# Homelab Configs

Docker Compose files and configuration for homelab infrastructure.
All stacks are managed via **Portainer** at http://192.168.88.27:9000 (or https://portainer.jgitta.com).

## Portainer Access

| Item | Value |
|---|---|
| URL | http://192.168.88.27:9000 |
| External URL | https://portainer.jgitta.com |
| API Token | `ptr_1cThi+cjOKeICslJbSzCtUhORF06xUOykbAWPUoTyMU=` |

> **Note:** The API token above is for automation/scripting. Keep it private.
> To call the Portainer API: `curl -H "X-API-Key: <token>" http://192.168.88.27:9000/api/stacks`

> **Important — Volume Paths:** All volume mounts in Portainer stacks **must use absolute paths**
> (e.g. `/srv/docker/myapp/data:/app/data`). Relative paths (e.g. `./data`) resolve to
> Portainer's internal `/data/compose/<id>/` directory and will lose data if the stack is
> redeployed with a different ID. This was audited and corrected on 2026-05-07.

## Caddy Reverse Proxy

Caddy runs on a dedicated VM at **192.168.88.110** (alias: `caddy`) as a systemd service.
It handles all HTTPS termination and reverse proxying for `*.jgitta.com` subdomains.
TLS certificates are obtained automatically via **Cloudflare DNS challenge** (Let's Encrypt).

Config location: `/etc/caddy/` on the caddy VM.

### File Structure

| File | Purpose |
|---|---|
| `Caddyfile` | Main file — sets global options, imports snippets and sites |
| `snippets.caddy` | Reusable blocks: `web_secure`, `internal_only`, `proxy_timeouts`, etc. |
| `sites/infrastructure.caddy` | Management/tool services (portainer, kopia, beszel, pihole, etc.) |
| `sites/media.caddy` | Media and automation stack (jellyfin, sonarr, radarr, next, etc.) |
| `sites/homenet.caddy` | Internal `.homenet` HTTP-only domains (no TLS) |
| `sites/goldengamer.caddy` | goldengamer.org external domain |

### Key Snippets

- **`internal_only`** — Blocks requests from outside `192.168.88.0/24` and `192.168.2.0/24` via `abort`. Used on sensitive services (portainer, pihole, proxmox, etc.).
- **`web_secure`** — Standard security headers + gzip compression.
- **`proxy_timeouts`** — 90s read/write timeouts on upstream connections.

### DNS Notes

- Internal services use **MikroTik DNS** (`192.168.88.1`) to resolve `*.jgitta.com` → `192.168.88.110`.
- Browsers with **DNS-over-HTTPS (DoH)** enabled (e.g. Brave) bypass MikroTik DNS and use public resolvers, which have no record of internal-only subdomains. Disable DoH in browser settings or ensure Cloudflare DNS has grey-cloud records pointing to the WAN IP for all subdomains.
- Public-facing services use **Cloudflare DNS** (grey cloud) → WAN IP → MikroTik port-forwards 443 → Caddy VM.
- `internal_only` services should use grey-cloud Cloudflare records (not orange/proxied) — orange cloud sends traffic from Cloudflare's IPs which `internal_only` will abort, causing a 520 error.

## Data Directory Convention

All stack data is stored under `/srv/docker/<stack-name>/` on each host.
**All Portainer volume mounts must use absolute paths** — relative paths break on stack redeploy.

Old compose files were renamed to `.bak` after migration to Portainer.

## Kopia Backup Notes (updated 2026-05-07)

Kopia backs up Nextcloud data (VM 103) and other sources to TrueNAS NFS.
- Cache limit set to 4 GB content + 512 MB metadata (`kopia cache set`)
- `/tmp` and `/app/logs` are bind-mounted out of the container to prevent overlay2 growth
- After-snapshot hook pings Uptime Kuma heartbeat at `status.jgitta.com` after each backup
- If disk fills up again, check `/srv/docker/kopia/tmp/` for leftover verify/restore artifacts
- Ignore policy active for `/data/.claude` in the Nextcloud data source

## Portainer Agent Notes

Portainer agents run on jellyfin and thinkstation, allowing the central Portainer instance on
siklos to manage all three Docker hosts from one UI.

- **jellyfin agent**: Fully managed by Portainer (Stack ID 36)
- **thinkstation agent**: Shows as "limited" in Portainer UI — this is expected and harmless.
  The portainer-agent cannot redeploy itself through its own proxy (catch-22). The agent
  is stable and the endpoint is fully functional. Agent data is persisted in the
  `portainer_agent_data` Docker named volume so TLS certs survive restarts.
