+# Basic nginx Deployment
+
+## Description
+Here is a basic example a nginx Deployment that can be use for demo and test of Public Cloud Load Balancer.
+Once the Deployment is created your nginx will be internally exposed on port 80 so you can use the ![Basic LB](./basic_lb/lb_base.yaml) in order to forward trafic from LB listener (port 80) to Kubernetes internal nginx (port 80).

+# Install Nginx Ingress Controller on OVHcloud Managed Kubernetes Service
+
+## Description
+
+This documentation explains how to deploy the [Nginx Ingress Controller](https://kubernetes.github.io/ingress-nginx/) on **OVHcloud Managed Kubernetes Service**.  
+The Ingress Controller enables you to expose your HTTP(S) applications running inside the cluster by defining Kubernetes Ingress resources.
+
+---
+
+## Prerequisites
+
+- An existing **OVHcloud Managed Kubernetes cluster** (
+- **kubectl** installed and configured with your cluster credentials.  
+- **Helm** installed ([Installation guide](https://helm.sh/docs/intro/install/)).
+- **Cert-Manager** installed for TLS certificate management ([Documentation](https://cert-manager.io/docs/)).
+
+---
+
+## Installation
+
+1. **Add the Helm repository for ingress-nginx**:
+   ```bash
+   helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
+   helm repo update
+   ```
+
+2. **Deploy Nginx Ingress Controller** in your cluster:
+   ```bash
+   helm upgrade --install ingress-nginx ingress-nginx/ingress-nginx --namespace ingress-nginx --create-namespace --values ./values.yaml
+   ```
+ 3. **Deploy the ClusterIssuer for Cert-Manager**:  
+    Deploy the ClusterIssuer as described on `acme-config.yml` :
+    ```yaml
+    apiVersion: cert-manager.io/v1
+    kind: ClusterIssuer
+    metadata:
+      name: main
+    spec:
+      acme:
+        # The ACME server URL
+        server: https://acme-v02.api.letsencrypt.org/directory
+        # Email address used for ACME registration
+        email: [email protected]
+        # Name of a secret used to store the ACME account private key
+        privateKeySecretRef:
+          name: letsencrypt-prod
+        # Enable the HTTP-01 challenge provider
+        solvers:
+        - http01:
+            ingress:
+              class: nginx
+    ```
+    
+    To do so, apply it using:
+    ```bash
+    kubectl apply -f acme-config.yml
+    ```
+---
+
+## Verification
+
+Check that the Ingress Controller pods are running:
+```bash
+kubectl get pods -n ingress-nginx
+```
+
+Retrieve the **external IP or hostname** automatically provisioned by OVHcloud LoadBalancer:
+```bash
+kubectl get svc ingress-nginx-controller -n ingress-nginx
+```
+
+⚠️ On OVHcloud Managed Kubernetes Service, the LoadBalancer service type automatically provisions an external IP from OVHcloud infrastructure. This IP/hostname must be configured in your DNS records.
+
+---
+
+## Next Steps
+
+1. **Configure your DNS records**:  
+   Point your application’s domain name (e.g. `myapp.example.com`) to the LoadBalancer external IP/hostname obtained in the previous step.
+
+2. **Create an Ingress resource** to route traffic to your application.  
+   Deploy your Ingress using the example `ingress_base.yaml` with TLS using Cert-Manager and Let’s Encrypt:
+   ```yaml
+   apiVersion: networking.k8s.io/v1
+   kind: Ingress
+   metadata:
+     annotations:
+       cert-manager.io/cluster-issuer: "main"
+     name: ngx-deploy-ingress
+   spec:
+     ingressClassName: nginx
+     tls:
+     - hosts:
+       - myapp.example.com
+       secretName: octavia-secret
+     rules:
+     - host: myapp.example.com
+       http:
+         paths:
+         - path: /
+           pathType: Prefix
+           backend:
+             service:
+               name: nginx-deployment
+               port:
+                 number: 80
+   ```
