# TLS termination

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

## Prerequisites

You need a TLS cert and a test HTTP service for this example.

## Deployment

Create a `ingress.yaml` file.

    apiVersion: networking.k8s.io/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.

    kubectl apply -f ingress.yaml

## Validation

You can confirm that the Ingress works.

    $ kubectl describe ing nginx-test
    Name:           nginx-test
    Namespace:      default
    Address:        104.198.183.6
