  • MMM-PrometheusAlerts: Display Alerts in Magic Mirror

    I have had MagicMirror running for about a year now, and I love having it in my office. A quick glance gives my family and I a look at information that is relevant for the days ahead. As I continue my dive into Prometheus for monitoring, it occurred to me that I might be able…

  • Tech Tips – Upgrading your Argo cluster tools

    Moving my home lab to GitOps and ArgoCD has been, well, nearly invisible now. With the build pipelines I have in place, I’m able to work on my home projects without much thought to deploying changes to my clusters. My OCD, however, prevents me from running old versions. I really want to stay up-to-date when…

  • Creating a simple Nginx-based web server image

    One of the hardest parts of blogging is identifying topics. I sometimes struggle with identifying things that I have done that would be interesting or helpful to others. In trying to establish a “rule of thumb” for such decisions, I think things that I have done at least twice qualify as potential topics. As it…

  • Nginx Reverse proxy: A slash makes all the difference.

    I have been doing some work to build up some standard processes for Kubernetes. ArgoCD has become a big part of that, as it allows us to declaratively manage the state of our clusters. After recovering from a small blow-up in the home lab (post coming), I wanted to migrate my cluster tools to utilize…

  • Tech Tip – Azure DevOps Pipelines Newline handling

    Just a quick note: It would seem that somewhere between Friday, April 29, 2022 and Monday, May 2, 2022, Azure DevOps pipelines changed their handling of newlines in YAML literal blocks. The change caused our pipelines to stop executing with the following error: What caused it? Multi-line, inline block definitions.

  • The trip to Windows 11

    The past five weeks have been a blur. Spring soccer is in full swing, and my time at the keyboard has been limited to mostly work. A PC upgrade at work started a trickle-down upgrade, and with things starting to settle it’s probably worth a few notes. Swapping out the work laptop My old work…

  • Tech Tip – Markdown Linting in VS Code

    With a push to driving better documentation, it is worth remembering that Visual Studio Code has a variety of extensions that can help with linting/formatting of all types of files, including your README.md files. Markdown All in One and markdownlint are my current extensions of choice, and they have helped me clean up my README.md…

  • Not everything you read on the internet is true….

    I spend a lot of time searching the web for tutorials, walkthroughs, and examples. So much so, in fact, that “Google Search” could be listed as a top skill on my resume. With that in mind, though, it’s important to remember that not everything you read on the Internet is true, and to take care…

  • Can Yellowstone teach us about IT infrastructure management?

    It seems almost too fitting that, at a time when the popularity of gritty television like Yellowstone and 1883 is climbing, that I write to encourage you to stop taking on new pets and to start running a cattle ranch. Pet versus Cattle – The IT Version The “pet versus cattle” analogy is often used…

  • A little open source contribution

    The last month has been chock full of things I cannot really post about publicly, namely, performance reviews and security remediations. And while the work front has not been kind to public posts, I have taken some time to contribute back a bit more to the Magic Mirror project. Making ToDo Better Thomas Bachmann created…
