+# Goldilocks
+
+Kubernetes resource recommendation dashboard powered by VPA:
+
+- **Visual dashboard**: User-friendly web interface for VPA recommendations
+- **Automatic VPA management**: Creates and manages VPA resources per namespace
+- **Multi-workload view**: See all workload recommendations in one place
+- **Quality of Service guidance**: Recommendations for Guaranteed, Burstable, and BestEffort QoS classes
+- **OAuth2 authentication**: Keycloak integration for secure access
+- **Namespace-based monitoring**: Explicit opt-in via labels
+
+## Prerequisites
+
+- Kubernetes cluster (k3s)
+- VPA (Vertical Pod Autoscaler) installed
+- Keycloak (for OAuth2 authentication)
+
+Install VPA first:
+
+```bash
+just vpa::install
+```
+
+## Installation
+
+```bash
+just goldilocks::install
+```
+
+You will be prompted for:
+
+1. **Goldilocks host (FQDN)**: e.g., `goldilocks.example.com`
+2. **OAuth2 Proxy setup**: Optional Keycloak authentication
+
+### What Gets Installed
+
+- Goldilocks controller (creates VPA resources)
+- Goldilocks dashboard (web UI)
+- OAuth2 Proxy (for authentication)
+- IngressRoute (Traefik ingress)
+
+## Access
+
+Access the dashboard at `https://your-goldilocks-host/`
+
+Authentication is handled via OAuth2 Proxy with Keycloak.
+
+## Configuration
+
+Environment variables (set in `.env.local` or override):
+
+```bash
+GOLDILOCKS_NAMESPACE=goldilocks        # Goldilocks namespace
+GOLDILOCKS_HOST=goldilocks.example.com # Dashboard FQDN
+VPA_NAMESPACE=vpa                      # VPA namespace
+KEYCLOAK_REALM=buunstack               # Keycloak realm
+```
+
+## Usage
+
+### Enable Monitoring for a Namespace
+
+Goldilocks uses namespace labels to determine which namespaces to monitor:
+
+```bash
+just goldilocks::enable-namespace <namespace>
+```
+
+Or directly with kubectl:
+
+```bash
+kubectl label namespace <namespace> goldilocks.fairwinds.com/enabled=true
+```
+
+### Disable Monitoring for a Namespace
+
+```bash
+just goldilocks::disable-namespace <namespace>
+```
+
+### View Monitored Namespaces
+
+```bash
+kubectl get namespaces -l goldilocks.fairwinds.com/enabled=true
+```
+
+### Check Status
+
+```bash
+just goldilocks::status
+```
+
+### View Logs
+
+```bash
+just goldilocks::logs-controller    # Controller logs
+just goldilocks::logs-dashboard     # Dashboard logs
+```
+
+## Dashboard Features
+
+### Recommendation Views
+
+The dashboard shows recommendations for three Quality of Service (QoS) classes:
+
+1. **Guaranteed QoS**: Requests = Limits (highest priority, no overcommit)
+2. **Burstable QoS**: Requests < Limits (allows bursting, some overcommit)
+3. **BestEffort QoS**: No requests/limits (lowest priority, full overcommit)
+
+### Workload Information
+
+For each workload, the dashboard displays:
+
+- Current resource settings (requests and limits)
+- VPA recommendations (based on actual usage)
+- Quality of Service class
+- Container-level breakdowns
+
+### Applying Recommendations
+
+Goldilocks is read-only and does not modify workloads. To apply recommendations:
+
+1. Review recommendations in the dashboard
+2. Manually update your Deployment/StatefulSet manifests
+3. Apply changes via kubectl or your CI/CD pipeline
+
+## OAuth2 Proxy Management
+
+### Setup OAuth2 Proxy
+
+If not configured during installation:
+
+```bash
+just goldilocks::setup-oauth2-proxy
+```
+
+### Remove OAuth2 Proxy
+
+To disable authentication:
+
+```bash
+just goldilocks::remove-oauth2-proxy
+```
+
+Note: This will make the dashboard publicly accessible. Use port-forward instead:
+
+```bash
+just goldilocks::port-forward
+```
+
+Then access at `http://localhost:8080`
+
+## Examples
+
+### Monitor Application Namespaces
+
+Enable monitoring for common application namespaces:
+
+```bash
+just goldilocks::enable-namespace dagster
+just goldilocks::enable-namespace trino
+just goldilocks::enable-namespace metabase
+just goldilocks::enable-namespace jupyterhub
+```
+
+### Bulk Enable Monitoring
+
+Enable monitoring for multiple namespaces at once:
+
+```bash
+for ns in dagster trino metabase superset querybook; do
+  kubectl label namespace $ns goldilocks.fairwinds.com/enabled=true --overwrite
+done
+```
+
+### Verify VPA Resources Created
+
+After enabling a namespace, Goldilocks automatically creates VPA resources:
+
+```bash
+kubectl get vpa -n <namespace>
+```
+
+Each workload (Deployment, StatefulSet, etc.) should have a corresponding VPA resource.
