Discontinued A Kubernetes Controller for the Pimoroni Blinkt on a Raspberry Pi
Similarly, fluentd is much more like NoSQL as a datastore than anything else. Prometheus is fundamentally a TSDB, and Loki is moving that direction (it's currently boltdb, which is also just a k:v store).
Then I decided to create a project, Raspberry PI Cluster to share my Ansible source code and installation guides, so others could build their own cluster for learning purposes or selfhosting their own applications.
In fact, manual instructions to deploy the kubernetes basic services can be used, for learning/testing purposes, in single node environment using k3d, a lightweight dockerized version of k3s. All services, except Longhorn, could be deployed and tested using k3d.
Have almost the exact same setup as you down to the same Ethernet cables. I just added a blinkt led light kit to each PI and I’m using blinkt k8s controller to show the state of pods.
