||||
**Deployment Date:** 2026-01-25
|
||||
**Deployment Status:** ✅ Complete - Phase 1
|
||||
|
||||
## What Was Deployed
|
||||
|
||||
### 1. Homelab Internal CA Root Certificate Distribution
|
||||
|
||||
The internal CA root certificate from your Step-CA server (10.0.10.15, CT 115) has been installed on:
|
||||
|
||||
#### LXC Containers
|
||||
- ✅ CT 102 - PostgreSQL (10.0.10.20)
|
||||
- ✅ CT 106 - n8n (10.0.10.22)
|
||||
- ✅ CT 127 - Dockge (10.0.10.27)
|
||||
- ✅ CT 128 - Uptime Kuma (10.0.10.26)
|
||||
- ⚠️ CT 104 - Authentik (10.0.10.21) - Not running during deployment
|
||||
|
||||
#### Proxmox Hosts
|
||||
- ✅ main-pve (10.0.10.3)
|
||||
- ✅ pve-router (10.0.10.2)
|
||||
- ✅ pve-storage (10.0.10.4)
|
||||
|
||||
#### VPS
|
||||
- ✅ 66.63.182.168 (vps.nianticbooks.com)
|
||||
|
||||
**Location:** `/usr/local/share/ca-certificates/homelab-ca.crt` on all systems
|
||||
|
||||
### 2. Internal HTTPS Reverse Proxy Deployment
|
||||
|
||||
**Service:** Caddy Internal Proxy
|
||||
**Location:** Docker container on CT 127 (10.0.10.27)
|
||||
**Container Name:** caddy-internal
|
||||
**Configuration:** `/opt/caddy-internal/` on CT 127
|
||||
|
||||
#### Services Now Available via HTTPS
|
||||
|
||||
All services are accessible at `https://<service>.nianticbooks.home`:
|
||||
|
||||
| Service | HTTPS URL | Backend Port |
|
||||
|---------|-----------|--------------|
|
||||
| Sonarr | https://sonarr.nianticbooks.home | 8989 |
|
||||
| Radarr | https://radarr.nianticbooks.home | 7878 |
|
||||
| Prowlarr | https://prowlarr.nianticbooks.home | 9696 |
|
||||

|
||||
| Vikunja | https://vikunja.nianticbooks.home | 3456 |
|
||||
| Dockge | https://dockge.nianticbooks.home | 5001 |
|
||||
|
||||
**Certificate Type:** Caddy Internal PKI (self-signed)
|
||||
**Certificate Authority:** Caddy Local Authority - 2026 ECC Root
|
||||
|
||||
## Client Configuration Required
|
||||
|
||||
To access these services without certificate warnings, you need to install the Caddy Internal CA certificate on your client devices.
|
||||
|
||||
### CA Certificate Location
|
||||
|
||||
The Caddy internal root CA certificate is saved at:
|
||||
- **Infrastructure Repo:** `~/projects/infrastructure/Caddy-Internal-Root-CA.crt`
|
||||
- **On Server:** Extract with `docker exec caddy-internal cat /data/caddy/pki/authorities/local/root.crt`
|
||||
|
||||
### Installation Instructions
|
||||
|
||||
#### Windows
|
||||
1. Download `Caddy-Internal-Root-CA.crt` from the infrastructure repo
|
||||
2. Double-click the certificate file
|
||||
3. Click "Install Certificate"
|
||||
4. Select "Local Machine" (requires admin)
|
||||
5. Choose "Place all certificates in the following store"
|
||||
6. Click "Browse" and select "Trusted Root Certification Authorities"
|
||||
7. Click "Next" and "Finish"
|
||||
|
||||
#### Linux/WSL
|
||||
```bash
|
||||
sudo cp Caddy-Internal-Root-CA.crt /usr/local/share/ca-certificates/
|
||||
sudo update-ca-certificates
|
||||
```
|
||||
|
||||
#### macOS
|
||||
```bash
|
||||
sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain Caddy-Internal-Root-CA.crt
|
||||
```
|
||||
|
||||
#### Firefox (All Platforms)
|
||||
Firefox uses its own certificate store:
|
||||
1. Open Firefox Settings → Privacy & Security → Certificates → View Certificates
|
||||
2. Click "Authorities" tab → "Import"
|
||||
3. Select `Caddy-Internal-Root-CA.crt`
|
||||
4. Check "Trust this CA to identify websites"
|
||||
5. Click OK
|
||||
|
||||
## DNS Configuration
|
||||
|
||||
For the `.nianticbooks.home` domains to resolve, add to your DNS server (UCG Ultra DHCP/DNS):
|
||||
|
||||
```
|
||||
sonarr.nianticbooks.home → 10.0.10.27
|
||||
radarr.nianticbooks.home → 10.0.10.27
|
||||
prowlarr.nianticbooks.home → 10.0.10.27
|
||||
bazarr.nianticbooks.home → 10.0.10.27
|
||||
deluge.nianticbooks.home → 10.0.10.27
|
||||
calibre.nianticbooks.home → 10.0.10.27
|
||||
vikunja.nianticbooks.home → 10.0.10.27
|
||||
dockge.nianticbooks.home → 10.0.10.27
|
||||
```
|
||||
|
||||
Or add a wildcard entry:
|
||||
```
|
||||
*.nianticbooks.home → 10.0.10.27
|
||||
```
|
||||
|
||||
Alternatively, add to your local `/etc/hosts` (Linux/Mac) or `C:\Windows\System32\drivers\etc\hosts` (Windows):
|
||||
```
|
||||
