# Deploying raycer to Coolify

raycer runs in production at **https://raycer.altweb.me** as a Docker
Compose application managed by Coolify v4 on the `cool2026` instance.

## Where things live

- **Coolify dashboard:** https://cool2026.altweb.me
- **Server:** `personal` (Linode 91853095, Amsterdam, 2 GB)
  - server UUID: `locg048kwko4sws8wcggc0o4`
  - public IP: `172.235.183.140`
- **Project:** `tools` (UUID `u8wooo0wwk4k8wcw48ww8oo8`)
- **Source:** Forgejo, `https://forgejo-rko8sk40400wscowk4scko0w.altweb.me/spencer/raycer.git`, branch `main` (mirrored to GitLab `spencerflagg/raycer`)
- **Compose file:** `/docker-compose.coolify.yaml` (the local-dev `docker-compose.yml` is for `raycer.test` only and is not used in prod)

## Containers

| Service  | Image source                | Internal port | Public      | Memory limit |
|----------|-----------------------------|---------------|-------------|--------------|
| backend  | built from `./backend`      | 3000          | (internal)  | 256 MiB      |
| frontend | built from `./frontend`     | 80            | raycer.altweb.me | 64 MiB  |

The frontend's nginx reverse-proxies `/api/*` to `http://backend:3000`.

## Required env (set in Coolify dashboard)

| Variable                    | Value                              | Notes |
|-----------------------------|------------------------------------|-------|
| `SERVICE_FQDN_FRONTEND_80`  | `https://raycer.altweb.me`         | Coolify magic var; injects Traefik labels for the frontend service. |

The backend's `NODE_ENV`, `PORT`, and `DB_PATH` are set inside the compose file.

## Persistent storage

A named Docker volume `raycer-data` is mounted into the backend at
`/data` and holds `raycer.sqlite`. Coolify creates and manages this
volume; it survives redeploys.

To inspect or back up:

```bash
ssh root@172.235.183.140
docker volume inspect <coolify-prefixed-name>   # find via: docker volume ls | grep raycer
docker run --rm -v <volume>:/data -v $(pwd):/backup alpine \
  tar czf /backup/raycer-sqlite-$(date +%F).tgz -C /data .
```

## Healthchecks

Both containers have a `HEALTHCHECK` (backend hits `/api/health`,
frontend hits `/`). Coolify's "deployment healthy" gate uses these.

## DNS

A record `raycer.altweb.me -> 172.235.183.140` (Linode domain ID
`1544692`, TTL 300). To recreate:

```bash
linode-cli domains records-create 1544692 \
  --type A --name raycer --target 172.235.183.140 --ttl_sec 300
```

## How the app was created

The Coolify v4 dashboard does not have a great "create from existing
config" path, so the original create call hit the API directly:

```bash
TOKEN=$(jq -r '.instances[] | select(.name=="cool2026") | .token' \
  ~/.config/coolify/config.json)

curl -X POST https://cool2026.altweb.me/api/v1/applications/public \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "project_uuid": "u8wooo0wwk4k8wcw48ww8oo8",
    "server_uuid": "locg048kwko4sws8wcggc0o4",
    "environment_name": "production",
    "git_repository": "https://forgejo-rko8sk40400wscowk4scko0w.altweb.me/spencer/raycer.git",
    "git_branch": "main",
    "build_pack": "dockercompose",
    "docker_compose_location": "/docker-compose.coolify.yaml",
    "name": "raycer",
    "instant_deploy": false
  }'
```

After creation, the FQDN env var was set:

```bash
curl -X POST https://cool2026.altweb.me/api/v1/applications/<APP_UUID>/envs \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"key":"SERVICE_FQDN_FRONTEND_80","value":"https://raycer.altweb.me","is_preview":false}'
```

Then deployed:

```bash
curl -X POST "https://cool2026.altweb.me/api/v1/deploy?uuid=<APP_UUID>&force=false" \
  -H "Authorization: Bearer $TOKEN"
```

## Re-deploy

Pushing to `main` on Forgejo triggers an automatic redeploy via the
Coolify webhook (configured at app create time). To force a manual
redeploy:

```bash
coolify deploy <APP_UUID> --context cool2026
# or
curl -X POST "https://cool2026.altweb.me/api/v1/deploy?uuid=<APP_UUID>" \
  -H "Authorization: Bearer $TOKEN"
```

## Verification

```bash
curl https://raycer.altweb.me/api/health         # {"ok":true,...}
curl https://raycer.altweb.me/api/goals          # both seeded goals
coolify app list --context cool2026 --format json | jq '.[] | select(.name=="raycer")'
```

## Resource notes

The `personal` server is 2 GB and tightly accounted for; `mem_limit`
values in [docker-compose.coolify.yaml](../docker-compose.coolify.yaml)
must be respected. Backend's `better-sqlite3` requires a brief native
compile during the image build (~10 s, ~100 MB peak); first deploy may
take a minute longer than subsequent ones.
