Local setup using Vagrant

After some time of teetering trial and error, I managed to run a properly configured cluster using vagrant.
Vagrantfile
- Vagrant.configure("2") do |config|
- # Define common settings for both VMs
- config.vm.box = "ubuntu/focal64" # Ubuntu 20.04
- config.vm.provider "virtualbox" do |vb|
- vb.memory = "8192"
- vb.cpus = 2
- end
- # Control Plane Node
- config.vm.define "cp-node" do |cp|
- cp.vm.hostname = "cp-node"
- cp.vm.network "private_network", type: "static", ip: "192.168.56.10"
- cp.vm.provider "virtualbox" do |vb|
- end
- cp.vm.provision "shell", inline: <<-SHELL
- sudo swapoff -a
- sudo sed -i '/ swap / s/^/#/' /etc/fstab
- sudo systemctl disable --now ufw
- sudo systemctl stop apparmor
- sudo systemctl disable --now apparmor
- SHELL
- end
- # Worker Node
- config.vm.define "worker-node" do |worker|
- worker.vm.hostname = "worker-node"
- worker.vm.network "private_network", type: "static", ip: "192.168.56.11"
- worker.vm.provision "shell", inline: <<-SHELL
- sudo swapoff -a
- sudo sed -i '/ swap / s/^/#/' /etc/fstab
- sudo systemctl disable --now ufw
- sudo systemctl stop apparmor
- sudo systemctl disable --now apparmor
- SHELL
- end
- end
- start the machines
- vagrant up
- populate the /etc/hosts file of each node with the ip addresses of both nodes:
- echo -e "192.168.56.10 cp-node\n192.168.56.11 worker-node" | sudo tee -a /etc/hosts
download the resources from the cm.lf.training(LFD259_V2024-09-20_SOLUTIONS) site on both nodes
cp-node: modify the k8scp.sh script script and execute it:
bash cp $(find $HOME -name k8scp.sh) . && sed -i 's|sudo kubeadm init --kubernetes-version=1.31.1 --pod-network-cidr=10.0.0.0/8|sudo kubeadm init --apiserver-advertise-address=192.168.56.10 --pod-network-cidr=10.200.0.0/16|' k8scp.sh && sed -i 's|cilium install --version 1.16.1*|cilium install --version 1.16.1 --set ipam.operator.clusterPoolIPv4PodCIDRList=10.200.0.0/16|' k8scp.sh &&bash k8scp.sh | tee $HOME/cp.out
worker-node: modify the k8Worker.sh script and execute it :bash cp $(find $HOME -name k8sWorker.sh) . && bash k8sWorker.sh | tee worker.out
- worker-node: Then just use the join command as per the instructions. And that should be it
I hope it helps
