+# Configuring Ingress
+
+You can make Stratos available via Ingress by following the instructions below.
+
+Ensure that you have Ingress deployed in your Kubernetes environment.
+
+To do this using Helm follow the instructions here: https://github.com/nginxinc/kubernetes-ingress/tree/master/helm-chart.
+
+If you want to use your own certificate, follow the link above for how to do this along with more advanced configuring options.
+
+Briefly, this involves running:
+
+```
+git clone [email protected]:nginxinc/kubernetes-ingress.git
+cd kubernetes-ingress/helm-chart
+helm install --name ingress .
+```
+
+Wait for the Ingress controller pod to be in the Running state.
+
+Now, edit the `ingress.xml` in this folder to suit your needs - most likely you will want to change:
+
+- metadata.namespace to the namespace that you using when deploying Stratos
+
+- spec.rules.host and spec.tls.hosts to change the host from stratos.127.0.0.1.xip.io to suit your deployment
+
+Finally, deploy the Ingress configuraation with:
+
+```
+kubectl apply -f ./ingress.yml
+```
+
+You should now be able to access Stratos via the URL:
+
+```
+https://stratos.127.0.0.1.xip.io
+```
+
+Note if you changed the host in the ingress.yml file, this URL will of course need to be adjusted.
