# Manage

Manage is a media and server operations tool with Jellyfin integration, SSH file inspection, server monitoring, and safe remote job templates.

See `docs/REQUIREMENTS.md` for the living requirements, decisions, and planning history.
See `docs/MIGRATION_PLAN.md` for the FastAPI + React architecture plan.

- Contributing guide: `CONTRIBUTING.md`

## Architecture

The project consists of two subprojects:

- **`backend/`** — FastAPI Python API (see `backend/README.md`)
- **`frontend/`** — React + TypeScript SPA (see `frontend/README.md`)
- **`archive/`** — Original Streamlit prototype (preserved for reference)

## Features

- Configurable dashboard with persisted widgets (Jellyfin activity, backups summary, Grafana deep-links, Prometheus metrics, Alertmanager alerts, SSH task output, static text) and shortcuts
- Thin-dashboard observability: Alertmanager alerts, Prometheus target health, machine status, and Grafana deep-links (no in-app charting)
- Service registry: configure Jellyfin, Jellyseerr, Alertmanager, Grafana, Prometheus, Nextcloud, and SSH task runner instances in the UI
- Per-machine settings for SSH, monitoring targets, and file browsing
- SQLite-indexed media table with full-library sort/filter
- Read-only Users tab with Jellyfin as the base source and optional Jellyseerr enrichment
- Remote file browser with ffprobe preview and job execution
- Jellyfin API integration for library metadata and user identity data
- SSH-based file inspection and safe remote job templates

## Quick Start

### Docker Compose (recommended)

Production-style deployment with the frontend serving the SPA and proxying `/api` to the backend. The compose files rely on environment-variable interpolation, so export the required values in your shell before running them (no `env_file` is needed):

```bash
docker compose up --build
```

Open the app at <http://localhost:8080>.

The production Compose file requires OIDC and Traefik variables; see [Configuration](#configuration) below. Copy `.env.example` to `.env`, fill in the required values, and export them in your shell before running `docker compose up`.

> **Observability is external.** Manage only ships its **backend** and **frontend**. It does **not** deploy Grafana, Prometheus, Loki, Alertmanager, Alloy, or Node Exporter. The backend exposes a `/metrics` endpoint and optional Alertmanager proxy endpoints so an *existing* observability deployment can scrape and consume them. For a ready-to-run example stack you can deploy alongside Manage, see [`docker-compose.observability.yml`](docker-compose.observability.yml) and [`docs/observability-runbooks.md`](docs/observability-runbooks.md).

Local development with hot reload:

```bash
docker compose -f docker-compose.dev.yml up --build
```

Frontend runs on <http://localhost:5173> and the backend on <http://localhost:8000>. Dev compose disables OIDC by default (`AUTH_ENABLED=false`), so you can open it directly without an identity provider.

The backend media index and settings database (including monitoring machines, SSH keys, saved tasks, and dashboard widgets) are persisted in Docker volumes so rebuilds and container restarts do not reset state.

### Manual backend/frontend development

```bash
cd backend
python -m venv .venv
source .venv/bin/activate
pip install -e '.[dev]'
uvicorn media_library_viewer_api.main:app --reload --port 8000
```

```bash
cd frontend
npm install
npm run dev
```

## Configuration

The Compose files use environment-variable interpolation. Export the required variables in your shell or pass them inline; a `.env` file is optional, not required.

### Compose examples

Production-style example with shell exports:

```bash
export BACKEND_APP_HOST=api.manage.example.com
export FRONTEND_APP_HOST=manage.example.com
export CERT_RESOLVER=letsencrypt
export VITE_OIDC_ISSUER=https://auth.example.com/application/o/manage/
export VITE_OIDC_CLIENT_ID=manage
export VITE_OIDC_REDIRECT_URI=https://manage.example.com/oidc/callback
export VITE_OIDC_POST_LOGOUT_REDIRECT_URI=https://manage.example.com/
export MANAGE_ENCRYPTION_KEY=$(python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())")

docker compose up --build
```

> Observability services (Grafana, Prometheus, Alertmanager) are configured in
> the app on the **Services** page — no env vars for them.

