In the last post of my Backup Operator series, I lamented the state of permissions in the kopf Kubernetes Operator framework. After some thinking, I decided to go ahead with kopf and just accept the permission/RBAC ugliness. I’ve just finished implementing the first cluster state change in the operator, so I thought this is a good place to write a post about my approach and setup. The journey up to now has been pretty interesting....

As I’ve mentioned in my last k8s migration post, I’m working on writing a Homelab backup operator for my Kubernetes cluster. And I’ve run into some RBAC/permission issues I can’t quite figure out. So let’s see whether writing about it helps. 🙂 First, a short overview of the plan. I’m using the kopf framework to build a Kubernetes operator. This operator’s main goal is to handle HomelabServiceBackup resources. These will contain a list of PersitentVolumeClaims and S3 buckets which need to be backed up....

Wherein it seems I need a new backup strategy. This is part 13 of my k8s migration series. During the last week, I’ve started to work on implementing my backup strategy for the new Kubernetes cluster. The original plan was to stay with what I’m already doing in my Nomad cluster. But it turns out I can’t, so I need a new strategy. If you’re prone to suffering from IT-related nightmares, you might wish to skip this one....

Wherein I migrate my internal container registry to Harbor. This is part 12 of my k8s migration series. Let’s start by answering the obvious question: Why even have an internal container registry? For me, there are two reasons: Some place to put my own container images A cache for external images Most of my internal images are slightly changed external images. A prime example is my Fluentd image. I’ve extended the official image with a couple of additional plugins....

Wherein I migrate my Grafana instance over to k8s. This is part 11 of my k8s migration series. I already wrote about my love for metrics in the companion post about the Prometheus setup, so I will spare you my excitement about pretty graphs this time. 😉 For the Grafana setup, I used the kube-prometheus-stack’s integration of the Grafana Helm Chart. Database setup First step is to setup the database for Grafana....
