Add metrics monitoring stack with VictoriaMetrics, Grafana, and node_exporter

Implement complete monitoring infrastructure following rick-infra principles:

Components:
- VictoriaMetrics: Prometheus-compatible TSDB (7x less RAM usage)
- Grafana: Visualization dashboard with Authentik OAuth/OIDC integration
- node_exporter: System metrics collection (CPU, memory, disk, network)

Architecture:
- All services run as native systemd binaries (no containers)
- localhost-only binding for security
- Grafana uses native OAuth integration with Authentik (not forward_auth)
- Full systemd security hardening enabled
- Proxied via Caddy at metrics.jnss.me with HTTPS

Role Features:
- Unified metrics role (single role for complete stack)
- Automatic role mapping via Authentik groups:
  - authentik Admins OR grafana-admins -> Admin access
  - grafana-editors -> Editor access
  - All others -> Viewer access
- VictoriaMetrics auto-provisioned as default Grafana datasource
- 12-month metrics retention by default
- Comprehensive documentation included

Security:
- OAuth/OIDC SSO via Authentik
- All metrics services bind to 127.0.0.1 only
- systemd hardening (NoNewPrivileges, ProtectSystem, etc.)
- Grafana accessible only via Caddy HTTPS proxy

Documentation:
- roles/metrics/README.md: Complete role documentation
- docs/metrics-deployment-guide.md: Step-by-step deployment guide

Configuration:
- Updated rick-infra.yml to include metrics deployment
- Grafana port set to 3001 (Gitea uses 3000)
- Ready for multi-host expansion (designed for future node_exporter deployment to production hosts)

+# jnss-web Static Site Deployment Guide
+
+## Overview
+
+This document describes the deployment process for jnss-web, a SvelteKit-based static website serving as the primary entrypoint for jnss.me.
+
+## Architecture
+
+- **Technology**: SvelteKit v2 with static adapter
+- **Build Tool**: Bun
+- **Deployment**: Ansible playbook with git-based artifact deployment
+- **Web Server**: Caddy (direct file serving)
+- **Repository**: git.jnss.me/joakim/jnss-web
+- **Branch Strategy**: 
+  - `main` - Source code
+  - `deploy` - Build artifacts only
+
+## Server Architecture
+
+```
+/opt/jnss-web-repo/          # Git clone of deploy branch
+/var/www/jnss-web/           # Synced build artifacts (served by Caddy)
+/etc/caddy/sites-enabled/
+  └── jnss-web.caddy         # Site config with www redirect
+/var/log/caddy/jnss-web.log  # Access logs
+```
+
+## Development Workflow
+
+### 1. Local Development (main branch)
+
+```bash
+cd ~/dev/jnss-web
+git checkout main
+
+# Make changes to source code
+# ...
+
+# Test locally
+bun run dev
+
+# Build to verify
+bun run build
+```
+
+### 2. Prepare Deploy Branch
+
+```bash
+# Build production version
+bun run build
+
+# Switch to deploy branch
+git checkout deploy
+
+# Merge changes from main
+git merge main --no-commit
+
+# Rebuild to ensure fresh build
+bun run build
+
+# Add only build artifacts
+git add build/
+
+# Commit with descriptive message
+git commit -m "Deploy: Add new feature X"
+
+# Push to Gitea
+git push origin deploy
+```
+
+### 3. Deploy to Server
+
+```bash
+cd ~/rick-infra
+
+# Run deployment playbook
+ansible-playbook -i inventory/hosts.yml playbooks/deploy-jnss-web.yml
+
+# Watch logs (optional)
+ssh root@arch-vps 'tail -f /var/log/caddy/jnss-web.log'
+```
+
+## Playbook Details
+
+### Variables
+
+Located in `playbooks/deploy-jnss-web.yml`:
+
+- `jnss_web_repo_owner`: Your Gitea username (default: "joakim")
+- `jnss_web_branch`: Branch to deploy (default: "deploy")
+- `jnss_web_domain`: Primary domain (default: "jnss.me")
+
+### Tags
+
+- `jnss-web` - All jnss-web tasks
+- `deploy` - Git clone/sync tasks
+- `caddy` - Caddy configuration tasks
+
+### Example Usage
+
+```bash
+# Full deployment
+ansible-playbook -i inventory/hosts.yml playbooks/deploy-jnss-web.yml
+
+# Only update Caddy config (no git pull)
+ansible-playbook -i inventory/hosts.yml playbooks/deploy-jnss-web.yml --tags caddy
+
+# Only sync files (skip Caddy reload)
+ansible-playbook -i inventory/hosts.yml playbooks/deploy-jnss-web.yml --tags deploy
+```
+
+## Initial Setup
+
+### jnss-web Project Configuration
+
+The following changes need to be made in the jnss-web project:
+
+#### 1. Install Static Adapter
+
+```bash
+cd ~/dev/jnss-web
+bun add -D @sveltejs/adapter-static
+```
+
+#### 2. Update svelte.config.js
+
+```javascript
+import adapter from '@sveltejs/adapter-static';
+
+/** @type {import('@sveltejs/kit').Config} */
+const config = {
+    kit: {
+        adapter: adapter({
+            pages: 'build',
+            assets: 'build',
+            fallback: undefined,
+            precompress: false,
+            strict: true
+        })
+    }
+};
+
+export default config;
+```
+
+#### 3. Create src/routes/+layout.js
+
+```javascript
+export const prerender = true;
+```
+
+#### 4. Update .gitignore
+
+Comment out or remove the build directory from .gitignore:
+
+```gitignore
+# build/  <- Comment this out or remove it
+```
+
+#### 5. Create Deploy Branch
+
+```bash
+# Build the site first
+bun run build
+
+# Create and switch to deploy branch
+git checkout -b deploy
+
+# Remove source files (keep only build artifacts)
+git rm -r src static *.config.js package.json bun.lock jsconfig.json .npmrc
+
+# Keep only build/ and documentation
+git add build/ README.md
+
+# Commit
+git commit -m "Initial deploy branch with build artifacts"
+
+# Push to Gitea
+git push -u origin deploy
+
+# Switch back to main
+git checkout main
+```
+
+## Troubleshooting
+
+### Build Directory Not Found
+
+**Error**: "Build directory not found in repository"
+
+**Solution**: Ensure you pushed the build artifacts to the deploy branch:
+```bash
+git checkout deploy
+ls -la build/  # Should exist
+git log --oneline -1  # Verify latest commit
+```
+
+### Caddy Not Serving New Content
+
+**Solution**: 
+```bash
+# SSH to server
+ssh root@arch-vps
+
+# Check Caddy status
+systemctl status caddy
+
+# Reload Caddy manually
+systemctl reload caddy
+
+# Check logs
+journalctl -u caddy -f
+```
+
+### Permission Issues
+
+**Solution**:
+```bash
+# SSH to server
+ssh root@arch-vps
+
+# Fix ownership
+chown -R caddy:caddy /var/www/jnss-web
+
+# Verify
+ls -la /var/www/jnss-web
+```
+
+### Git Clone Fails
+
+**Error**: Unable to clone from git.jnss.me
+
+**Solution**: 
+- Verify repository is public in Gitea
+- Test clone manually: `git clone https://git.jnss.me/joakim/jnss-web.git /tmp/test`
+- Check Gitea service status
+
+## Rollback Procedure
+
+### Option 1: Rollback Deploy Branch
+
+```bash
+# In jnss-web repository
+git checkout deploy
+
+# Find previous commit
+git log --oneline
+
+# Reset to previous commit
+git reset --hard <commit-hash>
+
+# Force push
+git push -f origin deploy
+
+# Re-run deployment
+cd ~/rick-infra
+ansible-playbook -i inventory/hosts.yml playbooks/deploy-jnss-web.yml
+```
+
+### Option 2: Quick Server-Side Rollback
+
+```bash
+# SSH to server
+ssh root@arch-vps
+
+# Go to repo directory
+cd /opt/jnss-web-repo
+
+# Reset to previous commit
+git reset --hard HEAD~1
+
+# Re-sync
+rsync -av --delete build/ /var/www/jnss-web/
+
+# Reload Caddy
+systemctl reload caddy
+```
+
+## Security Considerations
+
+- Repository is public (contains only build artifacts)
+- No secrets in build output
+- Caddy serves only /var/www/jnss-web (no parent directory access)
+- Security headers configured in Caddy
+- HTTPS enforced via Caddy with Let's Encrypt
+
+## Performance Optimizations
+
+- Static assets cached for 1 year (immutable)
+- HTML cached for 1 hour with revalidation
+- Gzip compression enabled
+- No server-side processing required
+
+## Monitoring
+
+### Check Deployment Status
+
+```bash
+# From control machine
+ansible homelab -i inventory/hosts.yml -m shell -a "ls -lh /var/www/jnss-web"
+```
+
+### View Access Logs
+
+```bash
+ssh root@arch-vps 'tail -100 /var/log/caddy/jnss-web.log | jq .'
+```
+
+### Check Site Health
+
+```bash
+curl -I https://jnss.me
+curl -I https://www.jnss.me  # Should redirect to jnss.me
+```
+

