### Deploy nginx-service and expose via nginx-ingress on TCP-port 9000
my-nginx-deployment.yml:
```
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-nginx
spec:
selector:
matchLabels:
run: my-nginx
replicas: 1
template:
metadata:
labels:

```
Apply with `kubectl apply -f my-nginx-deployment.yml`:
```
deployment.apps/my-nginx created
