K8s-Migration

Wherein I migrate the last remaining data off of my baremetal Ceph cluster and shut it down. This is part 24 of my k8s migration series. I set up my baremetal Ceph cluster back in March of 2021, driven by how much I liked the idea of large pools of disk I could use to provide S3 storage, Block devices and a POSIX compatible filesystem. Since then, it has served me rather well, and I’ve been using it to provide S3 buckets and volumes for my Nomad cluster. Given how happy I was with it, I also wanted to continue using it for my Kubernetes cluster. ...

Wherein I shut down my Nomad cluster for good. This is part 23 of my k8s migration series. It is finally done, on the 13th of March I shut down my Nomad cluster. I had originally set it up sometime around 2021. The original trigger was that I had started to separate the Docker containers running public-facing services and the purely internal ones. Around that setup, I had constructed a bunch of bash scripts and a couple of shared mounts. It wasn’t pretty, plus the Homelab had recently turned from a utility into a genuine hobby. In short, increased complexity was actually welcomed. 😁 ...

Wherein I replace Uptime Kuma on Nomad with Gatus on Kubernetes. This is part 22 of my k8s migration series. For my service monitoring needs, I’ve been using Uptime Kuma for a couple of years now. Please have a look at the repo’s Readme for a couple of screenshots, I completely forgot to make some before taking my instance down. 🤦 My main use for it was as a platform to monitor the services, not so much as a dashboard. To that end, I gathered Uptime Kuma’s data from the integrated Prometheus exporter and displayed it on my Grafana Homelab dashboard. ...

Wherein I migrate my Mastodon instance to the k8s cluster. This is part 21 of my k8s migration series. Mastodon is currently serving as my presence in the Fediverse. You can find me here, although I’m pretty sure that most of my readers are coming from there already. 😄 If you’re at all interested in joining a genuine community around Homelabbing, I can only recommend to join the fun by following the HomeLab or SelfHosted hashtags and wildly following everyone appearing on there. It’s a great community of rather friendly people enjoying everything from a lonely Pi to several 42U 19" racks full of equipment. If you’re interested in learning more about my own experience with the Fediverse and hosting my own single-user instance, have a look at these older posts. ...

Wherein I migrate my Nextcloud instance to the k8s cluster. This is part 20 of my k8s migration series. Nextcloud is the oldest continuously running service in my Homelab. It started out as an OwnCloud deployment back when I just called my Homelab my “Heimserver”. It ran continuously for more than ten years, and I quite like it. Initially I only used it for file sharing between my devices and as a better alternative to a Samba share. Over the years, I also started using it for contacts and calendar sharing between my phone and desktop as well as sharing of my Firefox bookmarks between my laptop and desktop via Floccus. One perhaps somewhat surprising use case is for backups of OPNsense, which has support for backing up its configuration to Nextcloud out of the box. ...