+# Metrics Stack Deployment Guide
+
+Complete guide to deploying the monitoring stack (VictoriaMetrics, Grafana, node_exporter) on rick-infra.
+
+## Overview
+
+The metrics stack provides:
+- **System monitoring**: CPU, memory, disk, network via node_exporter
+- **Time-series storage**: VictoriaMetrics (Prometheus-compatible, 7x less RAM)
+- **Visualization**: Grafana with Authentik SSO integration
+- **Access**: `https://metrics.jnss.me` with role-based permissions
+
+## Architecture
+
+```
+User → metrics.jnss.me (HTTPS)
+  ↓
+Caddy (Reverse Proxy)
+  ↓
+Grafana (OAuth → Authentik for SSO)
+  ↓
+VictoriaMetrics (Time-series DB)
+  ↑
+node_exporter (System Metrics)
+```
+
+All services run on localhost only, following rick-infra security principles.
+
+## Prerequisites
+
+### 1. Caddy Deployed
+```bash
+ansible-playbook rick-infra.yml --tags caddy
+```
+
+### 2. Authentik Deployed
+```bash
+ansible-playbook rick-infra.yml --tags authentik
+```
+
+### 3. DNS Configuration
+Ensure `metrics.jnss.me` points to arch-vps IP:
+```bash
+dig metrics.jnss.me  # Should return 69.62.119.31
+```
+
+## Step 1: Configure Authentik OAuth Provider
+
+### Create OAuth2/OIDC Provider
+
+1. Login to Authentik at `https://auth.jnss.me`
+
+2. Navigate to **Applications → Providers** → **Create**
+
+3. Configure provider:
+   - **Name**: `Grafana`
+   - **Type**: `OAuth2/OpenID Provider`
+   - **Authentication flow**: `default-authentication-flow`
+   - **Authorization flow**: `default-provider-authorization-explicit-consent`
+   - **Client type**: `Confidential`
+   - **Client ID**: `grafana`
+   - **Client Secret**: Click **Generate** and **copy the secret**
+   - **Redirect URIs**: `https://metrics.jnss.me/login/generic_oauth`
+   - **Signing Key**: Select auto-generated key
+   - **Scopes**: `openid`, `profile`, `email`, `groups`
+
+4. Click **Finish**
+
+### Create Application
+
+1. Navigate to **Applications** → **Create**
+
+2. Configure application:
+   - **Name**: `Grafana`
+   - **Slug**: `grafana`
+   - **Provider**: Select `Grafana` provider created above
+   - **Launch URL**: `https://metrics.jnss.me`
+
+3. Click **Create**
+
+### Create Groups (Optional)
+
+For role-based access control:
+
+1. Navigate to **Directory → Groups** → **Create**
+
+2. Create groups:
+   - **grafana-admins**: Full admin access to Grafana
+   - **grafana-editors**: Can create/edit dashboards
+   - All other users get Viewer access
+
+3. Add users to groups as needed
+
+## Step 2: Configure Vault Variables
+
+Edit vault file:
+```bash
+ansible-vault edit host_vars/arch-vps/vault.yml
+```
+
+Add these variables:
+```yaml
+# Grafana admin password (for emergency local login)
+vault_grafana_admin_password: "your-secure-admin-password"
+
+# Grafana secret key (generate with: openssl rand -base64 32)
+vault_grafana_secret_key: "your-random-32-char-secret-key"
+
+# OAuth credentials from Authentik
+vault_grafana_oauth_client_id: "grafana"
+vault_grafana_oauth_client_secret: "paste-secret-from-authentik-here"
+```
+
+Save and close (`:wq` in vim).
+
+## Step 3: Deploy Metrics Stack
+
+Deploy all components:
+```bash
+ansible-playbook rick-infra.yml --tags metrics
+```
+
+This will:
+1. Install and configure VictoriaMetrics
+2. Install and configure node_exporter
+3. Install and configure Grafana with OAuth
+4. Deploy Caddy configuration for `metrics.jnss.me`
+
+Expected output:
+```
+PLAY RECAP *******************************************************
+arch-vps : ok=25 changed=15 unreachable=0 failed=0 skipped=0
+```
+
+## Step 4: Verify Deployment
+
+### Check Services
+
+SSH to arch-vps and verify services:
+```bash
+# Check all services are running
+systemctl status victoriametrics grafana node_exporter
+
+# Check service health
+curl http://127.0.0.1:8428/health   # VictoriaMetrics
+curl http://127.0.0.1:9100/metrics  # node_exporter
+curl http://127.0.0.1:3000/api/health  # Grafana
+```
+
+### Check HTTPS Access
+
+```bash
+curl -I https://metrics.jnss.me
+# Should return 200 or 302 (redirect to Authentik)
+```
+
+### Check Metrics Collection
+
+```bash
+# Check VictoriaMetrics scrape targets
+curl http://127.0.0.1:8428/api/v1/targets
+
+# Should show node_exporter as "up"
+```
+
+## Step 5: Access Grafana
+
+1. Navigate to `https://metrics.jnss.me`
+2. Click **"Sign in with Authentik"**
+3. Login with your Authentik credentials
+4. You should be redirected to Grafana dashboard
+
+First login will:
+- Auto-create your Grafana user
+- Assign role based on Authentik group membership
+- Grant access to default organization
+
+## Step 6: Verify Data Source
+
+1. In Grafana, navigate to **Connections → Data sources**
+2. Verify **VictoriaMetrics** is listed and default
+3. Click on VictoriaMetrics → **Save & test**
+4. Should show green "Data source is working" message
+
+## Step 7: Create First Dashboard
+
+### Option 1: Import Community Dashboard (Recommended)
+
+1. Navigate to **Dashboards → Import**
+2. Enter dashboard ID: `1860` (Node Exporter Full)
+3. Click **Load**
+4. Select **VictoriaMetrics** as data source
+5. Click **Import**
+
+You now have a comprehensive system monitoring dashboard!
+
+### Option 2: Create Custom Dashboard
+
+1. Navigate to **Dashboards → New → New Dashboard**
+2. Click **Add visualization**
+3. Select **VictoriaMetrics** data source
+4. Enter PromQL query:
+   ```promql
+   # CPU usage
+   100 - (avg by (instance) (irate(node_cpu_seconds_total{mode="idle"}[5m])) * 100)
+   ```
+5. Click **Apply**
+
+## Step 8: Configure Alerting (Optional)
+
+Grafana supports alerting on metrics. Configure via **Alerting → Alert rules**.
+
+Example alert for high CPU:
+```promql
+avg by (instance) (irate(node_cpu_seconds_total{mode="idle"}[5m])) * 100 < 20
+```
+
+## Troubleshooting
+
+### OAuth Login Fails
+
+**Symptom**: Redirect to Authentik, but returns error after login
+
+**Solution**:
+1. Verify redirect URI in Authentik matches exactly: `https://metrics.jnss.me/login/generic_oauth`
+2. Check Grafana logs: `journalctl -u grafana -f`
+3. Verify OAuth credentials in vault match Authentik
+
+### No Metrics in Grafana
+
+**Symptom**: Data source working, but no data in dashboards
+
+**Solution**:
+1. Check VictoriaMetrics targets: `curl http://127.0.0.1:8428/api/v1/targets`
+2. Verify node_exporter is up: `systemctl status node_exporter`
+3. Check time range in Grafana (top right) - try "Last 5 minutes"
+
+### Can't Access metrics.jnss.me
+
+**Symptom**: Connection timeout or SSL error
+
+**Solution**:
+1. Verify DNS: `dig metrics.jnss.me`
+2. Check Caddy is running: `systemctl status caddy`
+3. Check Caddy logs: `journalctl -u caddy -f`
+4. Verify Caddy config loaded: `ls /etc/caddy/sites/grafana.caddy`
+
+### Wrong Grafana Role
+
+**Symptom**: User has wrong permissions (e.g., Viewer instead of Admin)
+
+**Solution**:
+1. Verify user is in correct Authentik group (`grafana-admins` or `grafana-editors`)
+2. Logout of Grafana and login again
+3. Check role mapping expression in `roles/metrics/defaults/main.yml`:
+   ```yaml
+   grafana_oauth_role_attribute_path: "contains(groups, 'grafana-admins') && 'Admin' || contains(groups, 'grafana-editors') && 'Editor' || 'Viewer'"
+   ```
+
+## Next Steps
+
+### Add More Hosts
+
+To monitor additional hosts (e.g., mini-vps):
+
+1. Deploy node_exporter to target host
+2. Update VictoriaMetrics scrape config to include remote targets
+3. Configure remote_write or federation
+
+### Add Service Metrics
+
+To monitor containerized services:
+
+1. Expose `/metrics` endpoint in application (port 8080)
+2. Add scrape config in `roles/metrics/templates/scrape.yml.j2`:
+   ```yaml
+   - job_name: 'myservice'
+     static_configs:
+       - targets: ['127.0.0.1:8080']
+   ```
+3. Redeploy metrics role
+
+### Set Up Alerting
+
+1. Configure notification channels in Grafana (Email, Slack, etc.)
+2. Create alert rules for critical metrics
+3. Set up on-call rotation if needed
+
+## Security Notes
+
+- All metrics services run on localhost only
+- Grafana is the only internet-facing component (via Caddy HTTPS)
+- OAuth provides SSO with Authentik (no separate Grafana passwords)
+- systemd hardening enabled on all services
+- Default admin account should only be used for emergencies

