# Coolify deployment — Production ERPNext (+ HRMS, Lending, LMS)

## Prerequisites

- Coolify v4+ with Docker Compose support
- Jenkins green build → image in Forgejo Packages
- **4 GB+ RAM** (8 GB+ recommended)
- Compose file: `docker-compose.yml`

## 1. Create the Coolify service

| Setting | Value |
|---------|--------|
| Type | Docker Compose |
| Repository | `https://git.aexoradao.com/epistemophiliac/erpnext` |
| Branch | `main` |
| Compose file | `docker-compose.yml` |

## 2. Environment variables (Coolify UI)

Copy from [`coolify.env.example`](../coolify.env.example). **Required before first deploy:**

| Variable | Set in Coolify? | Source |
|----------|----------------|--------|
| `CUSTOM_IMAGE` | yes | Jenkins artifact / `dist/coolify-image.env` |
| `CUSTOM_TAG` | yes | e.g. `main-26933f3` (pin) or `main` |
| `PULL_POLICY` | yes | `never` (image-preload loads internally) |
| `REGISTRY_USER` | yes | Forgejo username |
| `REGISTRY_PASSWORD` | yes | Forgejo token (package read) |
| `DB_PASSWORD` | yes | strong secret |
| `ADMIN_PASSWORD` | yes | Frappe `Administrator` password |
| `INSTALL_APPS` | yes | `erpnext,payments,hrms,lending,lms` |
| `SITE_NAME` | **no** (auto) | From Coolify domain via `SERVICE_FQDN_FRONTEND` |
| `FRAPPE_SITE_NAME_HEADER` | **no** (auto) | Same as domain via `SERVICE_FQDN_FRONTEND` |

> **Coolify env cache:** If you previously set `SITE_NAME=erp.example.com` in Coolify, **delete it** so compose defaults use your real domain. Changing `docker-compose.yml` defaults alone does not update stored values.

## 3. Domain (before first deploy)

1. Coolify → your service → **Domains**
2. Add domain, e.g. `erp.aexoradao.com`
3. Attach to service **`frontend`**, port **`8080`**
4. Coolify writes `SERVICE_FQDN_FRONTEND=erp.aexoradao.com` into the stack `.env`
5. Compose sets:
   - `create-site` → `SITE_NAME=erp.aexoradao.com`
   - `frontend` → `FRAPPE_SITE_NAME_HEADER=erp.aexoradao.com`

**Order matters:** assign domain **then** deploy. If `create-site` runs with an empty site name, the stack exits with a clear error.

## 4. Internal image load (automatic)

Compose includes an **`image-preload`** init service (Skopeo → internal Forgejo, same path as Jenkins push). It copies the image into host Docker **before** ERPNext services start — no Cloudflare pull.

Required Coolify env vars (see [`coolify.env.example`](../coolify.env.example)):

```env
REGISTRY_USER=epistemophiliac
REGISTRY_PASSWORD=<forgejo-token>
CUSTOM_IMAGE=git.aexoradao.com/epistemophiliac/erpnext
CUSTOM_TAG=main-26933f3
PULL_POLICY=never
```

Jenkins also preloads the host after each green build, so redeploys are fast.

## 5. First deploy

```text
db → redis → configurator
  → create-site (install apps, ~10–20 min)
  → migrator → backend / workers / frontend
```

Login: `https://your-domain` — user `Administrator`, password = `ADMIN_PASSWORD`.

## 6. Upgrades

1. Jenkins builds new image → update `CUSTOM_TAG` in Coolify
2. Redeploy — `migrator` runs `bench migrate`

## Troubleshooting

| Symptom | Fix |
|---------|-----|
| `SITE_NAME empty` on create-site | Assign domain on `frontend:8080` before deploy |
| Wrong site / 404 nginx | Delete old `SITE_NAME` in Coolify UI; ensure header matches domain |
| Site created with wrong name | Wipe `sites` volume or rename site manually — env change alone won't rename |
| Deploy fails at `Downloading …/487MB` / exit 255 | Image is OK — run `scripts/coolify/preload-image.sh` on host, set `PULL_POLICY=if_not_present`, redeploy |
| Image pull failed | Check `CUSTOM_IMAGE` / `CUSTOM_TAG` in Forgejo Packages; preload on host for private/large registry |
