+
+# Description
+
+This example adds `HTTP` to `HTTPS` redirect at the port `80` of the gateway, which listens for HTTP traffic.
+
+Also contains a listens for `HTTPS` traffic at the port 443, with a self-signed certificate. This will be used to ensure that the redirect is working correctly.
+
+
+> **NOTE:**\
+> This example is kept at minimal, without the need of containing a `Virtual Service`, a `Service` nor a `Deployment/Pod`.
+
+# Configuration applied
+
+## Gateway
+
+The port `80` listens for any host, expecting `HTTP` traffic.\
+As `tls.httpsRedirect` is set to `true`, the incoming traffic will be redirected to `HTTPS`, effectively enabling the `HTTP` to `HTTPS` redirect.
+
+
+The port `443` is expecting traffic that use the `HTTPS` protocol, without being limited to specific hosts.\
+The TLS configuration is set to simple, and the credentials (the object that contains the certificates/TLS configuration) is set to `my-tls-cert-secret`.
+
+```yaml
+apiVersion: networking.istio.io/v1alpha3
+kind: Gateway
+metadata:
+  name: helloworld-gateway
+spec:
+  selector:
+    istio: ingressgateway
+  servers:
+    - port:
+        number: 80
+        name: http
+        protocol: HTTP
+      hosts:
+        - "*"
+      tls:
+        httpsRedirect: true
+    - port:
+        number: 443
+        name: https-web
+        protocol: HTTPS
+      hosts:
+        - "*"
+      tls:
+        mode: SIMPLE
+        credentialName: my-tls-cert-secret
+```
+
+> **Note:**\
+> The credentials resource is created further bellow through the [Walkthrough](#walkthrough) steps.
+
+> **Note:**\
+> For more information regarding the TLS mode configuration, refer to the following [Istio documentation regarding the TLS mode field](https://istio.io/latest/docs/reference/config/networking/gateway/#ServerTLSSettings-TLSmode).
+
+# Walkthrough
+
+## Generate client and server certificate and key files
+
+First step will be to generate the certificate and key files to be able to set them to the Gateway resource.
+
+### Create a folder to store files.
+
+Create the folder to contain the files that will be generated. 
+
+```shell
+mkdir certfolder
+```
+
+### Create a certificate and a private key.
+
+```shell
+openssl req -x509 -sha256 -nodes -days 365 -subj '/O=Internet of things/CN=lb.net' -newkey rsa:2048 -keyout certfolder/istio.cert.key -out certfolder/istio.cert.crt
+```
+
+The files generated are the following:
+
+```yaml
+private-key: certfolder/istio.cert.key
+root-certificate: certfolder/istio.cert.crt
+```
+
+The information set to the certificate generated is the following:
+
+```yaml
+Organization-name: Internet of things
+CN: lb.net
+```
+
+### Create a TLS secret
+
+At this step we create the tls secret `my-tls-cert-secret` on the namespace `istio-system`.
+
+```shell
+kubectl create -n istio-system secret tls my-tls-cert-secret \
+  --key=certfolder/istio.cert.key \
+  --cert=certfolder/istio.cert.crt
+```
+```text
+secret/my-tls-cert-secret created
+```
+```text
+service/helloworld created
+deployment.apps/helloworld-nginx created
+gateway.networking.istio.io/helloworld-gateway created
+virtualservice.networking.istio.io/helloworld-vs created
+```
+
+> **Note:**\
+> It's Important that the secret is located in the same namespace as the Load Balancer used. In my case is the `istio-system`, but it will vary based on the environment.
+
+
+## Deploy resources
+
+```shell
+kubectl apply -f ./
+```
+```text
+gateway.networking.istio.io/helloworld-gateway created
+```
+
+## Test the service
+
+### Curl --HEAD
+
+We receive the status message `301 Moved Permanently`.
+
+This points that we are being redirected somewhere. By default, `curl` doesn't follow the redirects. 
+
+To confirm the redirect is being performed towards the `HTTPS` service, we allow `curl` to follow redirects.
+
+```shell
+curl  http://192.168.1.50 -I
+```
+```text
+HTTP/1.1 301 Moved Permanently
+location: https://192.168.1.50/
+date: Tue, 25 Apr 2023 23:59:34 GMT
+server: istio-envoy
+transfer-encoding: chunked
+```
+
+### Curl --HEAD follow redirects
+
+Allowing `curl` to follow redirects, we notice the following output:
+
+- First we receive the same message from before, as we connected to the same service.
+
+- Afterwards we are met with a status code `404`, which is expected as we don't have any service configured behind this gateway.
+
+> **NOTE:**\
+> Due using a self-signed certificate, had to allow accessing "insecure" `HTTPS` destinations.  
+
+```shell
+curl  http://192.168.1.50 -I -L -k
+```
+```text
+HTTP/1.1 301 Moved Permanently
+location: https://192.168.1.50/
+date: Wed, 26 Apr 2023 00:05:24 GMT
+server: istio-envoy
+transfer-encoding: chunked
+
+HTTP/2 404 
+date: Wed, 26 Apr 2023 00:05:24 GMT
+server: istio-envoy
+```
+
+## Cleanup
+
+```shell
+kubectl delete -n istio-system secret my-tls-cert-secret
+```
+
+```text
+secret "my-tls-cert-secret" deleted
+```
+
+```shell
+kubectl delete -f ./
+```
+```text
+gateway.networking.istio.io "helloworld-gateway" deleted
+```
+
+```shell
+rm -rv certfolder/
+```
+
+```text
+removed 'certfolder/istio.cert.key'
+removed 'certfolder/istio.cert.crt'
+removed directory 'certfolder/'
+```
