Vagrantfile and Scripts to Automate Kubernetes with Cilium setup using Kubeadm

The purpose of this repo is to create a demo/verification environment for Kubernetes with Cilium on Apple Silicon Macs with Darwin OS. It leverages Vagrant and Parallels as a virtual machine host provider.

This repo is based on the work found in:

Preparation

Install Parallels, Vagrant and the Parallels provider plugin:

% brew install --cask vagrant
...
% vagrant plugin install vagrant-parallels
...
% vagrant plugin list
vagrant-parallels (2.2.5, global)
  - Version Constraint: > 0

The architecture of the solution

The infrastructure that is being deployed consists of:

  • one control-plane node; untainted so it can be use also as a worker
  • two dedicated worker nodes
  • no-kube-proxy Cillium installation

Run it

To invoke the creation of the said infraastructure do

% vagrant up
...

After the successful completion the cluster is accessible as follows:

% export KUBECONFIG=$PWD/config/config
% kubectl get nodes

Install the cilium tools with brew, verify it is operational and connect to the Hubble UI in your browser.

% brew install cilium-cli
% cilium status
