# TLS termination

This example demonstrates how to terminate TLS through the nginx Ingress controller.

## Prerequisites

You need a [TLS cert](../PREREQUISITES.md#tls-certificates) and a [test HTTP service](../PREREQUISITES.md#test-http-service) for this example.

## Deployment

Create a `values.yaml` file.

```yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx-test
spec:
  tls:
    - hosts:
      - foo.bar.com
      # This assumes tls-secret exists and the SSL 
      # certificate contains a CN for foo.bar.com
      secretName: tls-secret
  rules:
    - host: foo.bar.com
      http:
        paths:
        - path: /
          backend:
            # This assumes http-svc exists and routes to healthy endpoints
            serviceName: http-svc
            servicePort: 80
```

The following command instructs the controller to terminate traffic using the provided 
TLS cert, and forward un-encrypted HTTP traffic to the test HTTP service.

```console
kubectl apply -f ingress.yaml
```

## Validation

You can confirm that the Ingress works.

```console
$ kubectl describe ing nginx-test
Name:			nginx-test

Address:		104.198.183.6
Default backend:	default-http-backend:80 (10.180.0.4:8080,10.240.0.2:8080)
