Building a light Kubernetes cluster and testing out different scenarios. The plan is to run light and safe (Best Practices). K3s to the rescue!

  • Rancher k8s + k3s (link)
  • Mirantis k0s (link)
  • Portainer (link)
  • k3s and Portainer v2
  • k3up (link)
  • OpenFaaS (link)
  • Longhorn (link)
  • Minikube (link) and LENS (link)
  • Ansible Automation (link) and Ansible Galaxy (link)
  • Continuous Integration (CI) and Continuous Delivery (CD)
  • High Availability (HA)
  • Raspberry Pi [arm64] as EDGE device
  • Zerotier (link) and Remote.it (link) for transparent administration
  • Broadcasting and Radio Automation on EDGE devices
  • Moving towards a cloud-native, microservices-centric future
  • Test Consul & Nomad - a Hashicorp setup as an alternative to Kubernetes. Trying to make things as KISS as possible.

Interesting blogs to read right now:

Also, the question remains to Raspberry Pi Cluster or not?


20 Node Cluster


4 Node Cluster-

Or go all in on ARM: https://amperecomputing.com/altra/

Single socket Ampere Altra processor

Up to 80 cores per processor

2U form factor supported

80-core ARM CPU to bring lower power, higher density to a rack near you
Ampere is competing with Amazon and Nuvia for ARM-powered data-center supremacy.


Check out Jeff Geerling and see how he runs Drupal on Kubernetes using his Rpi Cluster.

Jeff can teach you how to set it up on a Raspberry Pi cluster.

Happy hosting

Currently focusing on building services and providing a low-latency Radio Broadcasting Network in Copenhagen. Doing extensive research, studying, etc. Also, I read a book every day, at least :)
