# NGINX Ingress running in AWS
|
||||||
|
|
||||||
|
This example shows how is possible to use the nginx ingress controller in AWS behind an ELB configured with Proxy Protocol.
|
||||||
|
|
||||||
|
```console
|
||||||
|
kubectl create -f ./nginx-ingress-controller.yaml
|
||||||
|
```
|
||||||
|
|
||||||
|
This command creates:
|
||||||
|
- a default backend deployment and service.
|
||||||
|
- a service with `type: LoadBalancer` configuring Proxy Protocol in the ELB (`service.beta.kubernetes.io/aws-load-balancer-proxy-protocol: '*'`).
|
||||||
|
- a configmap for the ingress controller enabling proxy protocol in NGINX (`use-proxy-protocol: "true"`)
|
||||||
|
- a deployment for the ingress controller
|
||||||
|
|
||||||
|
Is the proxy protocol necessary?
|
||||||
|
|
||||||
|
No but only enabling the procotol is possible to keep the real source IP address requesting the connection.
