  • Home Lab – No More iSCSI: Transfer, Shutdown, and Rebuild

    This post is part of a short series on migrating my home hypervisor off of iSCSI. Observations – Migrating Servers The focus of my hobby time over the few days has been moving production assets to the temporary server. Most of it is fairly vanilla, but I have a few observations worth noting. Let me…

  • Installing Minio on a Synology Diskstation with Nginx SSL

    In an effort to get rid of a virtual machine on my hypervisor, I wanted to move my Minio instance to my Synology. Keeping the storage interface close to the storage container helps with latency and is, well, one less thing I have to worry about in my home lab. There are a few guides…

  • Home Lab – No More iSCSI, Prep and Planning

    This post is part of a short series on migrating my home hypervisor off of iSCSI. I realized today that my home lab setup, by technology standards, is old. Sure, my overall setup has gotten some incremental upgrades, including an SSD cache for the Synology, a new Unifi Security Gateway, and some other new accessories.…

  • Managing Hyper-V VM Startup Times with .Net Minimal APIs

    In a previous post, I had a to-do list that included managing my Hyper-V VMs so that they did not all start at once. I realized today that I never explained what I was able to do or post the code for my solution. So today, you get both. And, for the impatient among you,…

  • Lessons in Managing my Kubernetes Cluster: Man Down!

    I had a bit of a panic this week as routine tasks took me down a rabbit hole in Kubernetes. The more I manage my home lab clusters, the more I realize I do not want to be responsible for bare metal clusters at work. It was a typical upgrade… With ArgoCD in place, the…

  • Hitting for the cycle…

    Well, I may not be hitting for the cycle, but I am certainly cycling Kubernetes nodes like it is my job. The recent OpenSSL security patches got me thinking that I need to cycle my cluster nodes. A Quick Primer In Kubernetes, a “node” is, well, a machine performing some bit of work. It could…

  • What’s in a (Release) Name?

    With Rancher gone, one of my clusters was dedicated to running Argo and my standard cluster tools. Another cluster has now become home for a majority of the monitoring tools, including the Grafana/Loki/Mimir/Tempo stack. That second cluster was running a little hot in terms of memory and CPU. I had 6 machines running what 4-5…

  • A Lesson in Occam’s Razor: Configuring Mimir Ruler with Grafana

    Occam’s Razor posits “Of two competing theories, the simpler explanation is to be preferred.” I believe my high school biology teacher taught the “KISS” method (Keep It Simple, Stupid) to convey a similar principle. As I was trying to get alerts set up in Mimir using the Grafana UI, I came across an issue that…

  • Walking away from Rancher

    I like to keep my home lab running for both hosting sites (like this one) and experimenting on different tools and techniques. It is pretty nice to be able to spin up some containers in a cluster without fear of disturbing other’s work. And, since I do not hold myself to any SLA commitments, it…

  • Kubernetes Observability, Part 5 – Using Mimir for long-term metric storage

    This post is part of a series on observability in Kubernetes clusters: Part 1 – Collecting Logs with Loki Part 2 – Collecting Metrics with Prometheus Part 3 – Dashboards with Grafana Part 4 – Using Linkerd for Service Observability Part 5 – Using Mimir for long-term metric storage (this post) For anyone who actually…
