+TCP and UDP services for deployment in Kubernetes to explore ingress
+
+## Deployment
+```bash
+kubectl apply -f tcp-server-ss.yaml
+kubectl apply -f udp-server-ss.yaml
+```
+
+## Minikube nginx ingress controller
+
+Create ingress-nginx-controller-patch.yaml
+```yaml
+spec:
+  template:
+    spec:
+      containers:
+      - name: controller
+        ports:
+         - containerPort: 5000
+           hostPort: 5000
+           protocol: UDP
+         - containerPort: 5001
+           hostPort: 5001
+
+```
+
+Configure ingress
+```bash
+kubectl patch configmap udp-services -n ingress-nginx --patch '{"data":{"5000":"default/udp-server-0-service:5000"}}'
+kubectl patch configmap tcp-services -n ingress-nginx --patch '{"data":{"5001":"default/tcp-server-0-service:5001"}}'
+kubectl patch deployment ingress-nginx-controller -n ingress-nginx --patch "$(cat ingress-nginx-controller-patch.yaml)" -n ingress-nginx
+```
+
+Reach services on minikube ip (e.g. 192.168.49.2)
+
+## K3S With Traefic
+
+- On K3S master, create file `/var/lib/rancher/k3s/server/manifests/traefik-config.yaml` with additional ports to expose. See example in traefik directory
+
+- Create instances of IngressRouteTCP or IngressRouteUDP as needed
+```bash
+kubectl apply -f ingressRouteTcp.yaml
+kubectl apply -f ingressRouteUdp.yaml
+```
+
+- Services should be available; check details from the `traefik` service in the `kube-system` namespace, as they may be on a load balancer IP if something like `metallb` is in use.
