sudo apt update && sudo apt upgrade -y

2. Disable Swap sudo swapoff -a sudo sed -i '/ swap / s/^/#/' /etc/fstab free -h

3. Kernel Modules cat «EOF | sudo tee /etc/modules-load.d/k8s.conf overlay br_netfilter EOF sudo modprobe overlay sudo modprobe br_netfilter

4. Sysctl Configuration cat «EOF | sudo tee /etc/sysctl.d/k8s.conf net.bridge.bridge-nf-call-iptables=1 net.bridge.bridge-nf-call-ip6tables=1 net.ipv4.ip_forward=1 EOF sudo sysctl –system

5. Install containerd sudo apt install -y containerd sudo mkdir -p /etc/containerd containerd config default | sudo tee /etc/containerd/config.toml # Edit config: # Set SystemdCgroup = true sudo systemctl restart containerd sudo systemctl enable containerd

6. Install Kubernetes Components sudo apt install -y apt-transport-https ca-certificates curl gpg curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.29/deb/Release.key | \ sudo gpg –dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] \ https://pkgs.k8s.io/core:/stable:/v1.29/deb/ /' | \ sudo tee /etc/apt/sources.list.d/kubernetes.list sudo apt update sudo apt install -y kubelet kubeadm kubectl sudo apt-mark hold kubelet kubeadm kubectl

7. Initialize Control Plane sudo kubeadm init –pod-network-cidr=10.244.0.0/16

8. Configure kubectl mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config kubectl get nodes

9. Install Flannel Network kubectl apply -f https://github.com/flannel-io/flannel/releases/latest/download/kube-flannel.yml kubectl get pods -A

10. Join Worker Nodes sudo kubeadm join <MASTER-IP>:6443 \ –token <TOKEN> \ –discovery-token-ca-cert-hash sha256:<HASH>

11. Verify Cluster kubectl get nodes -o wide

12. Allow Pods on Control Plane (Optional) kubectl taint nodes –all node-role.kubernetes.io/control-plane-

13. Install Metrics Server kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.y kubectl patch deployment metrics-server -n kube-system \ –type='json' \ -p='[{“op”:“add”,“path”:“/spec/template/spec/containers/0/args/-”,“value”:“–kubelet-insecure-tls”}]'

14. Troubleshooting Check pods: kubectl get pods -A Check container runtime: crictl info Ensure CRDs installed before apps like Traefik/MetalLB.
