## K8S manifest S6-overlay based images

This YAML configuration defines several Kubernetes resources for deploying and exposing RustDesk, including a ConfigMap for configuration settings, a PersistentVolumeClaim for data storage, a Deployment to manage the application's containers, and two Services for exposing TCP and UDP ports respectively.

### LoadBalancer to expose the service
If you use a bare metal environment to expose the services, use Metallb together with the "metallb.universe.tf/allow-shared-ip" annotations to expose port 21116 in both protocols (UDP and TCP) on the same external ip.

```yaml
apiVersion: v1
kind: Service
metadata:
name: rustdesk-tcp-ports
namespace: rustdesk
annotations:
metallb.universe.tf/allow-shared-ip: "rustdesk-access-port"
spec:
selector:
app: rustdesk-app
ports:
- name: tcp-port-1
port: 21115
targetPort: 21115
- name: tcp-port-2
port: 21116
targetPort: 21116
- name: tcp-port-3
port: 21117
targetPort: 21117
type: LoadBalancer
---
apiVersion: v1
kind: Service
metadata:
name: rustdesk-udp-ports
namespace: rustdesk
annotations:
metallb.universe.tf/allow-shared-ip: "rustdesk-access-port"
spec:
selector:
app: rustdesk-app
ports:
- name: udp-port-1
port: 21116
targetPort: 21116
protocol: UDP
type: LoadBalancer
```
### Persistent Volumes
If you use the manual storageClass type, create a persistent volume before adding the persistentVolumeClaim. The example uses nfs-subdir-external-provisioner StorageClass, but feel free to use it as you see fit.
A manual storageClass example:

```yaml
apiVersion: v1
kind: PersistentVolume
metadata:
name: rustdesk-data-pv
labels:
type: local
spec:
storageClassName: manual
capacity:
storage: 10Gi
accessModes:
- ReadWriteMany
hostPath:
path: '/path/data'
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: rustdesk-data-pvc
namespace: rustdesk
spec:
storageClassName: manual
accessModes:
- ReadWriteMany
resources:
requests:
storage: 10Gi
```
