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