+
+## Management
+
+### Port Forward to Dashboard
+
+For local access without OAuth2 Proxy:
+
+```bash
+just goldilocks::port-forward
+```
+
+Access at `http://localhost:8080`
+
+### Uninstall
+
+```bash
+just goldilocks::uninstall
+```
+
+This removes:
+
+- OAuth2 Proxy
+- Helm release
+- VPA resources created by Goldilocks
+- Namespace
+
+Note: VPA installation itself is not removed. Uninstall separately if needed:
+
+```bash
+just vpa::uninstall
+```
+
+## Troubleshooting
+
+### Dashboard Shows "No namespaces are labelled"
+
+No namespaces have monitoring enabled. Label at least one namespace:
+
+```bash
+just goldilocks::enable-namespace default
+```
+
+### No Recommendations Displayed
+
+VPA needs time to collect metrics and generate recommendations:
+
+- Wait 5-10 minutes after enabling a namespace
+- Ensure workloads are actively running
+- Verify VPA resources exist: `kubectl get vpa -n <namespace>`
+- Check VPA recommender logs: `just vpa::logs-recommender`
+
+### VPA Resources Not Created
+
+Verify Goldilocks controller is running:
+
+```bash
+kubectl get pods -n goldilocks -l app.kubernetes.io/component=controller
+```
+
+Check controller logs:
+
+```bash
+just goldilocks::logs-controller
+```
+
+Ensure namespace has the correct label:
+
+```bash
+kubectl get namespace <namespace> --show-labels
+```
+
+### OAuth2 Proxy Authentication Issues
+
+Verify Keycloak client exists:
+
+```bash
+just keycloak::list-clients | grep goldilocks
+```
+
+Check OAuth2 Proxy logs:
+
+```bash
+kubectl logs -n goldilocks -l app=goldilocks-oauth2-proxy
+```
+
+### Dashboard Not Accessible
+
+Check IngressRoute:
+
+```bash
+kubectl get ingressroute -n goldilocks
+```
+
+Verify OAuth2 Proxy is running:
+
+```bash
+kubectl get pods -n goldilocks -l app=goldilocks-oauth2-proxy
+```

+# Vertical Pod Autoscaler (VPA)
+
+Kubernetes resource monitoring and recommendation system:
+
+- **Monitoring-only mode**: Observes workloads without automatic scaling
+- **Prometheus integration**: Metrics collection via Prometheus instead of metrics-server
+- **Resource recommendations**: Generates CPU and memory suggestions based on actual usage
+- **Goldilocks integration**: Works with Goldilocks dashboard for visualization
+- **Non-intrusive**: Does not modify running workloads
+
+## Important Note
+
+**This VPA installation is configured for monitoring and recommendation only**:
+
+- ✅ **Recommender**: Enabled - Analyzes workload metrics and generates recommendations
+- ❌ **Updater**: Disabled - Does NOT automatically apply recommendations to pods
+- ❌ **Admission Controller**: Disabled - Does NOT modify pod resources at creation time
+
+This configuration ensures VPA observes your workloads without affecting them. You can review recommendations and manually adjust resource settings.
+
+## Prerequisites
+
+- Kubernetes cluster (k3s)
+- Prometheus (kube-prometheus-stack) installed
+
+VPA requires Prometheus to collect historical metrics data. Install Prometheus first:
+
+```bash
+just prometheus::install
+```
+
+## Installation
+
+```bash
+just vpa::install
+```
+
+The installation will automatically detect Prometheus and configure VPA to use it as the metrics source.
