Space station 14 и бомже-хост

Загорелась идея поднять сервер SS14, но на очень дешёвом хосте, да и ещё и со своей сборкой. Недолго думая взял машину из под OpenTTD, где ещё хоститься и VPN с ботом, и начал мудрить.

Начнём с ингридиентов:

• Форк русского репозитория
• «Лучший бюджетный хостинг» — по словам хоста
• Куча времени

Первые проблемы

Всё началось с хоста доставки контента. Если вы пришли из Garry’s Mod, то SS14 даст вам по лицу со своим zip и постоянными ребилдами, если вы изменили одну строку.

Спасибо GitHub, что можно настроить action. Имеем скрипт, который сам всё билдит и заливает на сервер через SFTP:

name: Publish

concurrency:
  group: publish

on:
  workflow_dispatch:
  schedule:
    - cron: '0 1 * * *'

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v2
      with:
        submodules: 'recursive'
    - name: Setup .NET Core
      uses: actions/setup-dotnet@v3
      with:
        dotnet-version: 6.0.100

    - name: Get Engine Tag
      run: |
        cd RobustToolbox
        git fetch --depth=1
    - name: Package all
      run: |
        Tools/package_server_build.py -p win-x64 linux-x64 osx-x64 linux-arm64
        Tools/package_client_build.py
    - name: Update Build Info
      run: Tools/gen_build_info.py

    - name: Shuffle files around
      run: |
        mkdir "release/${{ github.sha }}"
        mv release/*.zip "release/${{ github.sha }}"
    - name: Upload files to mothership
      uses: appleboy/scp-action@master
      with:
        host: ${{ secrets.BUILDS_HOST }}
        port: ${{ secrets.BUILDS_PORT }}
        username: ${{ secrets.BUILDS_USERNAME }}
        password: ${{ secrets.BUILDS_SSH_KEY }}
        source: "release/${{ github.sha }}"
        target: ${{ secrets.BUILDS_PATH }}
        use_insecure_cipher: true
        strip_components: 1

secrets.N — добавляются в Enviroment (настройки репозитория).

Учтите, что клиент в любом случае будет перекачивать весь клиентский билд заново, даже если вы изменили только 1 строку/спрайт и т.п.

Предупреждение: если вы захотели добавить спрайт, то лучше использовать уникальное имя, иначе игра подтянет уже существующий у игрока контент.

Хостинг сервера

Взял самый дешёвый тариф за 150р/месяц

2 ядра (AMD Epyc?)

4GB RAM

30GB ROM

100Mbit/sec канал

С холодного старта сервер ест ~10% CPU

После захода 1-3 игроков ~35% CPU

Зачем такая слабая машина? «Тестируем сервер на пределе возможностей». Если сервер выдержит примерно ~20-30 онлайна, то значит SS14 можно будет хостить на этой дешманской печке, ну или взять тариф подороже.

Сам конфиг сервера:

# Welcome to the example configuration file!
# Remember that if this is in bin/Content.Server or such, it may be overwritten on build.
# Consider copying it and using the --config-file and --data-dir options.

[status]
# The status server is the TCP side, used by the launcher to determine engine version, etc.
# To be clear: Disabling it makes the launcher unable to connect!
enabled = true

# This is the address and port the status server binds to.
# The port is by default set based on net.port so it will follow what you set there.
# bind = "*:1212"

# This is the address of the SS14 server as the launcher uses it.
# This is only needed if you're proxying the status HTTP server -
#  by default the launcher will assume the address and port match that of the status server.

[build]
# *Absolutely all of these can be supplied using a "build.json" file*
# For further information, see https://github.com/space-wizards/space-station-14/blob/master/Tools/gen_build_info.py
# The main reason you'd want to supply any of these manually is for a custom fork and if you have no tools.

# Useful to override if the existing version is bad.
# See https://github.com/space-wizards/RobustToolbox/tags for version values, remove the 'v'.
# The value listed here is almost certainly wrong - it is ONLY a demonstration of format.
# engine_version = "0.7.6"

# This is where the launcher will download the client ZIP from.
# If this isn't supplied, the server will check for a file called "Content.Client.zip",
#  and will host it on the status server.
# If that isn't available, the server will attempt to find and use "../../Resources" and
#  "../../bin/Content.Client" to automatically construct a client zip.
# It will then host this on the status server.
# Note that these paths do not work on "FULL_RELEASE" servers.
# FULL_RELEASE servers expect to be used with a specific "packaged" layout.
# As such, whatever script you're using to package them is expected to create the ZIP.
download_url = "https://srv0.troit5ky.ru/cdn/a6f51b48dbb207a2b3c5cb90386a77416757e385/SS14.Client.zip"

# Optional in any case and automatically set if hosting a client ZIP.
# This hash is an example only.

[auth]
# Authentication (accounts):
# 0 = Optional, 1 = Required, 2 = Disabled
# Presumably do require authentication on any public server.
mode = 1

# If true, even if authentication is required, localhost is still allowed to login directly regardless.
# allowlocal = true

# You should probably never EVER need to touch this, but if you need a custom auth server,
# (the auth server being the one which manages Space Station 14 accounts), you change it here.
# server = https://central.spacestation14.io/auth/

Ко всем основным параметрам уже есть пояснения и примеры.

Предупреждение: если захотите отыскать другие переменные, то придётся лезть в код самого CCVar, который написан на C#.

P.S.

Если из этого выйдет что-то интересно, то буду дополнять/писать статьи с новыми проблемами и их решениями.
