This example shows how is possible to create a custom configuration for a particular upstream associated with an Ingress rule.
```
echo "
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: echoheaders
annotations:
ingress.kubernetes.io/upstream-fail-timeout: "30"
spec:
rules:
- host: foo.bar.com
http:
paths:
- path: /
backend:
serviceName: echoheaders
servicePort: 80
" | kubectl create -f -
```
Check the annotation is present in the Ingress rule:
```
kubectl get ingress echoheaders -o yaml
```
Check the NGINX configuration is updated using kubectl or the status page:
```
$ kubectl exec nginx-ingress-controller-v1ppm cat /etc/nginx/nginx.conf
```
```
....
upstream default-echoheaders-x-80 {
least_conn;
server 10.2.92.2:8080 max_fails=5 fail_timeout=30;
}
....
```
