The design has claimed since migration 0010 that at most one account can hold a PROVEN email address, with ErrEmailTaken as the 409 a second verifier sees. Neither half ever shipped: no migration created users_verified_email_unique, and VerifyEmailOTP had no guard at all — the sentinel was defined but never returned, so two accounts could both verify one address. The damage is not cosmetic: the pre-session login resolves accounts BY verified email, so the duplicate decided which identity a mailed sign-in code belonged to. - Migration 0020 creates the partial unique index (lower(email) WHERE email_verified) the comments have been citing — the database-level backstop. - VerifyEmailOTP now refuses the take-over with ErrEmailTaken BEFORE consuming the code (the address, not the code, is the problem), charges no attempt, and maps a lost cross-user race (unique violation) to the same answer. - The verify handler answers 409 email_taken instead of a generic 500. Covered by the pgint suite (sequential double-verify refused with the code still live, a direct duplicate write still loses to the index, the refused account can still prove its own address) and a hermetic 409 case.
Felis
A Kubernetes-driven Minecraft server hosting platform — one command to deploy, automatic lifecycle, backup, and security.
一款 Kubernetes 驱动的 Minecraft 服务器托管平台，一行命令部署，自动管理生命周期与安全。
Table of Contents
Features
- Wake on Join: Servers start automatically when a player connects, and stop when idle — like hibernate for your server.
- Web Dashboard: Monitor server status, online players, and resource usage from your browser, with backup and restore management.
- Backup & Restore: One-click snapshots of a server's whole data volume (worlds, config, plugins/mods — the entire /data volume) into the cluster's archive store, with rollback from any backup point — enabled by default (the installer renders the archive PVC and its path).
- World Reaper (opt in): Worlds idle for more than 15 days are automatically backed up and removed to free disk space. Enable it by setting
FELIS_WORLDS_HOST_PATHat install time (on k3s:/var/lib/rancher/k3s/storage); without it, no world is ever deleted. - Multi-core Support: Compatible with Paper, Fabric, Forge, and NeoForge, federated behind a Velocity proxy.
- Modpack Submission: Players submit custom modpacks; admin approval triggers automatic build and deployment.
- Passkey Login: Passwordless authentication via fingerprint, face recognition, or hardware security keys.
- Zero Trust Security: Panel traffic protected by Cloudflare Access; the internal API is never exposed to the internet.
Getting Started
On a prepared Linux host, run:
curl -fsSL https://raw.githubusercontent.com/MliroLirrorsIngenuity/Felis/main/deploy/bootstrap.sh | sudo bash
The script installs K3s, deploys the control plane, and launches a setup wizard. Once done, open your browser at the configured domain.
Build from Source
Felis is built with Go and Node.js:
# Backend (Go 1.26+)
go build -o felis ./cmd/felis
# Frontend (Node.js 22+)
cd panel
npm ci
npm run build
# Docker image
docker build -t felis:custom .

License Notes
- Derivative works are AGPL too: Any distribution of this project or of software derived from it must be released under AGPL-3.0 and must include the original copyright notice and license statement.
- Running it as a network service also triggers the source obligation (AGPL section 13): if you host a modified Felis for other people to use, you must offer those users the complete source of your modified version — even if you never distribute a binary. This is the one substantive difference between AGPL and GPL, and since Felis is a hosting platform reached over a network, it will essentially always apply.
