    Share on: twitter facebook linkedin copy

    It's super handy when a Linux config file is loaded with comments to tell you precisely how to configure the thing, but all those comments can really get in the way when you're trying to review the current configuration. Next time, instead of scrolling through page after page of lengthy embedded explanations, just use: …

    Create Virtual Machines on a Chromebook with HashiCorp Vagrant

    I've lately been trying to do more with Salt at work, but I'm still very much a novice with that tool. I thought it would be great to have a nice little portable lab environment where I could deploy a few lightweight VMs and practice managing them with Salt - without impacting any systems that are actually being used …

    Tailscale golink: Private Shortlinks for your Tailnet

    I've shared in the past about how I use custom search engines in Chrome as quick web shortcuts. And I may have mentioned my love for Tailscale a time or two as well. Well I recently learned of a way to combine these two passions: Tailscale golink. The golink announcement post on the Tailscale blog offers a great …

    Tailscale on VMware Photon OS

    You might remember that I'm a pretty big fan of Tailscale, which makes it easy to connect your various devices together in a secure tailnet, or private network. Tailscale is super simple to set up on most platforms, but you'll need to install it manually if there isn't a prebuilt package for your system. Here's a …

    K8s on vSphere: Building a Kubernetes Node Template With Packer

    I've been leveraging the open-source Tanzu Community Edition Kubernetes distribution for a little while now, both in my home lab and at work, so I was disappointed to learn that VMware was abandoning the project. TCE had been a pretty good fit for my needs, and now I needed to search for a replacement. VMware is …

    You may have heard that there's a new vSphere release out in the wild - vSphere 8, which just reached Initial Availability this week. Upgrading the vCenter in my single-host homelab is a very straightforward task, and using the included Lifecycle Manager would make quick work of patching a cluster of hosts... but …

    Using the vSphere Diagnostic Tool Fling

    VMware vCenter does wonders for abstracting away the layers of complexity involved in managing a large virtual infrastructure, but when something goes wrong it can be challenging to find exactly where the problem lies. And it can be even harder to proactively address potential issues before they occur. Fortunately …

    Removing and Recreating vCLS VMs

    Way back in 2020, VMware released vSphere 7 Update 1 and introduced the new vSphere Clustering Services (vCLS) to improve how cluster services like the Distributed Resource Scheduler (DRS) operate. vCLS deploys lightweight agent VMs directly on the cluster being managed, and those VMs provide a decoupled and …

    I've been doing a bit of work lately to make my vRealize Automation setup more flexible and dynamic and less dependent upon hardcoded values. To that end, I thought it was probably about time to learn how to interact with the vRA REST API. I wrote this post to share what I've learned and give a quick crash course on …

    Active Directory authentication in Tanzu Community Edition

    Not long ago, I deployed a Tanzu Community Edition Kubernetes cluster in my homelab, and then I fumbled through figuring out how to log into it from a different device than the one I'd used for deploying the cluster from the tanzu cli. That setup works great for playing with Kubernetes in my homelab but I'd love to do …

    Now that VMware has released vCenter 7.0U3c to resolve the Log4Shell vulnerabilities I thought it might be fun to run a security scan against the upgraded VCSA in my homelab to see how it looks. Of course, I don't actually have a security scanner in that environment so I'll need to deploy one. I start off by heading to …
