## Kubernetes ingress controller


<!-- I had to modify the base ingress to allow for use on 80 and 443. There should be a way to do this with helm, but I can never quite get it to work

this is the original: https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.12.0/deploy/static/provider/baremetal/deploy.yaml

the `ingress-nginx-controller` was changed to a daemonset rather than an deployment
 -->

ingress

```bash
helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update

helm upgrade --install ingress-nginx ingress-nginx/ingress-nginx \
  --namespace ingress-nginx \
  --create-namespace \
  --set controller.kind=DaemonSet \
  --set controller.hostNetwork=true \
  --set controller.service.type=NodePort \
  --set controller.allowSnippetAnnotations=true \
  --set controller.metrics.enabled=false \
  --set controller.ingressClassResource.default=true
```
