  1. AZ-103 Study Guide 2020

    I recently passed the AZ-103 Microsoft Azure Administrator Associate. I studied for around six weeks for the exam and in this post I’ll cover all of the resources, systems, and routines I used to study for the exam. Prior to studying for this exam I had very little Azure exposure. I’d blindly click around in the portal before finding information for people, but that’s about it. Studying for this exam was a lot of fun...…


  2. You Are an Engineer Be an Engineer

    Several weeks ago I got some feedback that caused me to pause and reflect. The two lines of feedback were; “I feel you always dig these holes of analysis paralysis and then jump in late.” And “You’re an engineer, go be one.” To add context, these comments were made in a conversation I was having with a friend around how to best dive into Kubernetes. He is someone I look to when learning newer technologies....…


  3. Using Kubernetes Local Persistent Volumes on Docker-Desktop

Because of this, there isn’t an easy way (at least that I’ve found) to access the...…


  4. Deploying Traefik as a Kubernetes Ingress Controller with TLS

    In this blog post I’ll be documenting my several day struggle of figuring out how to deploy Traefik as a Kubernetes ingress controller with TLS. The end result of this article is an ingress controller running in kubernetes cluster on docker-desktop. The Traefik instance will be secured using TLS and will have a redirect rule to point all http traffic to https. Docker-desktop doesn’t have a built-in ingress controller and Traefik is a great open...…


  5. Using Ansible Like PowerShell

    I’ve been using Ansible to manage a Windows environment for a little over a year now and I wanted to share a method of using Ansible that’s helped me adopt it. Coming from a Windows background, I obviously have a strong PowerShell background and to be honest I struggled and still struggle sometimes using Ansible. The reason being, my default behavior is to open up a PowerShell prompt and start hacking away. Skilling up with...…