+
+## Configuration
+
+Environment variables (set in `.env.local` or override):
+
+```bash
+VPA_NAMESPACE=vpa                                                   # VPA namespace
+PROMETHEUS_NAMESPACE=monitoring                                     # Prometheus namespace
+PROMETHEUS_ADDRESS=http://kube-prometheus-stack-prometheus.monitoring.svc:9090  # Prometheus URL
+```
+
+## Usage
+
+### View VPA Status
+
+```bash
+just vpa::status
+```
+
+### View Recommender Logs
+
+```bash
+just vpa::logs-recommender
+```
+
+### View VPA Resources
+
+List all VPA resources across namespaces:
+
+```bash
+kubectl get vpa -A
+```
+
+View specific VPA recommendations:
+
+```bash
+kubectl describe vpa <vpa-name> -n <namespace>
+```
+
+Get recommendation in JSON format:
+
+```bash
+kubectl get vpa <vpa-name> -n <namespace> -o jsonpath='{.status.recommendation}' | jq
+```
+
+### Manual VPA Resource Creation
+
+Create a VPA resource for monitoring:
+
+```yaml
+apiVersion: autoscaling.k8s.io/v1
+kind: VerticalPodAutoscaler
+metadata:
+  name: my-app-vpa
+  namespace: default
+spec:
+  targetRef:
+    apiVersion: apps/v1
+    kind: Deployment
+    name: my-app
+  updatePolicy:
+    updateMode: "Off"  # Monitoring only
+```
+
+Apply with:
+
+```bash
+kubectl apply -f vpa-resource.yaml
+```
+
+## Integration with Goldilocks
+
+VPA alone provides raw recommendations through kubectl commands. For a user-friendly dashboard experience, use Goldilocks:
+
+```bash
+# Install Goldilocks
+just goldilocks::install
+
+# Enable monitoring for specific namespaces
+just goldilocks::enable-namespace <namespace>
+```
+
+Goldilocks automatically creates VPA resources for all workloads in labeled namespaces and presents recommendations in a web dashboard.
+
+## Enabling Automatic Scaling
+
+If you want to enable automatic pod resource updates, modify `values.gomplate.yaml`:
+
+```yaml
+updater:
+  enabled: true
+  replicaCount: 1
+  resources:
+    requests:
+      cpu: 50m
+      memory: 500Mi
+    limits:
+      cpu: 200m
+      memory: 1Gi
+  podMonitor:
+    enabled: true
+
+admissionController:
+  enabled: true
+  replicaCount: 1
+  generateCertificate: true
+  mutatingWebhookConfiguration:
+    failurePolicy: Ignore
+  resources:
+    requests:
+      cpu: 50m
+      memory: 200Mi
+    limits:
+      cpu: 200m
+      memory: 500Mi
+```
+
+Then reinstall:
+
+```bash
+just vpa::install
+```
+
+⚠️ **Warning**: Enabling updater and admission controller will cause VPA to automatically modify pod resources. Test thoroughly before enabling in production.
+
+## VPA Update Modes
+
+VPA supports three update modes (configured in VPA resource):
+
+- **Off** (Monitoring only - Current configuration): Generates recommendations but does not apply them
+- **Initial**: Applies recommendations only when pods are created
+- **Auto**: Automatically applies recommendations by evicting and recreating pods
+
+## Management
+
+### Uninstall
+
+```bash
+just vpa::uninstall
+```
+
+This removes:
+
+- Helm release
+- VPA CRDs
+- Namespace
+
+## Troubleshooting
+
+### Recommender Not Starting
+
+Check Prometheus connectivity:
+
+```bash
+just vpa::logs-recommender
+```
+
+Verify Prometheus is running:
+
+```bash
+kubectl get pods -n monitoring -l app.kubernetes.io/name=prometheus
+```
+
+### No Recommendations Generated
+
+VPA requires workload metrics over time:
+
+- Minimum: A few minutes of runtime
+- Recommended: 24+ hours for accurate recommendations
+
+Verify workload is running and generating metrics:
+
+```bash
+kubectl get pods -n <namespace>
+kubectl top pods -n <namespace>
+```
+
+### VPA Resource Not Created
+
+For Goldilocks-managed VPA resources, ensure:
+
+1. Namespace has label: `goldilocks.fairwinds.com/enabled=true`
+2. Workload is managed by a controller (Deployment, StatefulSet, etc.)
+3. Goldilocks controller is running: `kubectl get pods -n goldilocks`
+
+### Check VPA Components
+
+```bash
+kubectl get pods -n vpa
+```
+
+Should show:
+
+- `vpa-recommender-*`: Running
