In addition, you can redirect HTTP connections to HTTPS.\n\nHTTPS creates a secure channel over an insecure network, protecting against man-in-the-middle attacks and encrypting traffic between the client and server. To prepare a web server to accept HTTPS connections, an administrator must create a public key certificate for the server. This certificate must be signed by a trusted certificate authority for a web browser to accept it without warning.\n| **Note:** These instructions supplement the Istio instructions to [configure a TLS ingress gateway](https://istio.io/latest/docs/tasks/traffic-management/ingress/secure-ingress), and assume that a valid certificate and private key for the server have already been created.\n\nEdit the gateway named external-gateway in the `kf` namespace using the built-in Kubernetes editor: \n\n```\nkubectl edit gateway -n kf external-gateway\n```\n\n1. Assuming you have a certificate and key for your service, create a Kubernetes secret for the ingress gateway. Make sure the secret name does not begin with `istio` or `prometheus`. For this example, the secret is named `myapp-https-credential`.\n2. Under `servers:`\n 1. Add a section for port 443.\n 2. Under `tls:`, set the `credentialName` to the name of the secret you just created.\n 3. Under `hosts:`, add the host name of the service you want to secure with HTTPS. This can be set to an entire domain using a wildcard (e.g. `*.example.com`) or scoped to just one hostname (e.g. `myapp.example.com`).\n3. There should already be a section under `servers:` for port 80 HTTP. Keep this section in the Gateway definition if you would like all traffic to come in as HTTP.\n4. To redirect HTTP to HTTPS, add the value `httpsRedirect: true` under `tls` in the HTTP server section. See the [Istio Gateway documentation](https://istio.io/latest/docs/reference/config/networking/gateway/) for reference. Note that adding this in the section where `hosts` is set to `*` means that **all** traffic is redirected to HTTPS. If you only want to redirect HTTP to HTTPS for a single app/domain, add a separate HTTP section specifying the redirect.\n\nShown below is an example of a Gateway `spec` that sets up HTTPS for `myapp.example.com` and redirects HTTP to HTTPS for that host: \n\n spec:\n selector:\n istio: ingressgateway\n servers:\n - hosts:\n - myapp.example.com\n port:\n name: https\n number: 443\n protocol: HTTPS\n tls:\n credentialName: myapp-https-credential\n mode: SIMPLE\n - hosts:\n - myapp.example.com\n port:\n name: http-my-app\n number: 80\n protocol: HTTP\n tls:\n httpsRedirect: true\n - hosts:\n - '*'\n port:\n name: http\n number: 80\n protocol: HTTP"]]
