# StackPilot

A self-hosted Docker Compose manager for power users and homelab enthusiasts —
as intuitive as Dockge, as capable as Portainer for Compose workflows.

> **Status:** Phase 1 (Core) complete. Volume/GPU wizards, image-update checks,
> templates, multi-host agents and backups land in later phases.

## What works today (Phase 1)

- **File-first stacks** — every stack is a plain `compose.yaml` (+ optional `.env`)
  on disk. The DB only stores metadata; nothing is locked in.
- **Auth** — JWT access/refresh tokens, bcrypt hashing, admin/user roles, and a
  first-launch setup wizard that creates the initial admin account.
- **Stack lifecycle** — create, edit, clone, delete, and `up / down / start /
  stop / restart / pull / update` via `docker compose`.
- **Live status** — running / partial / stopped / error / updating, computed from
  Docker container labels.
- **Real-time logs** — streamed over WebSocket, color-coded per service.
- **Monaco editor** — YAML editing with an `.env` tab and a **`docker run` →
  compose** converter.
- **Dashboard** — system resource bar, stack grid with quick actions, and a
  recent-activity audit feed.
- **Auto-discovery** — stacks created outside the UI (any folder under the stacks
  dir containing a compose file) are picked up automatically.
- **Dark / light theme.**

## Architecture

```
frontend (React + Vite + Tailwind, served by nginx)
    │  proxies /api and /ws
    ▼
backend (FastAPI + docker-py + SQLite)
    │  docker-py + `docker compose` CLI
    ▼
Docker Engine (via /var/run/docker.sock — never exposed to the browser)
```

## Quick start

```bash
cd stackpilot
cp .env.example .env
# edit .env and set a strong SECRET_KEY:  openssl rand -base64 48
docker compose up -d --build
```

Open <http://localhost:5009> and complete the first-launch setup wizard to create
your admin account.

### Configuration

All backend settings are environment variables (see `backend/config.py`). The
most important ones:

| Variable        | Default            | Purpose                                   |
|-----------------|--------------------|-------------------------------------------|
| `SECRET_KEY`    | _(auto, dev only)_ | JWT signing key — **set this in prod**    |
| `STACKS_DIR`    | `/opt/stacks`      | Where stack folders live (in-container)   |
| `DATA_DIR`      | `/data`            | SQLite DB + app data                      |
| `CORS_ORIGINS`  | localhost          | Allowed API origins (comma separated)     |

The host path for stacks is set via `STACKS_HOST_DIR` in `.env`.

## Local development

Backend:

```bash
cd backend
python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
SECRET_KEY=dev STACKS_DIR=../data/stacks DATA_DIR=../data uvicorn main:app --reload --port 5008
```

Frontend (proxies to the backend on :5008):

```bash
cd frontend
npm install
npm run dev   # http://localhost:5173
```

## API surface (Phase 1)

```
POST   /api/auth/setup | login | refresh        GET /api/auth/me | needs-setup
GET    /api/stacks                              POST /api/stacks
GET    /api/stacks/{id}                          PUT /api/stacks/{id}   DELETE /api/stacks/{id}
POST   /api/stacks/{id}/{start|stop|restart|pull|update|down|clone}
GET    /api/stacks/{id}/logs                     GET /api/stacks/{id}/export
POST   /api/stacks/convert                       (docker run → compose)
GET    /api/system/info                          GET /api/audit
WS     /ws/logs/{stack_id}[/{service}]           WS  /ws/events
```

## Security notes

- The Docker socket is only ever touched by the backend process; it is never
  proxied to the browser.
- Login is rate-limited (10/min/IP).
- Compose files are backed up to `*.bak` before every overwrite.
- Generated YAML never includes the obsolete `version:` field and uses Compose v2
  (`docker compose`) syntax.
