+Since the development has been realised in a K3S environment, we will use the lightweight solution provided by **traefik**. 
+
+We need to install **metallb** to expose our cluster to the exterior and allow packets to reach traefik.
+
+### Deploy traefik and metallb
+
+- Make sure that helm is installed, else visit : https://helm.sh/docs/intro/install/ 
+
+- Add the repositories for traefik and metallb
+> helm repo add metallb https://metallb.github.io/metallb 
+> helm repo add traefik https://helm.traefik.io/traefik
+
+>helm repo update
+
+- Create the namespaces for each
+> kubectl create ns traefik-ingress
+> kubectl create ns metallb-system 
+
+- Configure the deployment 
+
+```
+cat > traefik-values.yaml <<EOF

+- Launch the installs
+> helm upgrade --install metallb metallb/metallb
+> helm upgrade --install metallb metallb/metallb
