Homelab

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. ...

A couple of weeks ago, I migrated my Jellyfin instance to my Kubernetes cluster. This involved copying my approximately 1.7 TB worth of media from the baremetal Ceph cluster to the new Rook Ceph cluster. And I’d like to dig a bit into the metrics and try to read them like the entrails of a slain beast during a full moon at the top of a misty mountain. Just this much, the portents don’t look good for one of my HDDs. ...

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. ...

Wherein I migrate my Jellyfin instance to the k8s cluster. This is part 19 of my k8s migration series. I’m running a Jellyfin instance in my Homelab to play movies and TV shows. I don’t have a very fancy setup, no re-encoding or anything like that. I’m just using Direct Play, as I’m only watching things on my desktop computer. Jellyfin doesn’t have any external dependencies at all, so there’s only the Jellyfin Pod itself to be configured. It also doesn’t have a proper configuration file. Instead, it’s configured through the web UI and a couple of command line options. For that reason, I won’t have any Secrets or ConfigMaps. Instead I’ve just got a PVC with the config and some space for Jellyfin’s cache and another CephFS volume for the media collection. ...

Wherein I migrate several IoT services over to Kubernetes. This is part 18 of my k8s migration series. This is going to be a short one. This weekend, I finished the migration of several IoT related services to k8s. Mosquitto is my MQTT broker, handling messages from several sources. For me, it’s only a listener - I do not have any actual home automations. Said mosquitto instance is scraped by mqtt2prometheus to get the data my smart plugs and thermometers produce into my Prometheus instance. Finally, I also migrated my Zigbee2MQTT instance over to the k8s cluster. It controls my Zigbee transceiver and sends the data from my thermometers on to mosquitto. ...
