# Ferrum
Fleet control for Proxmox VE — a single dashboard for every cluster and standalone node you run, with live inventory, dashboards, backups, HA, firewall, alerting, and more.
- **Repository:** https://github.com/anand34577/ferrum
- **Backend:** Go (chi router), SQLite or PostgreSQL
- **Frontend:** React + TypeScript, Vite, Tailwind CSS v4
## Features
- **Fleet-wide overview** — every connection (PVE cluster, standalone node, or PBS remote) rolled up into one dashboard: node/guest counts, CPU/memory/storage, active alerts, and a drag-and-drop customizable dashboard with 20+ widgets.
- **Inventory & operations** — nodes, VMs, and LXCs with live consoles/shells (noVNC + xterm.js), snapshots, guest agent file browser, bulk start/stop/migrate, and cross-cluster guest migration.
- **Storage & backups** — pool usage and Ceph health across every connection, backup job status and replication, and PBS remote integration alongside native PVE storage.
- **High availability, firewall & SDN** — HA groups/resources, cluster and per-node firewall rules, and SDN zones/VNets/subnets, all per connection.
- **Alerting & automation** — threshold-based alerts (CPU/memory/disk/guest), config drift detection, guest lifecycle policies, capacity forecasting, a fleet health score, scheduled health-digest emails, and Terraform/Ansible inventory export.
- **Integrations** — outbound webhooks for real-time events, a REST API and MCP server (scoped API keys, so any MCP-capable agent or script can drive Ferrum), and a built-in AI Assistant that can use any OpenAI-compatible provider — including a zero-config local model (Needle 2) with no API key or network required.
- **Access & auditing** — per-user roles, optional OIDC single sign-on, session/certificate monitoring, and a full audit log of every mutating action across the UI, REST API, and MCP.
- **A dozen look-and-feel presets** — Enterprise, Proxmox-native, Terminal, Glass Flight Deck, Midnight, Paper, Glassmorphism, Neumorphism, Brutalist, Solarized, High Contrast, and Aurora — each with light/dark and a choice of accent colors.

## Getting started
```bash
go build ./cmd/ferrum
./ferrum -config config.example.yaml
```
The web UI is served from the same binary (see `web/embed.go`). For frontend development:
```bash
cd web
npm install
npm run dev
```
On first run, open the UI and create the initial admin account, then add a Proxmox connection (host, port, and either an API token or username/password) from **Connections**.
### Docker
Prebuilt multi-arch (amd64/arm64) images are published to GHCR on every release:
```bash
docker run -p 8080:8080 -v ferrum-data:/app/data ghcr.io/anand34577/ferrum:latest
```
Or build locally from source:
```bash
docker build -t ferrum .
docker run -p 8080:8080 -v ferrum-data:/app/data ferrum
```
## Deploying a release build
Every [GitHub release](https://github.com/anand34577/ferrum/releases) ships prebuilt, statically-linked archives for Linux (amd64/arm64), Windows (amd64/arm64), and macOS (amd64/arm64) — no Go toolchain or CGO dependencies needed on the target machine. Each archive bundles the binary, `config.example.yaml`, and the install script for its OS.
### Linux (systemd)
One-liner, same idea as `get.docker.com` — downloads the latest release for your architecture, verifies its checksum, and installs it as a systemd service:
```bash
curl -fsSL https://raw.githubusercontent.com/anand34577/ferrum/main/scripts/get.sh | sudo sh
```
Pin a specific version with `FERRUM_VERSION`:
```bash
curl -fsSL https://raw.githubusercontent.com/anand34577/ferrum/main/scripts/get.sh | FERRUM_VERSION=v1.2.3 sudo sh
```
Or do it by hand from a downloaded archive — `scripts/get.sh` just automates these same steps:
```bash
tar -xzf ferrum_*_linux_amd64.tar.gz
cd ferrum_*_linux_amd64
sudo ./install.sh
```
Either way, this creates a dedicated `ferrum` system user, installs the binary to `/usr/local/bin/ferrum`, seeds `/etc/ferrum/config.yaml`, and enables + starts the `ferrum.service` systemd unit (`packaging/systemd/ferrum.service`) — data lives in `/var/lib/ferrum`, logs go to `journalctl -u ferrum -f`.
To uninstall, grab [`scripts/linux/uninstall.sh`](scripts/linux/uninstall.sh) and run it as root — add `-- --purge` to also remove config/data:
```bash
curl -fsSL https://raw.githubusercontent.com/anand34577/ferrum/main/scripts/linux/uninstall.sh | sudo bash -s --
```
### Windows (Windows Service)
```powershell
Expand-Archive ferrum_*_windows_amd64.zip
cd ferrum_*_windows_amd64
.\install-service.ps1 # run as Administrator
```
This installs the binary to `%ProgramFiles%\Ferrum`, seeds `%ProgramData%\Ferrum\config.yaml`, and registers a "Ferrum" Windows service — `ferrum.exe` detects it's running under the Service Control Manager and manages its own start/stop lifecycle, no wrapper (NSSM etc.) needed. Since Windows services don't capture stdout/stderr the way systemd does, logs are written to `%ProgramData%\Ferrum\ferrum.log`. Uninstall with `.\uninstall-service.ps1` (add `-Purge` to also remove config/data).