+# Vaultwarden SSO Feature Status and Configuration
+
+**Document Date:** December 21, 2025  
+**Last Updated:** December 21, 2025  
+**Status:** SSO Configured, Waiting for Stable Release
+
+---
+
+## Executive Summary
+
+Vaultwarden has been successfully deployed with **SSO integration pre-configured** for Authentik. However, SSO functionality is currently **only available in testing images** and not yet in the stable release. This document explains the current state, our decision to wait for stable, and how to activate SSO when it becomes available.
+
+## Current Deployment Status
+
+### What's Working
+- ✅ Vaultwarden deployed successfully at `https://vault.jnss.me`
+- ✅ PostgreSQL backend via Unix socket
+- ✅ Admin panel accessible and working
+- ✅ Email/password authentication working
+- ✅ SMTP notifications configured
+- ✅ All SSO environment variables correctly configured
+- ✅ Authentik OAuth2 provider created and ready
+
+### What's Not Working (By Design)
+- ❌ SSO login option not appearing on login page
+- ❌ "Use single sign-on" button missing
+
+**Reason:** Using stable image (`vaultwarden/server:latest` v1.34.3) which does not include SSO code.
+
+## Investigation Summary (Dec 21, 2025)
+
+### Problem Reported
+User deployed Vaultwarden with `vaultwarden_sso_enabled: true` and configured Authentik integration following official guides, but no SSO option appeared on the login page.
+
+### Root Cause Identified
+After investigation including:
+- Service status check (healthy, running normally)
+- Environment variable verification (all SSO vars present and correct)
+- Configuration review (matches Authentik integration guide perfectly)
+- API endpoint inspection (`/api/config` returns `"sso":""`)
+- Official documentation review
+
+**Finding:** SSO feature is only compiled into `vaultwarden/server:testing` images, not stable releases.
+
+### Evidence
+
+From [Vaultwarden Official Wiki](https://github.com/dani-garcia/vaultwarden/wiki):
+
+> **Testing features**
+> 
+> Features available in the `testing` docker image:
+> - Single Sign-On (SSO), see [Documentation](https://github.com/dani-garcia/vaultwarden/wiki/Enabling-SSO-support-using-OpenId-Connect)
+
+From [SSO Documentation Page](https://github.com/dani-garcia/vaultwarden/wiki/Enabling-SSO-support-using-OpenId-Connect):
+
+> ⚠️ **Important**
+> 
+> ‼️ ‼️ ‼️  
+> SSO is currently only available in the `:testing` tagged images!  
+> The current stable `v1.34.3` **does not** contain the SSO feature.  
+> ‼️ ‼️ ‼️
+
+### API Response Analysis
+
+```bash
+# API config endpoint shows SSO not available
+curl -s http://127.0.0.1:8080/api/config | grep -o '"sso":"[^"]*"'
+# Returns: "sso":""  ← Empty = feature not compiled in
+
+# Environment variables are set correctly
+podman exec vaultwarden env | grep -i sso
+SSO_ENABLED=true
+SSO_ONLY=false
+SSO_CLIENT_ID=DDOQXdwFn6pi4FtSvo7PK5b63pRzyD552xapTZGr
+SSO_CLIENT_SECRET=02D308Sle2w2NPsi7UaXb3bvKKK4punFDT2LiVqKpzvEFqgPpyLysA8Z5yS4g8t4LYmsI9txLE02l5MtWP5R2RBavLhYHjNFHcwEmvYB94bOJw45YmgiGePaW4NHKcfY
+SSO_AUTHORITY=https://auth.jnss.me/application/o/vaultwarden/
+SSO_SCOPES="openid email profile offline_access"
+# ... etc (all correct)
+```
+
+**Conclusion:** Environment configured correctly, feature simply not available in stable release.
+
+## Decision: Wait for Stable Release
+
+### Rationale
+
+**Why NOT switch to testing image:**
+1. **Production stability** - This is a password manager handling sensitive credentials
+2. **Testing images are volatile** - Frequent updates, potential bugs
+3. **No ETA for stable** - SSO marked as "testing feature" indefinitely
+4. **Current auth works fine** - Email/password login is secure and functional
+5. **Configuration is ready** - When SSO reaches stable, it will work immediately
+
+**Why keep SSO configured:**
+1. **Future-ready** - No additional work needed when SSO stabilizes
+2. **No harm** - Environment variables are ignored by stable image
+3. **Documentation** - Clear record of SSO setup for future reference
+4. **Authentik provider ready** - Already created and configured
+
+### Alternatives Considered
+
+| Option | Pros | Cons | Decision |
+|--------|------|------|----------|
+| Use `testing` image | SSO available now | Unstable, potential data loss, frequent breaking changes | ❌ Rejected |
+| Wait for stable | Stable, reliable, secure | No SSO until unknown future date | ✅ **Selected** |
+| Remove SSO config | Cleaner config | Requires reconfiguration later | ❌ Rejected |
+| Dual deployment | Test SSO separately | Resource waste, complexity | ❌ Rejected |

+
+```bash
+# Deployed environment file
+Location: /opt/vaultwarden/.env
+
+# All SSO variables present and correct
+SSO_ENABLED=true
+SSO_AUTHORITY=https://auth.jnss.me/application/o/vaultwarden/
+SSO_SCOPES="openid email profile offline_access"
+# ... etc
+```
+
+## How to Activate SSO (Future)
+
+When Vaultwarden SSO reaches stable release:
+
+### Automatic Activation (Recommended)
+
+1. **Monitor Vaultwarden releases** for SSO in stable:
+   - Watch: https://github.com/dani-garcia/vaultwarden/releases
+   - Look for: SSO feature in stable image changelog
+
+2. **Update container** (standard maintenance):
+   ```bash
+   ansible-playbook rick-infra.yml --tags vaultwarden --ask-vault-pass
+   ```
+
+3. **Verify SSO is available**:
+   ```bash
+   ssh root@69.62.119.31 "curl -s http://127.0.0.1:8080/api/config | grep sso"
+   # Should return: "sso":"https://vault.jnss.me" or similar
+   ```
+
+4. **Test SSO**:
+   - Navigate to: https://vault.jnss.me
+   - Log out if logged in
+   - Enter verified email address
+   - Click "Use single sign-on" button
+   - Should redirect to Authentik login
+
+**No configuration changes needed** - Everything is already set up correctly.
+
+### Manual Testing (Use Testing Image)
+
+If you want to test SSO before stable release:
+
+1. **Backup current deployment**:
+   ```bash
+   ansible-playbook playbooks/backup-vaultwarden.yml  # Create if needed
+   ```
+
+2. **Change to testing image** in `roles/vaultwarden/defaults/main.yml`:
+   ```yaml
+   vaultwarden_version: "testing"
+   ```
+
+3. **Deploy**:
+   ```bash
+   ansible-playbook rick-infra.yml --tags vaultwarden --ask-vault-pass
+   ```
+
+4. **Test SSO** (same as above)
+
+5. **Revert to stable** when testing complete:
+   ```yaml
+   vaultwarden_version: "latest"
+   ```
+
+**Warning:** Testing images may contain bugs, data corruption risks, or breaking changes. Not recommended for production password manager.
+
+## Verification Commands
+
+### Check Current Image Version
+```bash
+ssh root@69.62.119.31 "podman inspect vaultwarden --format '{{.ImageName}}'"
+# Expected: docker.io/vaultwarden/server:latest
+```
+
+### Check SSO API Status
+```bash
+ssh root@69.62.119.31 "curl -s http://127.0.0.1:8080/api/config | grep -o '\"sso\":\"[^\"]*\"'"
+# Current: "sso":""  (empty = not available)
+# Future:  "sso":"https://vault.jnss.me"  (URL = available)
+```
+
+### Check SSO Environment Variables
+```bash
+ssh root@69.62.119.31 "podman exec vaultwarden env | grep -i sso | sort"
+# Should show all SSO_* variables configured correctly
+```
+
+### Check Vaultwarden Version
+```bash
+ssh root@69.62.119.31 "podman exec vaultwarden /vaultwarden --version"
+# Current: Vaultwarden 1.34.3
+```
+

