Since cycling my cluster nodes is a “fire script and wait” operation, I kicked one off today. I ended up running into an issue that required me to dig a bit into ETCD in RKE2, and could not find direct help, so this is as much my own reference as it is a guide for… Continue reading Tech Tip – Interacting with ETCD in Rancher Kubernetes Engine 2

What’s in a home lab?
A colleague asked today about my home lab configuration, and I came to the realization that I have never published a good inventory of the different software and hardware that I run as part of my home lab / home automation setup. While I have documented bits and pieces, I never pushed a full update.… Continue reading What’s in a home lab?
Tech Tip – You should probably lock that up…
I have been running in to some odd issues with ArgoCD not updating some of my charts, despite the Git repository having an updated chart version. As it turns out, my configuration and lack of Chart.lock files seems to have been contributing to this inconsistency. My GitOps Setup I have a few repositories that I… Continue reading Tech Tip – You should probably lock that up…
Rollback saved my blog!
As I was upgrading WordPress from 6.2.2 to 6.3.0, I ran into a spot of trouble. Thankfully, ArgoCD rollback was there to save me. It’s a minor upgrade… I use the Bitnami WordPress chart as the template source for Argo to deploy my blog to one of my Kubernetes clusters. Usually, an upgrade is literally… Continue reading Rollback saved my blog!
When browsers have a mind of their own…
I recently implemented Cloudflare on my domains to allow me some protection on my domains. There were some unintended side effects, and it seems to have to do with my browser’s DNS. Internal Site Management All of my mattgerega.com and mattgerega.org sites are available outside of my network, so putting Cloudflare in front as a… Continue reading When browsers have a mind of their own…
Literally every time I go away…
It really truly seems like every time I go away, something funny happens in the lab and stuff goes down. That pattern continued last week. Loads of Travel A previously planned Jamaican getaway butted up against a short-notice business meeting in Austin. Since I could not get a direct flight to either location, I ended… Continue reading Literally every time I go away…
Speed. I.. am.. Speed.
“One winner, 42 losers. I eat losers for breakfast. Breakfast? Maybe I should have had breakfast. A little brekie could be good for me….”
My quest for speed lead to using 1TB of data every day…
Going Banana
That’s right… just one banana. I have been looking to upgrade the Raspberry PI 3 that has been operating as home lab’s reverse proxy. While it would have been more familiar to find another Raspberry Pi 4 to use, their availability is, well, terrible. I found a workable, potentially more appropriate, solution in the Banana… Continue reading Going Banana
Speeding up Packer Hyper-V Provisioning
I spent a considerable amount of time working through the provisioning scripts for my RKE2 nodes. Each node took between 25-30 minutes to provision. I felt like I could do better. Check the tires A quick evaluation of the process quickly made me realize that most of the time is spent in the full install… Continue reading Speeding up Packer Hyper-V Provisioning
A big mistake and a bit of bad luck…
In the Home Lab, things were going good. Perhaps a little too good. A bonehead mistake on my part and hardware failure combined to make another ridiculous weekend. I am beginning to think this blog is becoming “Matt messed up again.” Permissions are a dangerous thing I wanted to install the Azure DevOps agent on… Continue reading A big mistake and a bit of bad luck…