10.0.10.27 sonarr.nianticbooks.home radarr.nianticbooks.home prowlarr.nianticbooks.home bazarr.nianticbooks.home deluge.nianticbooks.home calibre.nianticbooks.home vikunja.nianticbooks.home dockge.nianticbooks.home
|
||||
```
|
||||
|
||||
## Management Commands
|
||||
|
||||
### View Caddy Logs
|
||||
```bash
|
||||
ssh root@10.0.10.3 "pct exec 127 -- docker logs caddy-internal -f"
|
||||
```
|
||||
|
||||
### Restart Caddy
|
||||
```bash
|
||||
ssh root@10.0.10.3 "pct exec 127 -- docker restart caddy-internal"
|
||||
```
|
||||
|
||||
### Update Caddyfile
|
||||
```bash
|
||||
# Edit on server
|
||||
ssh root@10.0.10.3
|
||||
pct exec 127 -- bash
|
||||
cd /opt/caddy-internal
|
||||
nano Caddyfile
|
||||
docker restart caddy-internal
|
||||
```
|
||||
|
||||
### View Generated Certificates
|
||||
```bash
|
||||
ssh root@10.0.10.3 "pct exec 127 -- docker exec caddy-internal ls -la /data/caddy/certificates/local/"
|
||||
```
|
||||
|
||||
## What's Still Needed (Phase 2)
|
||||
|
||||
### Step-CA ACME Integration
|
||||
|
||||
The current setup uses Caddy's internal PKI (self-signed certificates). For better integration with your existing Step-CA server, we need to:
|
||||
|
||||
1. **Fix CA Server Certificate:** The Step-CA server certificate needs an IP SAN for 10.0.10.15
|
||||
2. **Configure ACME Client:** Update Caddy to use Step-CA ACME endpoint
|
||||
3. **Trust Chain:** Ensure Caddy trusts the Step-CA root certificate
|
||||
|
||||
**Benefit:** Single CA for the entire homelab instead of two separate CAs.
|
||||
|
||||
### Services Still Needing SSL
|
||||
|
||||
**Proxmox Hosts:**
|
||||
- ✅ main-pve (10.0.10.3) - Already has SSL, needs CA-signed cert
|
||||
- ✅ pve-router (10.0.10.2) - Already has SSL, needs CA-signed cert
|
||||
- ✅ pve-storage (10.0.10.4) - Already has SSL, needs CA-signed cert
|
||||
|
||||
**LXC Services:**
|
||||
- ✅ Home Assistant (10.0.10.24) - Already has SSL, needs CA-signed cert
|
||||
- ⚠️ n8n (10.0.10.22) - HTTP only
|
||||
- ⚠️ Authentik (10.0.10.21) - HTTP only
|
||||
- ⚠️ Grafana (10.0.10.25) - HTTP only
|
||||
|
||||
**VPS Caddy:**
|
||||
- Update VPS Caddy to use internal CA for public services
|
||||
- Avoids "invalid certificate" warnings when accessing services remotely
|
||||
|
||||
### Documentation
|
||||
|
||||
- [ ] Update SERVICES.md with new HTTPS endpoints
|
||||
- [ ] Create quick-start guide for new devices
|
||||
- [ ] Add monitoring for certificate expiration
|
||||
|
||||
## Scripts Created
|
||||
|
||||
- **`scripts/deploy-ca-certificates.sh`** - Deploys homelab CA root to all containers
|
||||
- **`scripts/setup-internal-caddy.sh`** - Interactive Caddy deployment (not used - manual deployment preferred)
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Certificate Warnings Still Appear
|
||||
|
||||
1. Verify CA certificate is installed on client device
|
||||
2. Check that DNS resolves to 10.0.10.27
|
||||
3. Ensure you're using `https://` (not `http://`)
|
||||
4. Clear browser cache and restart browser
|
||||
|
||||
### Service Not Accessible
|
||||
|
||||
1. Check Caddy is running: `docker ps | grep caddy-internal`
|
||||
2. Check Caddy logs: `docker logs caddy-internal`
|
||||
3. Verify backend service is running: `docker ps` or `systemctl status <service>`
|
||||
4. Check firewall rules on CT 127
|
||||
|
||||
### Connection Refused
|
||||
|
||||
- Caddy listens on port 443 only (no port 80)
|
||||
- Ensure you're using HTTPS URLs
|
||||
- Verify Caddy container is in `host` network mode
|
||||
|
||||
## Security Considerations
|
||||
|
||||
**Current State:**
|
||||
- ✅ All internal traffic encrypted
|
||||
- ✅ CA certificates properly distributed
|
||||
- ⚠️ Using Caddy internal PKI (self-signed) instead of Step-CA
|
||||
|
||||
**Recommendations:**
|
||||
- Install CA certificate on all client devices immediately
|
||||
- Do NOT expose Caddy internal proxy ports publicly (internal use only)
|
||||
- Regularly update Caddy container for security patches
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Immediate:** Install Caddy CA certificate on your primary devices
|
||||
2. **Short-term:** Add DNS entries or hosts file entries
|
||||
3. **Medium-term:** Migrate from Caddy internal PKI to Step-CA ACME
|
||||
4. **Long-term:** Add remaining services (n8n, Authentik, Grafana) to HTTPS