+
+## Deployment
+
+### Prerequisites
+
+1. **Caddy role deployed** - Required for HTTPS proxy
+2. **Authentik deployed** - Required for OAuth/SSO
+3. **Vault variables configured**:
+   ```yaml
+   # In host_vars/arch-vps/vault.yml
+   vault_grafana_admin_password: "secure-admin-password"
+   vault_grafana_secret_key: "random-secret-key-32-chars"
+   vault_grafana_oauth_client_id: "grafana"
+   vault_grafana_oauth_client_secret: "oauth-client-secret-from-authentik"
+   ```
+
+### Authentik Configuration
+
+Before deployment, create OAuth2/OIDC provider in Authentik:
+
+1. **Create Provider**:
+   - Name: `Grafana`
+   - Type: `OAuth2/OpenID Provider`
+   - Client ID: `grafana`
+   - Client Secret: Generate and save to vault
+   - Redirect URIs: `https://metrics.jnss.me/login/generic_oauth`
+   - Signing Key: Auto-generated
+
+2. **Create Application**:
+   - Name: `Grafana`
+   - Slug: `grafana`
+   - Provider: Select Grafana provider created above
+
+3. **Create Groups** (optional, for role mapping):
+   - `grafana-admins` - Full admin access
+   - `grafana-editors` - Can create/edit dashboards
+   - Users without these groups get Viewer access
+
+### Deploy
+
+```bash
+# Deploy complete metrics stack
+ansible-playbook rick-infra.yml --tags metrics
+
+# Deploy individual components
+ansible-playbook rick-infra.yml --tags victoriametrics
+ansible-playbook rick-infra.yml --tags grafana
+ansible-playbook rick-infra.yml --tags node_exporter
+```
+
+### Verify Deployment
+
+```bash
+# Check service status
+ansible homelab -a "systemctl status victoriametrics grafana node_exporter"
+
+# Check metrics collection
+curl http://127.0.0.1:9100/metrics  # node_exporter metrics
+curl http://127.0.0.1:8428/metrics  # VictoriaMetrics metrics
+curl http://127.0.0.1:8428/api/v1/targets  # Scrape targets
+
+# Access Grafana
+curl -I https://metrics.jnss.me/  # Should redirect to Authentik login
+```
+
+## Usage
+
+### Access Dashboard
+
+1. Navigate to `https://metrics.jnss.me`
+2. Click "Sign in with Authentik"
+3. Authenticate via Authentik SSO
+4. Access granted based on Authentik group membership
+
+### Role Mapping
+
+Grafana roles are automatically assigned based on Authentik groups:
+
+- **Admin**: Members of `grafana-admins` group
+  - Full administrative access
+  - Can manage users, data sources, plugins
+  - Can create/edit/delete all dashboards
+
+- **Editor**: Members of `grafana-editors` group
+  - Can create and edit dashboards
+  - Cannot manage users or data sources
+
+- **Viewer**: All other authenticated users
+  - Read-only access to dashboards
+  - Cannot create or edit dashboards
+
+### Creating Dashboards
+
+Grafana comes with VictoriaMetrics pre-configured as the default data source. Use PromQL queries:
+
+```promql
+# CPU usage
+100 - (avg by (instance) (irate(node_cpu_seconds_total{mode="idle"}[5m])) * 100)
+
+# Memory usage
+node_memory_MemTotal_bytes - node_memory_MemAvailable_bytes
+
+# Disk usage
+100 - ((node_filesystem_avail_bytes / node_filesystem_size_bytes) * 100)
+
+# Network traffic
+irate(node_network_receive_bytes_total[5m])
+```
+
+### Import Community Dashboards
+
+1. Browse dashboards at https://grafana.com/grafana/dashboards/
+2. Recommended for node_exporter:
+   - Dashboard ID: 1860 (Node Exporter Full)
+   - Dashboard ID: 11074 (Node Exporter for Prometheus)
+3. Import via Grafana UI: Dashboards → Import → Enter ID
+
+## Configuration
+
+### Customization
+
+Key configuration options in `roles/metrics/defaults/main.yml`:
+
+```yaml
+# Data retention
+victoriametrics_retention_period: "12"  # months
+
+# Scrape interval
+victoriametrics_scrape_interval: "15s"
+
+# OAuth role mapping (JMESPath expression)
+grafana_oauth_role_attribute_path: "contains(groups, 'grafana-admins') && 'Admin' || contains(groups, 'grafana-editors') && 'Editor' || 'Viewer'"
+
+# Memory limits
+victoriametrics_memory_allowed_percent: "60"
+```
+
+### Adding Scrape Targets
+
+Edit `roles/metrics/templates/scrape.yml.j2`:
+
+```yaml
+scrape_configs:
+  # Add custom application metrics
+  - job_name: 'myapp'
+    static_configs:
+      - targets: ['127.0.0.1:8080']
+        labels:
+          service: 'myapp'
+```
+
+## Operations
+
+### Service Management
+
+```bash
+# VictoriaMetrics
+systemctl status victoriametrics
+systemctl restart victoriametrics
+journalctl -u victoriametrics -f
+
+# Grafana
+systemctl status grafana
+systemctl restart grafana
+journalctl -u grafana -f
+
+# node_exporter
+systemctl status node_exporter
+systemctl restart node_exporter
+journalctl -u node_exporter -f
+```
+
+### Data Locations
+
+```
+/var/lib/victoriametrics/  # Time-series data
+/var/lib/grafana/          # Grafana database and dashboards
+/var/log/grafana/          # Grafana logs
+/etc/victoriametrics/      # VictoriaMetrics config
+/etc/grafana/              # Grafana config
+```
+
+### Backup
+
+VictoriaMetrics data is stored in `/var/lib/victoriametrics`:
+
+```bash
+# Stop service
+systemctl stop victoriametrics
+
+# Backup data
+tar -czf victoriametrics-backup-$(date +%Y%m%d).tar.gz /var/lib/victoriametrics
+
+# Start service
+systemctl start victoriametrics
+```
+
+Grafana dashboards are stored in SQLite database at `/var/lib/grafana/grafana.db`:
+
+```bash
+# Backup Grafana
+systemctl stop grafana
+tar -czf grafana-backup-$(date +%Y%m%d).tar.gz /var/lib/grafana /etc/grafana
+systemctl start grafana
+```
+
+## Security
+
+### Authentication
+- Grafana protected by Authentik OAuth/OIDC
+- Local admin account available for emergency access
+- All services bind to localhost only
+
+### Network Security
+- VictoriaMetrics: `127.0.0.1:8428` (no external access)
+- Grafana: `127.0.0.1:3000` (proxied via Caddy with HTTPS)
+- node_exporter: `127.0.0.1:9100` (no external access)
+
+### systemd Hardening
+All services run with security restrictions:
+- `NoNewPrivileges=true`
+- `ProtectSystem=strict`
+- `ProtectHome=true`
+- `PrivateTmp=true`
+- Read-only filesystem (except data directories)
+
+## Troubleshooting
+
+### Grafana OAuth Not Working
+
+1. Check Authentik provider configuration:
+   ```bash
+   # Verify redirect URI matches
+   # https://metrics.jnss.me/login/generic_oauth
+   ```
+
+2. Check Grafana logs:
+   ```bash
+   journalctl -u grafana -f
+   ```
+
+3. Verify OAuth credentials in vault match Authentik
+
+### No Metrics in Grafana
+
+1. Check VictoriaMetrics scrape targets:
+   ```bash
+   curl http://127.0.0.1:8428/api/v1/targets
+   ```
+
+2. Check node_exporter is running:
+   ```bash
+   systemctl status node_exporter
+   curl http://127.0.0.1:9100/metrics
+   ```
+
+3. Check VictoriaMetrics logs:
+   ```bash
+   journalctl -u victoriametrics -f
+   ```
+
+### High Memory Usage
+
+VictoriaMetrics is configured to use max 60% of available memory. Adjust if needed:
+
+```yaml
+# In roles/metrics/defaults/main.yml
+victoriametrics_memory_allowed_percent: "40"  # Reduce to 40%
+```

