# Deploying the Nginx Ingress controller
|
||
|
|
|
||
|
|
This example aims to demonstrate the deployment of an nginx ingress controller and
|
||
|
|
with the use of an annotation in the Ingress rule be able to customize the nginx
|
||
|
|
configuration.
|
||
|
|
|
||
|
|
## 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
|
||
|
|
|
||
|
|
$ kubectl -n kube-system get po
|
||
|
|
NAME READY STATUS RESTARTS AGE
|
||
|
|
default-http-backend-2657704409-qgwdd 1/1 Running 0 28s
|
||
|
|
```
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ kubectl create -f nginx-load-balancer-conf.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
|
||
|
|
```
|
||
|
|
|
||
|
|
## Test
|
||
|
|
|
||
|
|
Check the contents of the annotation is present in the nginx.conf file using:
|
||
|
|
`kubectl exec nginx-ingress-controller-873061567-4n3k2 -n kube-system cat /etc/nginx/nginx.conf`