### Building from source
```bash
scripts/build.sh # current platform only, output in dist/
scripts/build.sh linux/amd64 windows/amd64
scripts/build.sh all # every platform the release workflow builds
```
```powershell
.\scripts\build.ps1 # Windows-native equivalent, current platform only
```
Both build the frontend, cross-compile with version info baked in (`ferrum -version`), and package each target as a `.tar.gz`/`.zip` with its install script — the same thing [`.github/workflows/release.yml`](.github/workflows/release.yml) runs when a `vX.Y.Z` tag is pushed, publishing the resulting archives (and a `checksums.txt`) as GitHub Release assets.
## Configuration
Copy `config.example.yaml` to `config.yaml` and adjust as needed, or set the equivalent `FERRUM_*` environment variables (see the comments in that file for the full list, including SQLite/PostgreSQL, TLS cookie behavior, reverse-proxy support, and optional OIDC single sign-on).
Everything else — notifications, SSO details, security policy, system settings, AI providers, and the REST API/MCP enable switches below — is configured from the admin **Settings** UI once Ferrum is running, not from environment variables.
### Built-in LLM (Needle 2)
The AI Assistant and MCP tool-calling loop can use any OpenAI-chat-completions-compatible provider (OpenAI, Ollama, LM Studio, LocalAI, OpenRouter, ...) configured under **Settings > AI Providers**. There's also an optional zero-config, no-API-key, fully local option backed by [Needle 2](https://huggingface.co/Cactus-Compute/needle2) — a small (45M-parameter) tool-calling model that runs as a self-contained CLI binary with no GPU and no network access required at inference time.
Needle 2 is Apache-2.0 licensed, so on **Windows, Linux, and macOS (amd64 or arm64)** Ferrum ships its official CLI binary baked into the `ferrum` binary itself (`internal/needle/bundled_*.go`, one per platform via `go:embed`) — nothing to download, nothing to configure. On a fresh install (no AI provider configured yet), Ferrum extracts it to a cache file and registers it automatically as the default assistant the first time it starts — no manual "Add provider" step needed. If you've already configured a provider, or want to add/re-add it yourself, use **Settings > AI Providers** > "Add provider" > the **Needle 2 (built-in, local)** preset.
On any other platform (32-bit, RISC-V, Windows/ARM64, ...) there's no bundled binary — Ferrum still never fetches executable content from the network on its own. To enable it there:
1. Download the `needle` CLI binary for your platform from the [Needle 2 files](https://huggingface.co/Cactus-Compute/needle2/tree/main).
2. Point Ferrum at it: set `FERRUM_NEEDLE_BIN=/path/to/needle` (or `needleBinPath` in `config.yaml`) before starting Ferrum. This also overrides the bundled binary on a supported platform, if you'd rather run a different build.
Ferrum starts the binary itself (as a local subprocess, `127.0.0.1`-only) the first time it's used, and stops it on shutdown. If no binary is bundled for the platform and `FERRUM_NEEDLE_BIN` isn't set (or doesn't exist), this provider simply isn't usable — every other provider is unaffected.
**Troubleshooting on small ARM boards (Raspberry Pi and similar SBCs):** Needle does a one-time "tool retrieval" pass over Ferrum's full tool catalog (~60 tools) the first time it's used, which briefly uses noticeably more memory and CPU than steady-state chat — Ferrum already waits up to 60s for that first startup. On a board with very little RAM this pass can get the subprocess killed by the kernel's OOM-killer instead; the error will say `needle process exited: signal: killed`. If you hit that, set `FERRUM_NEEDLE_MAX_TOOLS=` to cap how many tools Needle is given (e.g. `10` keeps just the original read-only lookup tools), trading away the newer create/manage tools for a much lighter embedding pass. If it still fails, the board likely doesn't have enough RAM to run even this small a model reliably — use a real OpenAI-compatible provider instead (a cheap/free hosted API, or Ollama on a separate, beefier machine).
## API access, MCP, and audit logging
Any user can generate long-lived API keys under **Profile > API Keys** — scoped to either the general REST API (`Authorization: Bearer ` against `/api/v1/...`, for 3rd-party integrations and scripts) or the MCP endpoint only (`/mcp`, for Claude Code/Desktop or any other MCP-capable agent — see **Profile > MCP integration** for ready-to-paste config). Both surfaces are off by default and must be turned on by an admin under **Settings > API & MCP**, which also caps how many tool calls the AI Assistant's agent loop can make per message. Every mutating action — through the UI, the REST API, or MCP — is recorded with who, what, and when under **Audit Log** (admin-only).
