Much of what I learned about Helm charting and running workloads in Kubernetes I credit to the contributors over at k8s-at-home. There expansive chart collection helped me start to jump in to Kubernetes. Last year, they announced they were deprecating their repositories. I am not surprised: the sheer volume of charts they had meant they… Continue reading Tech Tips – Moving away from k8s-at-home

Bruce Lee to the Rescue! Health Checks for .NET Worker Services
As we start to develop more containers that are being run in Kubernetes, we encounter non-http workloads. I came across a workload that represents a non-http processor for queued events. In .NET, I used the IHostedService offerings to run a simple service in a container to do this work. However, when it came time to… Continue reading Bruce Lee to the Rescue!

Tech Tips – Upgrading your Argo cluster tools
Moving my home lab to GitOps and ArgoCD has been, well, nearly invisible now.

I really want to stay up-to-date when… Continue reading Tech Tips – Upgrading your Argo cluster tools

Tech Tip – Turn on forwarded headers in Nginx
I have been using Nginx as a reverse proxy for some time. In the very first iteration of my home lab, it lived on a VM and allowed me to point my firewall rules to a single target, and then route traffic from there. It has since been promoted to a dedicated Raspberry Pi in… Continue reading Tech Tip – Turn on forwarded headers in Nginx
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… Continue reading Tech Tip – Markdown Linting in VS Code
