+# Containerd and Kubernetes Installation Guide
+
+## 1. Disable Swap
+Turn off swap and disable it permanently.
+
+```bash
+swapoff -a
+sed -i '/swap/d' /etc/fstab
+```
+## 2. Enable Required Kernel Modules
+Create a configuration file to load necessary kernel modules and load them temporarily.
+```bash
+echo -e "overlay\nbr_netfilter" | sudo tee /etc/modules-load.d/containerd.conf
+sudo modprobe overlay
+sudo modprobe br_netfilter
+```
+## 3. Enable IPv4 Forwarding
+Enable IPv4 forwarding in the sysctl configuration and apply the changes.
+```bash
+sed -i 's/#net.ipv4.ip_forward=1/net.ipv4.ip_forward=1/' /etc/sysctl.conf
+sysctl -p
+```
+## 4. Configure Containerd
+Generate the default configuration for Containerd and modify it to use systemd as the cgroup driver.
+```bash
+containerd config default | sudo tee /etc/containerd/config.toml
+sudo sed -i 's/SystemdCgroup = false/SystemdCgroup = true/' /etc/containerd/config.toml
+```
+
+## 5. Install Kubernetes
+Add the Kubernetes package repository and install the required packages.
+```bash
+sudo mkdir -p /etc/apt/keyrings
+curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.30/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:/v1.30/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list
+sudo apt-get update
+sudo apt-get install -y kubelet kubeadm kubectl
+sudo apt-mark hold kubelet kubeadm kubectl
+```
+## 6. Enable kubelet
+Enable and start the kubelet service.
+```bash
+sudo systemctl enable --now kubelet
+```
+## 7. Initialize the Kubernetes Cluster
+Initialize the Kubernetes control plane with the specified parameters.
+```bash
+sudo kubeadm init --control-plane-endpoint 192.168.2.100 --apiserver-advertise-address 192.168.2.100 --pod-network-cidr 10.244.0.0/16 | tee kuber-install.log
+```
+## 8. Create Control Plane Join Command
+Create the control plane join command and save it for later use.
+```bash
+sudo kubeadm init phase upload-certs --upload-certs
+
+Copy the output certificate key and run the following command, replacing <CERTIFICATE_KEY> with the copied key.
+
+sudo kubeadm token create --certificate-key <CERTIFICATE_KEY> --print-join-command | tee cp-command.txt
+```
+## 9. Join Control Plane and Worker Nodes
+Use the command from cp-command.txt on your control plane nodes to join them. Additionally, get the join command for worker nodes from kuber-install.log and run it on each worker node.
