+# Beszel Hub Helm Chart
+
+A Kubernetes Helm chart for deploying [Beszel Hub](https://www.beszel.dev/) - a monitoring and alerting solution for systems, containers, and services.
+
+## Overview
+
+This Helm chart simplifies the deployment of Beszel Hub in Kubernetes environments. Beszel Hub is a centralized monitoring hub that collects and aggregates system metrics from multiple agents deployed across your infrastructure.
+
+## Prerequisites
+
+- Kubernetes 1.19+
+- Helm 3.0+
+- At least 500Mi of persistent storage (configurable)
+
+## Quick Start
+
+### 1. Add the Repository
+
+```bash
+helm repo add beszel https://henrygd.github.io/beszel
+helm repo update
+```
+
+### 2. Install the Chart
+
+```bash
+helm install beszel-hub ./beszel-hub
+```
+
+Or with a custom values file:
+
+```bash
+helm install beszel-hub ./beszel-hub -f custom-values.yaml
+```
+
+### 3. Access Beszel Hub
+
+By default, Beszel Hub is accessible at `http://beszel-hub:8090` within the cluster.
+
+```bash
+# Port forward to access locally
+kubectl port-forward svc/beszel-hub 8090:8090
+```
+
+Then visit: `http://localhost:8090`
+
+## Configuration
+
+### Basic Configuration
+
+Key configuration options in `values.yaml`:
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `replicaCount` | `1` | Number of Beszel Hub replicas |
+| `image.repository` | `henrygd/beszel` | Container image repository |
+| `image.tag` | Chart AppVersion (0.17.0) | Container image tag |
+| `image.pullPolicy` | `IfNotPresent` | Image pull policy |
+| `service.port` | `8090` | Service port |
+| `persistentVolumeClaim.enabled` | `true` | Enable persistent volume |
+| `persistentVolumeClaim.size` | `500Mi` | PVC size |
+
+### Installation with Custom Values
+
+```bash
+helm install beszel-hub ./beszel-hub \
+  --set replicaCount=2 \
+  --set persistentVolumeClaim.size=1Gi \
+  --set service.type=LoadBalancer
+```
+
+Or create a custom values file:
+
+```yaml
+# custom-values.yaml
+replicaCount: 2
+service:
+  type: LoadBalancer
+persistentVolumeClaim:
+  size: 1Gi
+```
+
+Then install:
+
+```bash
+helm install beszel-hub ./beszel-hub -f custom-values.yaml
+```
+
+## Advanced Configuration
+
+### Ingress Configuration
+
+Enable and configure Ingress for external access:
+
+```yaml
+ingress:
+  enabled: true
+  className: nginx  # or your ingress class
+  annotations:
+    cert-manager.io/cluster-issuer: "letsencrypt-prod"
+  hosts:
+    - host: beszel.example.com
+      paths:
+        - path: /
+          pathType: Prefix
+  tls:
+    - secretName: beszel-tls
+      hosts:
+        - beszel.example.com
+```
+
+### Persistent Volume Configuration
+
+To use an existing PersistentVolumeClaim:
+
+```yaml
+persistentVolumeClaim:
+  enabled: true
+  existingClaim: "my-existing-pvc"
+```
+
+Or to use a specific storage class:
+
+```yaml
+persistentVolumeClaim:
+  enabled: true
+  storageClass: "fast-ssd"
+  size: 1Gi
+```
+
+### Resource Limits
+
+Set CPU and memory limits:
+
+```yaml
+resources:
+  limits:
+    cpu: 500m
+    memory: 512Mi
+  requests:
+    cpu: 250m
+    memory: 256Mi
+```
+
+### Autoscaling
+
+Enable Horizontal Pod Autoscaler:
+
+```yaml
+autoscaling:
+  enabled: true
+  minReplicas: 2
+  maxReplicas: 10
+  targetCPUUtilizationPercentage: 80
+```
+
