Initial homelab GitOps repository setup

This commit establishes the foundation for the homelab GitOps repository: - Created layered architecture (infrastructure/platform/apps) - Added MCP servers umbrella chart with SOPS-encrypted secrets - Configured Flux Kustomizations for infrastructure and platform layers - Set up SOPS + Age for secrets management - Added .gitignore and documentation MCP servers include: - Gateway with auth (API keys in encrypted secrets) - n8n MCP (workflow automation) - Playwright MCP (browser automation) - Kubernetes MCP (kubectl operations) - GitHub MCP (repository management) - Gitea MCP (self-hosted git) - SQLite MCP (database operations) - Filesystem MCP (file operations) - Fetch MCP (HTTP requests) - Memory MCP (shared memory/state) All secrets are encrypted with SOPS using Age encryption.

+# Homelab GitOps Repository
+
+This repository contains the declarative configuration for my Kubernetes homelab, managed using FluxCD v2 and SOPS-encrypted secrets.
+
+## Architecture
+
+The repository is organized into three layers:
+
+### Layer 0 - Infrastructure
+Core cluster infrastructure that other applications depend on:
+- **cert-manager**: TLS certificate management
+- **ingress-nginx**: Ingress controller for HTTP/HTTPS routing
+- **storage**: Persistent volume provisioning
+
+### Layer 1 - Platform
+Platform services that support applications:
+- **gitea**: Self-hosted Git server
+- **harbor**: Container registry
+- **n8n**: Workflow automation
+- **mcp-servers**: Model Context Protocol servers with gateway
+- **gotify**: Push notifications
+- **prometheus**: Monitoring and alerting
+
+### Layer 2 - Apps
+User-facing applications:
+- **media**: Audiobookshelf, Media-Servarr stack, MPD
+- **ai**: Ollama, Open WebUI
+- **file-sharing**: Firefox Send, Pairdrop, Pingvin Share, PsiTransfer
+- **utilities**: BentoPDF, Stirling PDF, Minecraft
+
+## Secrets Management
+
+All secrets are encrypted using [SOPS](https://github.com/getsops/sops) with [age](https://github.com/FiloSottile/age) encryption.
+
+### Decrypting Secrets
+
+```bash
+# Decrypt a single file
+sops -d infrastructure/cert-manager/secrets.enc.yaml > secrets.yaml
+
+# Edit encrypted file in-place
+sops infrastructure/cert-manager/secrets.enc.yaml
+```
+
+### Encrypting New Secrets
+
+```bash
+# Encrypt a new secret file
+sops -e secrets.yaml > secrets.enc.yaml
+```
+
+## Deployment
+
+This repository is deployed using FluxCD v2:
+
+```bash
+# Bootstrap Flux (already done)
+flux bootstrap git \
+  --url=http://192.168.1.49:13001/admin/homelab.git \
+  --branch=main \
+  --path=clusters/production
+
+# Check Flux status
+flux get all
+```
+
+## Environment
+
+- **Platform**: K3s on ARM (Raspberry Pi)
+- **OS**: Termux on Android
+- **GitOps**: FluxCD v2
+- **Secrets**: SOPS + Age encryption
+- **Registry**: Harbor (self-hosted)
+

+## Maintenance
+
+### Updating Applications
+
+1. Edit the HelmRelease or Kustomization in the appropriate directory
+2. Commit and push changes to Gitea
+3. Flux will automatically reconcile within 1 minute (or force with `flux reconcile`)
+
+### Adding New Applications
+
+1. Create directory in appropriate layer (infrastructure/platform/apps)
+2. Add namespace.yaml, helmrelease.yaml, and kustomization.yaml
+3. If secrets needed, create secrets.enc.yaml using SOPS
+4. Add reference to layer's kustomization.yaml
+5. Commit and push

+
+## Quick Start
+
+### 1. Prerequisites
+
+```bash
+# Ensure you're in the right directory
+cd /data/data/com.termux/files/home/git/mcp-servers/mcp-umbrella
+
+# Build chart dependencies
+helm dependency build
+```
+
+### 2. Generate API Keys
+
+```bash
+# Generate secure API keys for the gateway
+echo "n8n API key: $(openssl rand -hex 32)"
+echo "admin API key: $(openssl rand -hex 32)"
+```
+
+### 3. Configure Required Secrets
+
+Create a `custom-values.yaml` file:
+
+```yaml
+mcp-gateway:
+  gateway:
+    auth:
+      apiKeys:
+        - name: "n8n"
+          key: "YOUR_N8N_API_KEY_HERE"
+        - name: "admin"
+          key: "YOUR_ADMIN_API_KEY_HERE"
+
+n8n-mcp:
+  n8nMCP:
+    n8n:
+      apiKey: "YOUR_N8N_INSTANCE_API_KEY"
+
+github-mcp:
+  github:
+    token: "YOUR_GITHUB_TOKEN"
+    owner: "your-github-username"
+```
+
+### 4. Deploy

