For a non-loopback bind, configure_nano_firewall opened the nano port in firewalld to every source, while the summary told the operator to restrict it to the proxy. hasJoined takes no token, so on a public host that port is an auth relay anyone can point a proxy at, spending this host's Mojang egress until Mojang rate-limits it and the operator's own players stop getting in. A new FELIS_NANO_PROXY_CIDR names the proxy. With it, firewalld gets one rich rule that admits the port from that source only, ipv4 or ipv6 by the address given. Without it, no port is opened and the summary prints the rule to add. A re-run closes the port an earlier installer opened to every source. A rule for a previous FELIS_NANO_PROXY_CIDR is not tracked and stays until removed by hand. Hosts without firewalld are handled as before. The value goes into the rule text, so it is checked up front for an address with one prefix length and nothing else. firewalld's own parser accepts both rule forms and refuses an ipv6 address under the ipv4 family. The harness covers the rule for each family, the closed-by-default case, the re-run cleanup, the loopback case and the CIDR check.
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.
- Auto Backup & Restore: Scheduled world backups with one-click rollback from any backup point.
- World Reaper: Worlds idle for more than 15 days are automatically backed up and removed to free disk space.
- 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.
