# Deploying the Nginx Ingress controller
# Custom configuration
This example aims to demonstrate the deployment of an nginx ingress controller and
use a ConfigMap to configure a custom list of headers to be passed to the upstream
server
## Default Backend
The default backend is a Service capable of handling all url paths and hosts the
nginx controller doesn't understand. This most basic implementation just returns
a 404 page:
```console
$ kubectl apply -f default-backend.yaml
deployment "default-http-backend" created
service "default-http-backend" created
curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/docs/customization/custom-headers/configmap.yaml \
| kubectl apply -f -
$ kubectl -n kube-system get po
NAME READY STATUS RESTARTS AGE
default-http-backend-2657704409-qgwdd 1/1 Running 0 28s
```
curl https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/docs/customization/custom-headers/custom-headers.yaml \
| kubectl apply -f -
## Custom configuration
```console
$ cat nginx-load-balancer-conf.yaml
apiVersion: v1
data:
proxy-set-headers: "default/custom-headers"
kind: ConfigMap
metadata:
name: nginx-load-balancer-conf
```
```console
$ kubectl create -f nginx-load-balancer-conf.yaml
```
## Custom headers
```console
$ cat custom-headers.yaml
apiVersion: v1
data:
X-Different-Name: "true"
X-Request-Start: t=${msec}
X-Using-Nginx-Controller: "true"
kind: ConfigMap
metadata:
name: proxy-headers
namespace: default
```
```console
$ kubectl create -f custom-headers.yaml
```
## Controller
You can deploy the controller as follows:
```console
$ kubectl apply -f nginx-ingress-controller.yaml
deployment "nginx-ingress-controller" created
$ kubectl -n kube-system get po
NAME READY STATUS RESTARTS AGE
default-http-backend-2657704409-qgwdd 1/1 Running 0 2m
nginx-ingress-controller-873061567-4n3k2 1/1 Running 0 42s
```
