INTEGRATION-ONLY and KNOWN-LIMITATION are grep-able, but the grep answers the wrong question. Thirty-four Go sites share the two markers and they carry four different meanings: "declared, nothing implements it" reads exactly like "implemented, only its I/O is unreachable from here", and neither reads differently from a limitation that was accepted on purpose and is not coming back. docs/deferred-seams.md sorts them, following the bucketed shape internal/updater/doc.go already uses for its own package rather than starting a second convention. Sorting them turned up two markers that had outlived the condition they describe. config.go called the modpack upload transport a deferred integration after both backends had shipped -- LocalContextStore and S3ContextStore, selected in cmd/felis by the shape of user_uploads_context, with the uploads PVC mounted and the felis-uploads-s3 Secret rendered. What is still deferred is the far end: Kaniko reading that context from inside the build Pod. updater/doc.go listed the `felis update` CLI and the off-cluster Velocity jar read under REMAINING INTEGRATION. Both exist -- cmd/felis/update.go, and gatherer_host.go, which answers Velocity from the installed jar's manifest and felis-api from the running binary's build stamp. The two nil seams that bullet also names are real, but they belong to the in-cluster gatherer only, so the bullet now says which caller has what and which is still empty. The index also records the collision that makes a naive grep misleading: docs/troubleshooting.md uses [INTEGRATION-ONLY] for something else, defined in its own opening at :19 -- the symptom is produced by the kubelet, kaniko or a live handshake, so it cannot be reproduced from the repository. Those twelve marks say where a failure comes from, not that something is unbuilt, and are excluded. Both code changes are comments. Every file:line the index cites was checked against the line it points at.
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.