Inline one-liner example:

```bash
BACKEND_APP_HOST=api.manage.example.com FRONTEND_APP_HOST=manage.example.com CERT_RESOLVER=letsencrypt VITE_OIDC_ISSUER=https://auth.example.com/application/o/manage/ VITE_OIDC_CLIENT_ID=manage VITE_OIDC_REDIRECT_URI=https://manage.example.com/oidc/callback VITE_OIDC_POST_LOGOUT_REDIRECT_URI=https://manage.example.com/ docker compose up --build
```

For local development, no SSH key is required unless you want to connect to remote SSH machines later:

```bash
docker compose -f docker-compose.dev.yml up --build
```

Example environment variables:

```bash
# Optional backend logging level
LOG_LEVEL=INFO

# Optional SMTP settings for the Users -> message popup
SMTP_HOST=smtp.example.com
SMTP_PORT=587
SMTP_USERNAME=your-smtp-username
SMTP_PASSWORD=your-smtp-password
SMTP_FROM_ADDRESS=no-reply@example.com
SMTP_FROM_NAME=Manage
SMTP_USE_TLS=true
SMTP_USE_SSL=false
SMTP_TIMEOUT=30

# Jellyfin, Jellyseerr, and SSH targets are now configured per machine in the app's Settings tab.
# The backend seeds a local machine automatically, so no global Jellyfin or SSH env vars are required.
#
# Remote SSH machines can store their private key and optional passphrase directly in Settings,
# so no SSH key mount is required for normal use.

# Authentik / OIDC
AUTH_ENABLED=true
OIDC_ISSUER_URL=https://auth.example.com/application/o/manage/
OIDC_AUDIENCE=manage
OIDC_JWKS_URL=
OIDC_CLOCK_SKEW_SECONDS=30

# Frontend OIDC settings
VITE_OIDC_ENABLED=true
VITE_OIDC_ISSUER=https://auth.example.com/application/o/manage/
VITE_OIDC_CLIENT_ID=manage
VITE_OIDC_SCOPE=openid profile email
VITE_OIDC_REDIRECT_URI=https://manage.example.com/oidc/callback
VITE_OIDC_POST_LOGOUT_REDIRECT_URI=https://manage.example.com/

# Observability services (Grafana, Prometheus, Alertmanager) are configured in
# the app on the Services page. The only observability env var is the optional
# PROMETHEUS_ENABLED toggle (defaults on) for Manage's own /metrics endpoint.

# Required: master key encrypting service secrets (API keys/tokens) at rest.
# Generate one with: python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
MANAGE_ENCRYPTION_KEY=replace-with-a-fernet-key
```

## Remote server requirements

The remote server needs:

- `/bin/sh` (POSIX shell)
- `python3`, `ffprobe`, `find`, `stat`, `df`, `awk` for file inspection and job templates
- SSH access with a key configured in the app's Settings tab

The SSH client rejects unknown host keys. Connect manually once first:

```bash
ssh user@host
```

## Development

```bash
# Backend (lint + tests)
cd backend && .venv/bin/ruff check . && .venv/bin/python -m pytest

# Frontend (lint + typecheck/build + tests)
cd frontend && npm run lint && npm run build && npm run test
```

Focused frontend typecheck: `npx tsc --noEmit`.

## Notes

- Jellyfin server root URL required (not `/web`). The client strips trailing `/web` defensively.
- SSH commands run through `/bin/sh -c` regardless of remote login shell.
- Job templates are shell-quoted. Add new templates in `backend/src/media_library_viewer_api/jobs.py`.
- Root-level Docker Compose files are provided for production (`docker-compose.yml`) and local development (`docker-compose.dev.yml`), and both rely on Compose interpolation rather than `env_file` entries. They deploy **only** the backend and frontend; Manage never deploys its own observability stack (see `docker-compose.observability.yml` for an optional standalone example).
- The configurable dashboard stores widget instances in the backend SQLite settings database. New installs seed default Jellyfin activity and Backups widgets automatically.
- Grafana, Prometheus, and Alertmanager are configured as **service instances** in the app (Services page); their widget adapters resolve URLs from service records, and no observability URLs/credentials live in env vars. No credentials are stored in widget config; service API keys are encrypted at rest with `MANAGE_ENCRYPTION_KEY`. When no alertmanager service is configured, the alert proxy endpoints return graceful "not configured" responses.
