HTTPS redirect
Permanently redirect HTTP traffic to HTTPS.
For more information, see the Kubernetes Gateway API documentation.
Before you begin
-
Follow the Get started guide to install K8sGateway, set up a gateway resource, and deploy the httpbin sample app.
-
Get the external address of the gateway and save it in an environment variable.
export INGRESS_GW_ADDRESS=$(kubectl get svc -n gloo-system gloo-proxy-http -o jsonpath="{.status.loadBalancer.ingress[0]['hostname','ip']}") echo $INGRESS_GW_ADDRESS
kubectl port-forward deployment/gloo-proxy-http -n gloo-system 8080:8080
Redirect HTTP traffic to HTTPS
-
Create an HTTP route for the httpbin app that you set up as part of the Get started guide. In the following example, all HTTP requests are redirected to HTTPS, and a 301 HTTP response code is returned to the user.
kubectl apply -f- <<EOF apiVersion: gateway.networking.k8s.io/v1beta1 kind: HTTPRoute metadata: name: httpbin-https-redirect namespace: httpbin labels: example: httpbin-route spec: parentRefs: - name: http namespace: gloo-system hostnames: - redirect.example rules: - filters: - type: RequestRedirect requestRedirect: scheme: https statusCode: 301 EOF
Setting Description spec.parentRefs.name
The name and namespace of the gateway resource that serves the route. In this example, you use the gateway that you installed as part of the Get started guide. spec.hostnames
The hostname for which you want to apply the redirect. spec.rules.filters.type
The type of filter that you want to apply to incoming requests. In this example, the RequestRedirect
is used.spec.rules.filters.requestRedirect.scheme
The type of redirect that you want to apply. The https
scheme redirects all incoming traffic to HTTPS.spec.rules.filters.requestRedirect.statusCode
The HTTP status code that you want to return to the client in case of a redirect. For a permanent redirect, use the 301 HTTP status code. -
Send a request to the httpbin app on the
redirect.example
domain. Verify that you get back a 301 HTTP response code and that your redirect location showshttps://redirect.example:8080/status/200
.curl -vik http://$INGRESS_GW_ADDRESS:8080/status/200 -H "host: redirect.example"
curl -vik localhost:8080/status/200 -H "host: redirect.example"
Example output:
* Mark bundle as not supporting multiuse < HTTP/1.1 301 Moved Permanently HTTP/1.1 301 Moved Permanently < location: https://redirect.example:8080/status/200 location: https://redirect.example:8080/status/200 < date: Mon, 06 Nov 2023 01:48:12 GMT date: Mon, 06 Nov 2023 01:48:12 GMT < server: envoy server: envoy < content-length: 0 content-length: 0
Cleanup
You can remove the resources that you created in this guide.kubectl delete httproute httpbin-https-redirect -n httpbin
