Installation des outils
Update the 
apt package index and install packages needed to use the Kubernetes 
apt repository:
sudo apt-get update
sudo apt-get install -y apt-transport-https ca-certificates curl gpg
Download the public signing key for the Kubernetes package repositories. The same signing key is used for all repositories so you can disregard the version in the URL:
curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.29/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg
Note: In releases older than Debian 12 and Ubuntu 22.04, folder 
/etc/apt/keyrings does not exist by default, and it should be created before the curl command.
Add the appropriate Kubernetes 
apt repository. If you want to use Kubernetes version different than v1.29, replace v1.29 with the desired minor version in the command below:
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
Note: To upgrade kubectl to another minor release, you'll need to bump the version in 
/etc/apt/sources.list.d/kubernetes.list before running 
apt-get update and 
apt-get upgrade. This procedure is described in more detail in Changing The Kubernetes Package Repository.
Update 
apt package index, then install kubectl:
sudo apt-get update
sudo apt-get install -y docker.io kubelet kubeadm kubectl kubernetes-cni
containerd config default | sudo tee /etc/containerd/config.toml >/dev/null 2>&1
Edit the file ‘/etc/containerd/config.toml’ and look for the section ‘[plugins.”io.containerd.grpc.v1.cri”.containerd.runtimes.runc.options]’ and change ‘SystemdCgroup = false’ to ‘SystemdCgroup = true‘
$ sudo vi /etc/containerd/config.toml
Save and exit the file.
 
reboot
Initialisation du kube
Sur le noeud 1
kubeadm init
To start interacting with cluster, run following commands on master node,
$ mkdir -p $HOME/.kube
$ sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
$ sudo chown $(id -u):$(id -g) $HOME/.kube/config
Run following kubectl command to get nodes and cluster information,
$ kubectl get nodes
$ kubectl cluster-info
Output of above commands
