Instructions here assume Ubuntu Server 20.04.1 LTS The computers (or virtual machines) must: Alternatively, you can use QEMU to emulate a Raspberry Pi computer. Pre-requisites Raspberry Pi or ARM64 emulatorĪs mentioned before, you can use one or more Rasperry Pi computers. The only downside is that it does not work for Windows, so you need a Linux or MacOS host to kick off the Ansible Playbook.
#MAC EMULATOR ON RASPBERRY PI INSTALL#
I like Ansible for this job because it only requires the nodes to be accessible via SSH with private key authentication - no need to install an agent or anything else on the nodes. Although manually setting up 4 nodes is not the end of the world, I wanted to make the setup as automated as possible.įor those new to Ansible (like me), it automates provisioning and configuration, enabling infrastructure as code.

Eventually I found Rancher’s Ansible Playbook for K3s on how to install it on all nodes with minimal manual configuration. I was aware of Rancher’s K3s Kubernetes but also got to read about Ubuntu’s Microk8s and there is a blog post on how to build a Raspberry Pi cluster with MicroK8s. Next decision was which Kubernetes installation to go with. It can still be automated to some extent but each node needs an unique configuration and each flash card will need to be individually flashed and inserted on the computer. Flashing the OS image and setting up the static IP + hostname + SSH was a manual step. Although no process will address more than 4 GB of RAM, I still want to validate ARM64 images on Dapr. At the time of this writing, the Raspberry Pi OS was only in 32 bits.

An ethernet switch might be needed.įor the operating system, I picked Ubuntu Server 20.04.1 LTS because it was a well known distribution with a 64 bits server (not desktop) version.
This is a “guestimate”, so you can still decide to go with 2GB or 8GB version. Apart from the higher price tag (x4 nodes), the 8GB version seems overkill for this as I guessed that under heavy load (too many pods), the nodes would run hot on CPU utilization before using all the memory. The 2GB version would not give enough memory per node (IMO). I picked the Raspberry Pi 4 with 4GB of RAM since it would give a good memory to CPU ratio: 1x1.5GHz core per GB of RAM. Purchasing the hardware was easy enough, Raspberry Pi would be the go-to solution for a cheap DIY project. For this exercise, I used 4 computers (or nodes).
The setup also must have more than one node, to uncover challenges of provisioning multiple computers. In this case, “from scratch” meant purchasing and provisioning the hardware, in addition to installing Kubernetes. I have used Dapr via Minikube, kind and AKS but I wanted to learn how to setup an on-prem Kubernetes cluster “from scratch” and use Dapr to validate it. In this blog post, I’ll explore how to deploy Dapr on Rancher’s K3s Kubernetes on a cluster of Rasperry Pis, showcasing an example of deployment for edge computing. It is no surprise that Kubernetes is a common hosting environment in this space and we see developers using Dapr in various stages of the development process on Minikube, kind and, of course, on cloud provider services such as Azure Kubernetes Service (AKS). One of the key benefits of Dapr is that it is designed to enable the development of cloud native applications deployed to a variety of environments on the cloud and on the edge.