+The Nextcloud container's entrypoint uses `version.php` as a marker to determine if installation is needed. We must wait for the container's auto-installation to complete before running configuration commands:
 
-- Container copies files including `version.php`
+- Container must complete first-time setup (copy files, run `occ maintenance:install`)
-- Entrypoint sees `version.php` exists → assumes already installed
+- OCC commands require a fully initialized Nextcloud installation
-- Skips running `occ maintenance:install`
+- Running configuration after installation avoids conflicts with the entrypoint script
-- Result: Empty `config.php`, 503 errors
 
-By deploying custom configs **after** installation completes, we:
+**Configuration Method:**
-- ✅ Allow the container's auto-installation to run properly
+
-- ✅ Override specific configs (like Redis) after the fact
+This role uses **OCC commands via a script** rather than config files because:
-- ✅ Maintain idempotency (subsequent runs just update configs)
+- ✅ **Explicit and verifiable** - Run `occ config:list system` to see exact state
+- ✅ **No file conflicts** - Avoids issues with Docker image's built-in config files
+- ✅ **Fully idempotent** - Safe to re-run during updates
+- ✅ **Single source of truth** - All configuration in one script template

+This role automatically installs and enables the following apps:
+
+- **user_oidc** - OpenID Connect authentication backend for SSO integration
+- **calendar** - Calendar and scheduling application (CalDAV)
+- **contacts** - Contact management application (CardDAV)
+
+To customize the app list, override these variables in your `host_vars`:
+
+```yaml
+nextcloud_apps_install:
+  - user_oidc
+  - calendar
+  - contacts
+  - tasks  # Add more apps as needed
+  - deck
+  - mail
+
+```
+
+## OIDC/SSO Integration
+
+### Prerequisites
+
+Before enabling OIDC, you must create an OIDC application/provider in your identity provider (e.g., Authentik):
+
+**For Authentik:**
+
+1. Navigate to **Applications → Providers**
+2. Click **Create** → **OAuth2/OpenID Provider**
+3. Configure:
+   - **Name**: `Nextcloud`
+   - **Authorization flow**: `default-authentication-flow` (or your preferred flow)
+   - **Client type**: `Confidential`
+   - **Client ID**: Generate or specify (save this)
+   - **Client Secret**: Generate or specify (save this)
+   - **Redirect URIs**: `https://cloud.jnss.me/apps/user_oidc/code`
+   - **Signing Key**: Select your signing certificate
+   - **Scopes**: Add `openid`, `profile`, `email`
+
+4. Create **Application**:
+   - Navigate to **Applications → Applications**
+   - Click **Create**
+   - **Name**: `Nextcloud`
+   - **Slug**: `nextcloud`
+   - **Provider**: Select the provider created above
+   - **Launch URL**: `https://cloud.jnss.me`
+
+5. Note the **Discovery URL**: `https://auth.jnss.me/application/o/nextcloud/.well-known/openid-configuration`
+
+### Configuration
+
+Enable OIDC in your `host_vars/arch-vps/main.yml`:
+
+```yaml
+# OIDC Configuration
+nextcloud_oidc_enabled: true
+nextcloud_oidc_provider_id: "authentik"  # Provider identifier (slug)
+nextcloud_oidc_provider_name: "Authentik SSO"  # Display name on login button
+nextcloud_oidc_discovery_url: "https://auth.jnss.me/application/o/nextcloud/.well-known/openid-configuration"
+
+# Security settings (recommended defaults)
+nextcloud_oidc_unique_uid: true  # Prevents account takeover between providers
+nextcloud_oidc_check_bearer: false
+nextcloud_oidc_send_id_token_hint: true
+
+# Attribute mappings (defaults work for most providers)
+nextcloud_oidc_mapping_display_name: "name"
+nextcloud_oidc_mapping_email: "email"
+nextcloud_oidc_mapping_uid: "preferred_username"  # Or "sub" for UUID
+
+# Optional: Enable single login (auto-redirect to SSO)
+nextcloud_oidc_single_login: false  # Set to true to force SSO login
+```
+
+Add credentials to your vault file `host_vars/arch-vps/vault.yml`:
+
+```yaml
+vault_nextcloud_oidc_client_id: "nextcloud-client-id-from-authentik"
+vault_nextcloud_oidc_client_secret: "nextcloud-client-secret-from-authentik"
+```
+
+### OIDC Scopes
+
+The following scopes are requested from your OIDC provider by default:
+
+```yaml
+nextcloud_oidc_scope: "email profile nextcloud openid"
+```
+
+**Standard scopes:**
+- `openid` - Required for OpenID Connect (contains no claims itself)
+- `email` - User's email address (`email` and `email_verified` claims)
+- `profile` - User's profile information (`name`, `given_name`, `preferred_username`, `picture`, etc.)
+
+**Custom scope for Authentik:**
+- `nextcloud` - Custom scope mapping you create in Authentik (contains `groups`, `quota`, `user_id`)
+
+#### Creating the Nextcloud Scope Mapping in Authentik
+
+The `nextcloud` scope must be created as a custom property mapping in Authentik:
+
+1. Log in to Authentik as administrator
+2. Navigate to **Customization** → **Property mappings** → **Create**
+3. Select type: **Scope mapping**
+4. Configure:
+   - **Name**: `Nextcloud Profile`
+   - **Scope name**: `nextcloud`
+   - **Expression**:
+
+```python
+# Extract all groups the user is a member of
+groups = [group.name for group in user.ak_groups.all()]
+
+# In Nextcloud, administrators must be members of a fixed group called "admin"
+# If a user is an admin in authentik, ensure that "admin" is appended to their group list
+if user.is_superuser and "admin" not in groups:
+    groups.append("admin")
+
+return {
+    "name": request.user.name,
+    "groups": groups,
+    # Set a quota by using the "nextcloud_quota" property in the user's attributes
+    "quota": user.group_attributes().get("nextcloud_quota", None),
+    # To connect an existing Nextcloud user, set "nextcloud_user_id" to the Nextcloud username
+    "user_id": user.attributes.get("nextcloud_user_id", str(user.uuid)),
+}
+```
+
+5. Click **Finish**
+6. Navigate to your Nextcloud provider → **Advanced protocol settings**
+7. Add `Nextcloud Profile` to **Scopes** (in addition to the default scopes)
+
+### Group Provisioning and Synchronization
+
+Automatically sync user group membership from Authentik to Nextcloud.
+
+**Default configuration:**
+
+```yaml
+nextcloud_oidc_group_provisioning: true  # Auto-create groups from Authentik
+nextcloud_oidc_mapping_groups: "groups"  # Claim containing group list
+```
+
+**How it works:**
+
+1. User logs in via OIDC
+2. Authentik sends group membership in the `groups` claim (from the custom scope)
+3. Nextcloud automatically:
+   - Creates groups that don't exist in Nextcloud
+   - Adds user to those groups
+   - Removes user from groups they're no longer member of in Authentik
+
+**Example: Making a user an admin**
+
+Nextcloud requires admins to be in a group literally named `admin`. The custom scope mapping (above) automatically adds `"admin"` to the groups list for Authentik superusers.
+
+Alternatively, manually create a group in Authentik called `admin` and add users to it.
+
+**Quota management:**
+
+Set storage quotas by adding the `nextcloud_quota` attribute to Authentik groups or users:
+
+1. In Authentik, navigate to **Directory** → **Groups** → select your group
+2. Under **Attributes**, add:
+   ```json
+   {
+     "nextcloud_quota": "15 GB"
+   }
+   ```
+3. Users in this group will have a 15 GB quota in Nextcloud
+4. If not set, quota is unlimited

