Wherein I’m finally done with the backups in my Homelab’s k8s cluster. This is part 15 of my k8s migration series. Finally, I’m done. After months of writing Python code for my backup operator. Especially during the middle phase of the implementation, after the initial planning and design, it felt like a slog. Dozens of tasks, many functions to implement, and seemingly no end in sight. I’m rather elated to finally be able to write another post in the k8s migration series. ...

In the last couple of months, I’ve been working on a k8s operator for running backups of persistent volumes and S3 buckets in my cluster. Previous installments of the series can be found here. And now, I’m finally done with it, and over the weekend, I ran the first successful backups. Time to describe what I’ve implemented, why and how. Recap Let’s start with a recap. For a more detailed description of the problem, have a look at this post in my k8s migration series. ...

I recently randomly wandered onto the Mastodon admin page. What I saw there will shock you. (I’m so sorry about that introduction) That’s perhaps a bit much in the Media storage area for a single user instance. I was pretty sure that I had previously configured Mastodon’s media cache retention to 7 days. Checking up on that, I found that I had remembered correctly. ...

To distract myself from the fact that the last commit in the repo for my k8s Backup Operator was about one month ago, I decided to tackle a random assortment of tasks. One of them was to finally set up link verification for my Blog on Mastodon. It looks like this when it’s working: My Mastodon profile with the link to this blog properly verified, as indicated by the green check mark. ...

I’ve been sitting on this topic since last summer, which was the first one during which I’ve had temperature measurements and history available for my living room. Said living room is also where my Homelab lives, right next to my desk. I’ve never really minded that, but it sitting right next to me most of the time was one factor in deciding to go with low-power Raspberry Pis instead of a couple of Enterprise grade servers. But now I think I discovered a real problem: Heat. ...
