# FeatherWings

> FeatherWings is the Go daemon that runs game servers in Docker containers on each node, with an HTTP API, a console websocket and a built-in SFTP server.

Source: https://featherpanel.com/docs/wings/

FeatherWings runs on every machine that hosts game servers. The panel stores what a server should be; Wings makes it
happen on the node. It:

- creates and runs each server in its own Docker container, and runs the install script of its [spell](https://featherpanel.com/docs/spells);
- exposes an HTTP API on port `8080` that the panel calls, and a websocket for the live console and stats;
- serves server files over its own SFTP server on port `2022`, with the same credentials users have on the panel;
- makes server backups, node backups and server transfers between nodes.

It is written in Go and is a single binary, `featherwings`, managed by the `featherwings` systemd unit. The APT package
also adds a `wings` symlink for older scripts.