+Follow these steps to set up OIDC authentication with Authentik:
+
+**Step 1: Create the Custom Scope Mapping**
+
+See [Creating the Nextcloud Scope Mapping in Authentik](#creating-the-nextcloud-scope-mapping-in-authentik) above.
+
+**Step 2: Create the OAuth2/OpenID Provider**
+
+1. In Authentik, navigate to **Applications** → **Providers**
+2. Click **Create** → **OAuth2/OpenID Provider**
+3. Configure:
+   - **Name**: `Nextcloud`
+   - **Authorization flow**: `default-authentication-flow` (or your preferred flow)
+   - **Client type**: `Confidential`
+   - **Client ID**: Generate or specify (save this for later)
+   - **Client Secret**: Generate or specify (save this for later)
+   - **Redirect URIs**: `https://cloud.jnss.me/apps/user_oidc/code`
+   - **Signing Key**: Select your signing certificate
+   - Under **Advanced protocol settings**:
+     - **Scopes**: Add `openid`, `email`, `profile`, and `Nextcloud Profile` (the custom scope created in Step 1)
+     - **Subject mode**: `Based on the User's UUID` (or `Based on the User's username` if you prefer usernames)
+
+**Step 3: Create the Application**
+
+1. Navigate to **Applications** → **Applications**
+2. Click **Create**
+3. Configure:
+   - **Name**: `Nextcloud`
+   - **Slug**: `nextcloud`
+   - **Provider**: Select the provider created in Step 2
+   - **Launch URL**: `https://cloud.jnss.me` (optional)
+
+**Step 4: Note the Discovery URL**
+
+The discovery URL follows this pattern:
+```
+https://auth.jnss.me/application/o/<slug>/.well-known/openid-configuration
+```
+
+For the application slug `nextcloud`, it will be:
+```
+https://auth.jnss.me/application/o/nextcloud/.well-known/openid-configuration
+```
+
+**Step 5: Configure Nextcloud Role Variables**
+
+In your `host_vars/arch-vps/main.yml`:
+
+```yaml
+nextcloud_oidc_enabled: true
+nextcloud_oidc_provider_id: "authentik"
+nextcloud_oidc_provider_name: "Authentik"
+nextcloud_oidc_discovery_url: "https://auth.jnss.me/application/o/nextcloud/.well-known/openid-configuration"
+nextcloud_oidc_scope: "email profile nextcloud openid"
+nextcloud_oidc_mapping_uid: "preferred_username"  # Or "sub" for UUID-based IDs
+nextcloud_oidc_mapping_display_name: "name"
+nextcloud_oidc_mapping_email: "email"
+nextcloud_oidc_mapping_groups: "groups"
+nextcloud_oidc_mapping_quota: "quota"
+nextcloud_oidc_group_provisioning: true
+```
+
+In your `host_vars/arch-vps/vault.yml`:
+
+```yaml
+vault_nextcloud_oidc_client_id: "nextcloud"  # Client ID from Authentik
+vault_nextcloud_oidc_client_secret: "very-long-secret-from-authentik"  # Client Secret from Authentik
+```
+
+**Step 6: Deploy and Test**
+
+Run the Nextcloud playbook:
+```bash
+ansible-playbook -i inventory/hosts.yml site.yml --tags nextcloud --ask-vault-pass
+```
+
+### Supported OIDC Providers
+
+The `user_oidc` app supports any **OpenID Connect 1.0** compliant provider:
+
+- **Authentik** (recommended for self-hosted)
+- **Keycloak**
+- **Auth0**
+- **Okta**
+- **Azure AD / Microsoft Entra ID**
+- **Google Identity Platform**
+- **GitHub** (via OIDC)
+- **GitLab**
+- **Authelia**
+- **Kanidm**
+- Any other OIDC 1.0 compliant provider
+
+The `nextcloud_oidc_provider_id` is just an identifier slug - you can use any value like `authentik`, `keycloak`, `auth0`, `mycompany-sso`, etc.
+
+### Verification
+
+After deployment:
+
+1. **Check provider configuration:**
+   ```bash
+   podman exec --user www-data nextcloud php occ user_oidc:provider
+   podman exec --user www-data nextcloud php occ user_oidc:provider authentik
+   ```
+
+2. **Test login:**
+   - Visit `https://cloud.jnss.me`
+   - You should see a "Log in with Authentik SSO" button
+   - Click it to test SSO flow
+   - User account should be auto-created on first login
+
+3. **Check user mapping:**
+   ```bash
+   podman exec --user www-data nextcloud php occ user:list
+   ```
+
+### Troubleshooting OIDC
+
+**Login button doesn't appear:**
+```bash
+# Check if user_oidc app is enabled
+podman exec --user www-data nextcloud php occ app:list | grep user_oidc
+
+# Enable if needed
+podman exec --user www-data nextcloud php occ app:enable user_oidc
+```
+
+**Discovery URL errors:**
+```bash
+# Test discovery URL is accessible from container
+podman exec nextcloud curl -k https://auth.jnss.me/application/o/nextcloud/.well-known/openid-configuration
+```
+
+**JWKS cache issues:**
+```bash
+# Clear JWKS cache
+podman exec --user www-data nextcloud php occ user_oidc:provider authentik \
+    --clientid='your-client-id'
+```
+
+## Email Configuration
+
+Configure Nextcloud to send emails for password resets, notifications, and sharing.
+
+### Configuration
+
+Enable email in your `host_vars/arch-vps/main.yml`:
+
+```yaml
+# Email Configuration
+nextcloud_email_enabled: true
+nextcloud_smtp_host: "smtp.fastmail.com"
+nextcloud_smtp_port: 587
+nextcloud_smtp_secure: "tls"  # tls, ssl, or empty
+nextcloud_smtp_username: "nextcloud@jnss.me"
+nextcloud_mail_from_address: "nextcloud"
+nextcloud_mail_domain: "jnss.me"
+
+# Set admin user's email address
+nextcloud_admin_email: "admin@jnss.me"
+```
+
+Add SMTP password to vault `host_vars/arch-vps/vault.yml`:
+
+```yaml
+vault_nextcloud_smtp_password: "your-smtp-app-password"
+```
+
+### Common SMTP Providers
+
+**Fastmail:**
+```yaml
+nextcloud_smtp_host: "smtp.fastmail.com"
+nextcloud_smtp_port: 587
+nextcloud_smtp_secure: "tls"
+```
+
+**Gmail (App Password required):**
+```yaml
+nextcloud_smtp_host: "smtp.gmail.com"
+nextcloud_smtp_port: 587
+nextcloud_smtp_secure: "tls"
+```
+
+**Office 365:**
+```yaml
+nextcloud_smtp_host: "smtp.office365.com"
+nextcloud_smtp_port: 587
+nextcloud_smtp_secure: "tls"
+```
+
+**SMTP2GO:**
+```yaml
+nextcloud_smtp_host: "mail.smtp2go.com"
+nextcloud_smtp_port: 587
+nextcloud_smtp_secure: "tls"
+```
+
+### Verification
+
+After deployment:
+
+1. **Check SMTP configuration:**
+   ```bash
+   podman exec --user www-data nextcloud php occ config:list system | grep mail
+   ```
+
+2. **Check admin email:**
+   ```bash
+   podman exec --user www-data nextcloud php occ user:setting admin settings email
+   ```
+
+3. **Send test email via Web UI:**
+   - Log in as admin
+   - Settings → Administration → Basic settings
+   - Scroll to "Email server"
+   - Click "Send email" button
+   - Check recipient inbox
+
+### Troubleshooting Email
+
+**Test SMTP connection from container:**
+```bash
+# Install swaks if needed (for testing)
+podman exec nextcloud apk add --no-cache swaks
+
+# Test SMTP connection
+podman exec nextcloud swaks \
+  --to recipient@example.com \
+  --from nextcloud@jnss.me \
+  --server smtp.fastmail.com:587 \
+  --auth LOGIN \
+  --auth-user nextcloud@jnss.me \
+  --auth-password 'your-password' \
+  --tls
+```
+
+**Check Nextcloud logs:**
+```bash
+podman exec --user www-data nextcloud php occ log:watch
+```
+