+```bash
+# Create the mcp namespace
+kubectl create namespace mcp
+
+# Install the umbrella chart
+helm install mcp-ecosystem . \
+  --namespace mcp \
+  -f custom-values.yaml
+```
+
+### 5. Verify Deployment
+
+```bash
+# Check all pods
+kubectl get pods -n mcp
+
+# Get gateway LoadBalancer IP
+kubectl get svc -n mcp mcp-ecosystem-mcp-gateway
+
+# Test health endpoint
+GATEWAY_IP=$(kubectl get svc -n mcp mcp-ecosystem-mcp-gateway -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
+curl http://$GATEWAY_IP:3000/health

+## Configuration
+
+### Enabling/Disabling Servers
+
+In your `custom-values.yaml`:
+
+```yaml
+# Enable a disabled server
+prometheus-mcp:
+  enabled: true
+  prometheus:
+    url: "http://your-prometheus-server"
+
+# Disable an enabled server
+playwright-mcp:
+  enabled: false
+```
+
+### Configuring the Gateway
+
+```yaml
+mcp-gateway:
+  service:
+    type: LoadBalancer
+    loadBalancerIP: "192.168.1.100"  # Optional static IP
+
+  ingress:
+    enabled: true  # Enable Ingress (currently disabled)
+    hosts:
+      - host: mcp.caffeinetux.com
+        paths:
+          - path: /
+            pathType: Prefix
+
+  autoscaling:
+    enabled: true
+    minReplicas: 1
+    maxReplicas: 5
+```
+
+### Configuring Memory-MCP Backend
+
+Choose Redis or PostgreSQL:
+
+```yaml
+memory-mcp:
+  storage:
+    backend: "redis"  # or "postgres"
+
+  redis:
+    host: "redis.default.svc.cluster.local"
+    port: 6379
+    password: "your-redis-password"
+```
+
+## Usage Examples
+
+### From n8n Workflow
+
+Use the HTTP Request node:
+
+```javascript
+// n8n HTTP Request Node
+Method: POST
+URL: http://mcp-ecosystem-mcp-gateway.mcp.svc.cluster.local:3000/mcp/playwright-mcp
+Authentication: Header Auth
+Header Name: Authorization
+Header Value: Bearer YOUR_N8N_API_KEY

+```
+
+## Upgrading
+
+```bash
+# Update dependencies
+helm dependency update
+
+# Upgrade the deployment
+helm upgrade mcp-ecosystem . \
+  --namespace mcp \
+  -f custom-values.yaml
+```
+
+## Uninstalling
+
+```bash
+# Remove the deployment
+helm uninstall mcp-ecosystem --namespace mcp
+
+# Optionally delete the namespace
+kubectl delete namespace mcp
+```
+
+## Troubleshooting
+
+### Gateway not accessible
+
+```bash
+# Check gateway pod logs
+kubectl logs -n mcp -l app.kubernetes.io/name=mcp-gateway
+
+# Check service
+kubectl describe svc -n mcp mcp-ecosystem-mcp-gateway
+```
+
+### MCP server not responding
+
+```bash
+# Check specific server logs
+kubectl logs -n mcp -l app.kubernetes.io/name=playwright-mcp
+
+# Check if server is registered in gateway
+curl -H "Authorization: Bearer YOUR_ADMIN_API_KEY" \
+  http://<LoadBalancer-IP>:3000/servers
+```
+
+### Authentication errors
+
+```bash
+# Verify API keys are set
+kubectl get secret -n mcp mcp-ecosystem-mcp-gateway-auth -o yaml
+
+# Test without auth (should fail with 401)
+curl http://<LoadBalancer-IP>:3000/servers
+```
+
+## Resource Requirements
+
+### Minimal Setup (5 servers)
+- **CPU**: ~2 cores total
+- **Memory**: ~3Gi total
+- **Storage**: ~15Gi (PVCs for SQLite, Filesystem, Playwright)
+
+### Full Setup (all 13 servers)
+- **CPU**: ~6 cores total
+- **Memory**: ~10Gi total
+- **Storage**: ~50Gi (with all persistence enabled)
+
+### Per-Server Resources
+
+| Server | CPU Request | CPU Limit | RAM Request | RAM Limit |
+|--------|-------------|-----------|-------------|-----------|
+| Gateway | 100m | 500m | 128Mi | 512Mi |
+| n8n-MCP | 50m | 200m | 128Mi | 256Mi |
+| Playwright | 200m | 1000m | 512Mi | 2Gi |
+| Kubernetes | 100m | 100m | 128Mi | 128Mi |
+| Memory-MCP | 100m | 200m | 256Mi | 512Mi |
+| Others | 50-100m | 100-200m | 64-128Mi | 128-256Mi |
+
+## Security
+
+- **API Key Authentication** on gateway
+- **RBAC** for Kubernetes-MCP cluster access
+- **Secrets** for all credentials (GitHub tokens, database passwords, etc.)
+- **Non-root users** in all containers
+- **Read-only root filesystem** where possible

+# Enable Prometheus monitoring
+prometheus-mcp:
+  enabled: true
+  prometheus:
+    url: "http://prometheus-server.prometheus.svc.cluster.local"
+```
+
+### High Availability
+
+```yaml
+mcp-gateway:
+  replicaCount: 3
+  autoscaling:
+    enabled: true
+    minReplicas: 3
+    maxReplicas: 10
+```
