match made in heaven for organizations that are slowly consuming their monoliths or who have decided on Microsoft technologies for their datacenter. Either way, Windows Node support has come a long way in the last 2 years. I must preface this discussion with the assumption that...
Installing vim-console on Windows 2022 from PowerShell Working with Windows Containers has provided me tremendous education. Learning PowerShell has shown me how far the windows realm has come in the form of CLI management. It still seems to be lacking in a few areas, and I really don’t like the extremely verbose syntax nor the...
BASH_HISTORY_FILE or HISTFILE I find myself constantly using multiple terminals on the same system. The default bash history is a good start, but not enough for my needs. After endless searching, testing, ignoring, deleting, and procrastinating I finally found a solution that works for me. Session Isolation I don’t need new history items available across...
I’m starting a new blog focusing on the technology I love and use everyday. Come here to join the adventure. My computer adventure started in the early (19)80’s with the TI-99 and various Tandy Computers. I was the family “Technical Advisor” even though I really only knew just a little more than they did. Fascinated...
I have some “off” brand MiniPC’s that I wanted to add to my home lab. While trying to register them, they all returned the same message. HTTP error (404 - Not Found): Unit with ID “da2cba1f-a856-4a7e-8df0-b6f4101587af” could not be found. I’m not exactly sure, but it seems the bios/efi information is the same across all...
This weekend started like any other. I had grand hopes for getting my home lab in a place I can focus on OpenShift stuff. You know, Install RHV, OpenStack 13, CEPH 3 with RADOS gateway and a few other things. But it wasn’t meant to be. At least I could get RHV installed on my...
Last night I was playing with bonded network interfaces on my personal NAS when my router stopped responding (turns out my Internet provider doesn’t like Jumbo Frames!). I’m using the Tomato by Shibby firmware v136 and was unable to get into the admin console to reset the configuration as my router kept rebooting. After fiddling...