+### Node Selection
+
+Schedule pods on specific nodes:
+
+```yaml
+nodeSelector:
+  node-type: monitoring
+
+tolerations:
+  - key: "monitoring"
+    operator: "Equal"
+    value: "true"
+    effect: "NoSchedule"
+```
+
+## Deployment Examples
+
+### Production Setup
+
+```yaml
+replicaCount: 3
+image:
+  tag: "0.17.0"
+service:
+  type: LoadBalancer
+ingress:
+  enabled: true
+  className: nginx
+  hosts:
+    - host: beszel.example.com
+      paths:
+        - path: /
+          pathType: Prefix
+  tls:
+    - secretName: beszel-tls
+      hosts:
+        - beszel.example.com
+persistentVolumeClaim:
+  enabled: true
+  storageClass: "fast-ssd"
+  size: 2Gi
+resources:
+  limits:
+    cpu: 1000m
+    memory: 1Gi
+  requests:
+    cpu: 500m
+    memory: 512Mi
+autoscaling:
+  enabled: true
+  minReplicas: 3
+  maxReplicas: 10
+  targetCPUUtilizationPercentage: 75
+```
+
+### Development/Test Setup
+
+```yaml
+replicaCount: 1
+service:
+  type: ClusterIP
+persistentVolumeClaim:
+  enabled: true
+  size: 500Mi
+resources:
+  limits:
+    cpu: 200m
+    memory: 256Mi
+  requests:
+    cpu: 100m
+    memory: 128Mi
+```
+
+## Managing Beszel Hub
+
+### Upgrade
+
+```bash
+helm upgrade beszel-hub ./beszel-hub
+```
+
+### Check Status
+
+```bash
+# Get deployment status
+kubectl get deployment beszel-hub
+kubectl get pods -l app.kubernetes.io/name=beszel
+
+# Get service info
+kubectl get svc beszel-hub
+```
+
+### View Logs
+
+```bash
+kubectl logs -l app.kubernetes.io/name=beszel -f
+```
+
+### Access Pod Shell
+
+```bash
+kubectl exec -it <pod-name> -- sh
+```
+
+### Uninstall
+
+```bash
+helm uninstall beszel-hub
+```
+
+## Connecting Beszel Agents
+
+After deploying Beszel Hub, you can connect Beszel agents running on:
+- Kubernetes nodes
+- VM instances
+- Bare metal servers
+- Docker containers
+
+Agents communicate with the Hub on port `8090`. Configure the agent with the Hub's address:
+
+```
+HUB_URL=http://beszel-hub.default.svc.cluster.local:8090
+```
+
+Or for external access, use the LoadBalancer IP/DNS or Ingress hostname.
+
+## Troubleshooting
+
+### Pod won't start
+
+```bash
+# Check pod status and events
+kubectl describe pod <pod-name>
+kubectl logs <pod-name>
+```
+
+### Persistent volume issues
+
+```bash
+# Check PVC status
+kubectl get pvc
+kubectl describe pvc beszel-hub
+```
+
+### Connection issues with agents
+
+- Verify the service is accessible: `kubectl get svc beszel-hub`
+- Check network policies aren't blocking traffic
+- Ensure agents can resolve the Hub's DNS name
+- Verify port `8090` is open on the service
+
+### Storage full
+
+Increase PVC size:
+
+```bash
+# Update the PVC size in values
+helm upgrade beszel-hub ./charts/beszel-hub \
+  --set persistentVolumeClaim.size=2Gi
+```
+
+## Security Considerations
+
+- Use network policies to restrict traffic to Beszel Hub
+- Enable RBAC and pod security policies
+- Use TLS/HTTPS via Ingress with cert-manager
+- Regularly update the image to the latest version
+- Consider running with read-only filesystem
+- Use private container registries if applicable
+
+## Persistence
+
+By default, Beszel Hub uses a PersistentVolumeClaim for data storage. Ensure your Kubernetes cluster has enough storage capacity and a default storage class configured.
