Sneak preview

It's been a while since our last blog post. We have been crazy busy teaching a course about Microservices, Docker, Kubernetes, etc., using a Kubernetes Raspberry Pi cluster, named KubeCloud.

During this course we have evaluated the use of KubeCloud and how it can help students understand these different concepts. We have a lot of material that we will be sharing after the defense of our thesis at June 20th.

But in the meantime, we have a little treat for you. We couldn't help ourselves, and we had to build something special for our personal clusters.

Kubernetes Logo Shaped Cluster

We like the Kubernetes logo and thought it would be an awesome template for a cluster. See the images below:

What you need to build your own Kubernetes shaped cluster

  • 4pc Raspberry Pi (We used the Raspberry Pi 3 Model B)
  • 4pc 16 GB MicroSDHC cards
  • 1pc Small Switch (We used the d-link go-sw-5e)
  • 4pc 0.3m Ethernet cables (we chose different colors for easy identification)
  • 1pc USB Power Hub (We used Anker PowerPort 6 60W)
  • 4pc Micro-USB cables 0.3m (approx 1ft)

The last thing you need is of course the rack it self. We had it custom made at a laser cutting company. An Illustrator template can be downloaded here.

Once your cluster is assembled, have a look at our previous guide on how to set up Kubernetes-on-ARM.

Stay tuned for more stuff about Kubernetes, Clusters, Raspberry Pis, Microservices, etc.