+# Vaultwarden Password Manager Role
+
+Self-contained Vaultwarden (Bitwarden-compatible) password manager deployment using Podman and PostgreSQL.
+
+## Overview
+
+This role deploys Vaultwarden as a Podman Quadlet container with:
+- **PostgreSQL backend** via Unix socket (777 permissions)
+- **Caddy reverse proxy** with HTTPS and WebSocket support
+- **SSO integration** ready (Authentik OpenID Connect)
+- **SMTP support** for email notifications (optional)
+- **Admin panel** for management
+
+## Architecture
+
+```
+Internet → Caddy (HTTPS) → Vaultwarden Container → PostgreSQL (Unix socket)
+                                                  ↓
+                                            /data volume
+```
+
+### Components
+
+- **Container Image**: `vaultwarden/server:latest` (Docker Hub)
+- **User**: System user `vaultwarden` (non-root)
+- **Port**: 8080 (localhost only)
+- **Domain**: `vault.jnss.me`
+- **Database**: PostgreSQL via Unix socket at `/var/run/postgresql`
+- **Data**: `/opt/vaultwarden/data`
+
+## Dependencies
+
+**Managed Hosts:**
+- `postgresql` role (provides database and Unix socket)
+- `caddy` role (provides reverse proxy)
+
+**Control Node:**
+- `argon2` command-line tool (automatically installed if not present)
+  - Used to hash the admin token securely on the control node
+  - Available in most package managers: `pacman -S argon2`, `apt install argon2`, etc.
+
+## Configuration
+
+### Required Variables
+
+Must be defined in vault (e.g., `group_vars/homelab/vault.yml`):
+
+```yaml
+# Database password
+vault_vaultwarden_db_password: "secure-database-password"
+
+# Admin token (plain text - will be hashed automatically during deployment)
+vault_vaultwarden_admin_token: "your-secure-admin-token"
+
+# SMTP password (if using email)
+vault_vaultwarden_smtp_password: "smtp-password"  # optional
+
+# SSO credentials (if using Authentik integration)
+vault_vaultwarden_sso_client_id: "vaultwarden"  # optional
+vault_vaultwarden_sso_client_secret: "sso-secret"  # optional
+```
+
+### Optional Variables
+
+Override in `group_vars` or `host_vars`:
+
+```yaml
+# Domain
+vaultwarden_domain: "vault.jnss.me"
+
+# Container version
+vaultwarden_version: "latest"
+
+# Registration controls
+vaultwarden_signups_allowed: false  # Disable open registration
+vaultwarden_invitations_allowed: true  # Allow existing users to invite
+
+# SMTP Configuration
+vaultwarden_smtp_enabled: true
+vaultwarden_smtp_host: "smtp.example.com"
+vaultwarden_smtp_port: 587
+vaultwarden_smtp_from: "vault@jnss.me"
+vaultwarden_smtp_username: "smtp-user"
+
+# SSO Configuration (Authentik)
+vaultwarden_sso_enabled: true
+vaultwarden_sso_authority: "https://auth.jnss.me"
+```
+
+## Usage
+
+### Deploy Vaultwarden
+
+```bash
+# Full deployment
+ansible-playbook rick-infra.yml --tags vaultwarden
+
+# Or via site.yml
+ansible-playbook site.yml --tags vaultwarden -l homelab
+```
+
+### Access Admin Panel
+
+1. Set admin token in vault file (plain text):
+   ```yaml
+   # Generate a secure token
+   vault_vaultwarden_admin_token: "$(openssl rand -base64 32)"
+   ```
+
+2. The role automatically hashes the token during deployment:
+   - Hashing occurs on the **control node** using `argon2` CLI
+   - Uses OWASP recommended settings (19MiB memory, 2 iterations, 1 thread)
+   - Idempotent: same token always produces the same hash
+   - The `argon2` package is automatically installed if not present
+
+3. Access: `https://vault.jnss.me/admin` (use the plain text token from step 1)
+
+### Configure SSO (Authentik Integration)
+
+> ⚠️ **IMPORTANT: SSO Feature Status (as of December 2025)**
+> 
+> SSO is currently **only available in `vaultwarden/server:testing` images**.
+> The stable release (v1.34.3) does **NOT** include SSO functionality.
+> 
+> **Current Deployment Status:**
+> - This role is configured with SSO settings ready for when SSO reaches stable release
+> - Using `vaultwarden_version: "latest"` (stable) - SSO will not appear
+> - To test SSO now: Set `vaultwarden_version: "testing"` (not recommended for production)
+> - To wait for stable: Keep current configuration, SSO will activate automatically when available
+> 
+> **References:**
+> - [Vaultwarden Wiki - SSO Documentation](https://github.com/dani-garcia/vaultwarden/wiki/Enabling-SSO-support-using-OpenId-Connect)
+> - [Vaultwarden Testing Features](https://github.com/dani-garcia/vaultwarden/wiki#testing-features)
+> 
+> **Decision:** This deployment keeps SSO configured but uses stable image until SSO feature is production-ready.
+
+Following the [Authentik integration guide](https://integrations.goauthentik.io/security/vaultwarden/):
+
+1. **In Authentik**: Create OAuth2/OpenID Provider
+   - **Name**: `Vaultwarden`
+   - **Client Type**: `Confidential`
+   - **Redirect URIs**: `https://vault.jnss.me/identity/connect/oidc-signin` (must be strict/exact match)
+   - **Scopes**: Under "Advanced protocol settings", ensure these scope mappings are selected:
+     - `authentik default OAuth Mapping: OpenID 'openid'`
+     - `authentik default OAuth Mapping: OpenID 'email'`
+     - `authentik default OAuth Mapping: OpenID 'profile'`
+     - `authentik default OAuth Mapping: OpenID 'offline_access'` ⚠️ **Required**
+   - **Access token validity**: Set to more than 5 minutes
+   - **Note the Client ID, Client Secret, and application slug** (from URL or provider settings)
+
+2. **Update Vault Variables**:
+   ```yaml
+   vault_vaultwarden_sso_client_id: "<client-id-from-authentik>"
+   vault_vaultwarden_sso_client_secret: "<client-secret-from-authentik>"
+   ```
+
+3. **Enable SSO and set authority** in `group_vars/homelab/main.yml`:
+   ```yaml
+   vaultwarden_sso_enabled: true
+   # Replace 'vaultwarden' with your actual application slug
+   vaultwarden_sso_authority: "https://auth.jnss.me/application/o/vaultwarden/"
+   ```
+
+4. **Optional: SSO-Only Mode** (disable password login):
+   ```yaml
+   vaultwarden_sso_only: true  # Requires SSO, disables email+password
+   ```
+
+5. **Redeploy**: 
+   ```bash
+   ansible-playbook rick-infra.yml --tags vaultwarden
+   ```
+
+6. **Test**: Log out, enter a verified email on login page, click "Use single sign-on"
+   - **Note**: With `vaultwarden_version: "latest"`, SSO button will not appear (feature not in stable yet)
+
+## Security Considerations
+
+### Database Access
+
+- Uses PostgreSQL Unix socket with **777 permissions**
+- Security maintained via password authentication (scram-sha-256)
+- See: `docs/socket-permissions-architecture.md`
+
+### Admin Token
+
+- **Never commit plain admin token to git**
+- Use Ansible Vault for `vault_vaultwarden_admin_token`
+- Rotate periodically via admin panel
+
+### User Registration
+
+- Default: **Disabled** (`vaultwarden_signups_allowed: false`)
+- Users must be invited by existing users or created via admin panel
+- Prevents unauthorized account creation
+
+## Maintenance
+
+### Backup
+
+Backup the following:
+
+```bash
+# Database backup (via PostgreSQL role)
+sudo -u postgres pg_dump vaultwarden > vaultwarden-backup.sql
+
+# Data directory (attachments, icons, etc.)
+tar -czf vaultwarden-data-backup.tar.gz /opt/vaultwarden/data
+```
+
+### Update Container
+
+```bash
+# Pull new image and restart
+ansible-playbook rick-infra.yml --tags vaultwarden
+```
+
+### View Logs
+
+```bash
+# Service logs
+journalctl -u vaultwarden -f
+
+# Container logs
+podman logs vaultwarden -f
+```
+
+### Restart Service
+
+```bash
+systemctl restart vaultwarden
+```
+
+## Troubleshooting
+
+### Container won't start
+
+```bash
+# Check container status
+systemctl status vaultwarden
+
+# Check container directly
+podman ps -a
+podman logs vaultwarden
+
+# Verify database connectivity
+sudo -u vaultwarden psql -h /var/run/postgresql -U vaultwarden -d vaultwarden -c "SELECT 1;"
+```
+
+### Database connection errors
+
+1. Verify PostgreSQL is running: `systemctl status postgresql`
+2. Check socket exists: `ls -la /var/run/postgresql/.s.PGSQL.5432`
+3. Verify socket permissions: Should be `srwxrwxrwx` (777)
+4. Test connection as vaultwarden user (see above)
+
+### Can't access admin panel
+
+1. Verify admin token is set in vault file (plain text)
+2. Check that the token was hashed successfully during deployment
+3. Ensure you're using the plain text token to log in
+4. Redeploy to regenerate hash if needed
+
+### SSO not appearing / not working
+
+**Most Common Issue: Using Stable Image**
+
+SSO is only available in testing images. Check your deployment:
+
+```bash
+# Check current image version
+podman inspect vaultwarden --format '{{.ImageName}}'
+
+# Check API config for SSO support
+curl -s http://127.0.0.1:8080/api/config | grep -o '"sso":"[^"]*"'
+# Empty string "" = SSO not available in this image
+# URL present = SSO is available
+```
+
+**If using `vaultwarden_version: "latest"`**: SSO will not appear (feature not in stable yet)
+- **To test SSO**: Set `vaultwarden_version: "testing"` in role defaults or group/host vars
+- **For production**: Wait for SSO to reach stable release (recommended)
+
+**If using `vaultwarden_version: "testing"` and SSO still not working**:
+
+1. Verify Authentik provider configuration:
+   - Check that `offline_access` scope mapping is added
+   - Verify redirect URI matches exactly: `https://vault.jnss.me/identity/connect/oidc-signin`
+   - Ensure access token validity is > 5 minutes
+2. Verify SSO authority URL includes full path with slug:
+   - Should be: `https://auth.jnss.me/application/o/<your-slug>/`
+   - Not just: `https://auth.jnss.me`
+3. Check client ID and secret in vault match Authentik
+4. Verify all required scopes: `openid email profile offline_access`
+5. Check Vaultwarden logs for SSO-related errors:
+   ```bash
+   podman logs vaultwarden 2>&1 | grep -i sso
+   ```
+6. Test SSO flow: Log out, enter verified email, click "Use single sign-on"

+# Vaultwarden Role - Required Vault Variables
+
+This document lists all vault-encrypted variables required by the Vaultwarden role.
+
+## Required Variables
+
+These variables **must** be defined in your vault file (e.g., `group_vars/homelab/vault.yml`):
+
+### Database Credentials
+
+```yaml
+# PostgreSQL database password for vaultwarden user
+vault_vaultwarden_db_password: "your-secure-database-password-here"
+```
+
+**Generation**:
+```bash
+openssl rand -base64 32
+```
+
+### Admin Panel Access
+
+```yaml
+# Plain text admin token (will be hashed during deployment)
+vault_vaultwarden_admin_token: "your-secret-admin-token"
+```
+
+**Generation**:
+```bash
+# Generate a secure random token
+openssl rand -base64 32
+```
+
+**Important**: 
+- Store as **plain text** in vault (the role will hash it automatically)
+- Use the same token to access `/admin` panel
+- The token is automatically hashed on the **control node** using argon2id
+- Hashing uses OWASP recommended settings (m=19456, t=2, p=1)
+- Hashing is **idempotent**: same token always produces same hash
+- The `argon2` package is automatically installed if not present on control node
+- Never commit the vault file unencrypted to git
+
+## Optional Variables
+
+These variables are only needed if you enable specific features:
+
+### SMTP Configuration
+
+Required if `vaultwarden_smtp_enabled: true`:
+
+```yaml
+# SMTP password for sending emails
+vault_vaultwarden_smtp_password: "smtp-password-here"
+```
+
+### SSO Integration (Authentik)
+
+> ⚠️ **SSO Feature Status (December 2025)**
+> 
+> SSO is only available in `vaultwarden/server:testing` images (not in stable yet).
+> This role is configured with SSO ready for when it reaches stable release.
+> 
+> Current deployment uses `vaultwarden_version: "latest"` (stable) - SSO credentials 
+> below are configured but SSO will not appear until feature reaches stable.
+
+Required if `vaultwarden_sso_enabled: true`:
+
+```yaml
+# OAuth2 Client ID from Authentik
+vault_vaultwarden_sso_client_id: "your-client-id-here"
+
+# OAuth2 Client Secret from Authentik
+vault_vaultwarden_sso_client_secret: "your-client-secret-here"
+```
+
+**Setup** (following [Authentik integration guide](https://integrations.goauthentik.io/security/vaultwarden/)):
+1. Create OAuth2/OpenID Provider in Authentik:
+   - Redirect URI: `https://vault.jnss.me/identity/connect/oidc-signin` (exact match)
+   - Add scope mappings: `openid`, `email`, `profile`, `offline_access` (required)
+   - Access token validity: > 5 minutes
+   - Note the **application slug** from the provider URL
+2. Copy Client ID and Secret from Authentik
+3. Add credentials to vault file
+4. Set the SSO authority URL in role configuration:
+   ```yaml
+   vaultwarden_sso_enabled: true
+   vaultwarden_sso_authority: "https://auth.jnss.me/application/o/<your-slug>/"
+   ```
+5. Deploy the role
+6. **Wait for SSO to reach stable**, or use `vaultwarden_version: "testing"` to test now
+
+**Important**: 
+- The SSO authority must include the full path with application slug
+- The `offline_access` scope mapping is **required** for Vaultwarden SSO
+- Access token must be valid for more than 5 minutes
+- SSO is configured and ready but will activate when stable release includes it
+
+## Example Vault File
+
+```yaml
+---
+# group_vars/homelab/vault.yml (encrypted with ansible-vault)
+
+# Vaultwarden - Database
+vault_vaultwarden_db_password: "xK9mP2nR5tY8wQ3vZ7cB6sA4dF1gH0jL"
+
+# Vaultwarden - Admin Panel (plain text, will be hashed automatically)
+vault_vaultwarden_admin_token: "MySecureAdminToken123!"
+
+# Vaultwarden - SMTP (optional)
+vault_vaultwarden_smtp_password: "smtp-app-password-here"
+
+# Vaultwarden - SSO (optional)
+vault_vaultwarden_sso_client_id: "vaultwarden"
+vault_vaultwarden_sso_client_secret: "sso-secret-from-authentik"
+```
+
+## Vault File Management
+
+### Encrypt Vault File
+
+```bash
+ansible-vault encrypt group_vars/homelab/vault.yml
+```
+
+### Edit Vault File
+
+```bash
+ansible-vault edit group_vars/homelab/vault.yml
+```
+
+### Decrypt Vault File (temporary)
+
+```bash
+ansible-vault decrypt group_vars/homelab/vault.yml
+# Make changes
+ansible-vault encrypt group_vars/homelab/vault.yml
+```
+
+## Security Best Practices
+
+1. **Never commit unencrypted vault files**
+2. **Use strong passwords** (32+ characters for database, admin token)
+3. **Rotate credentials periodically** (especially admin token)
+4. **Limit vault password access** (use password manager)
+5. **Use separate passwords** for different services
+6. **Back up vault password** (secure location, not in git)
+
+## Verifying Variables
+
+Test if variables are properly loaded:
+
+```bash
+ansible -m debug -a "var=vault_vaultwarden_db_password" homelab --ask-vault-pass
+```
+
+## Troubleshooting
+
+### Variable not found error
+
+- Ensure vault file is in correct location: `group_vars/homelab/vault.yml`
+- Verify file is encrypted: `file group_vars/homelab/vault.yml`
+- Check variable name matches exactly (case-sensitive)
+- Provide vault password with `--ask-vault-pass`
+
+### Admin token not working
+
+- Verify the plain text token in vault matches what you're entering
+- Check for extra whitespace in vault file
+- Ensure the token was hashed successfully during deployment (check ansible output)
+- Try redeploying the role to regenerate the hash
