+# docker-garrysmod
+
+A Docker image for running a [Garry's Mod](https://gmod.facepunch.com/) dedicated server, based on [hackebein/docker-srcds](https://github.com/Hackebein/docker-srcds).
+
+This repository is a fork of [Hackebein/docker-garrysmod](https://github.com/Hackebein/docker-garrysmod).
+
+Garry's Mod is a physics sandbox. There aren't any predefined aims or goals. The game gives you the tools and leaves you to play.
+
+The image is automatically built and pushed to:
+
+```text
+git.sh-edraft.de/sh-edraft.de/garrysmod
+```

+- [Further Configuration](#further-configuration)
+
+## Quick Start
+
+Start a basic sandbox server on the default port (`27015`):
+
+```bash
+docker run -it \
+    -p 27015:27015/tcp \
+    -p 27015:27015/udp \
+    git.sh-edraft.de/sh-edraft.de/garrysmod
+```
+
+## Enabling the Steam API
+
+Some features (public server listing, Workshop downloads) require a Steam Web API key.
+
+```bash
+docker run -it \
+    -p 27015:27015/tcp \
+    -p 27015:27015/udp \
+    -e "AUTHKEY=..." \
+    git.sh-edraft.de/sh-edraft.de/garrysmod
+```
+
+Get your `AUTHKEY` from <http://steamcommunity.com/dev/apikey>.
+
+## Public Listing
+
+If you've set `AUTHKEY`, your server is automatically listed publicly. Alternatively, you can register a Game Server Login Token (GLST) manually:
+
+```bash
+docker run -it \
+    -p 27015:27015/tcp \
+    -p 27015:27015/udp \
+    -e "GLST=..." \
+    git.sh-edraft.de/sh-edraft.de/garrysmod
+```
+
+Get your `GLST` from <http://steamcommunity.com/dev/managegameservers> (App ID: `4000`).
+
+## Workshop Collections
+
+Downloading Workshop content requires `AUTHKEY` to be set.
+
+```bash
+docker run -it \
+    -p 27015:27015/tcp \
+    -p 27015:27015/udp \
+    -e "AUTHKEY=..." \
+    -e "WORKSHOPCOLLECTIONID=..." \
+    git.sh-edraft.de/sh-edraft.de/garrysmod
+```
+
+## Custom Server Configuration
+
+Mount your own `server.cfg` into the container:
+
+```bash
+docker run -it \
+    -p 27015:27015/tcp \
+    -p 27015:27015/udp \
+    -v ./server.cfg:/opt/steam/garrysmod/cfg/server.cfg \
+    git.sh-edraft.de/sh-edraft.de/garrysmod
+```
+
+## Example: Trouble in Terrorist Town (TTT)
+
+```bash
+# make sure the server.cfg file exists
+touch ./server.cfg
+
+# start the container
+docker run -it \
+    -p 27015:27015/tcp \
+    -p 27015:27015/udp \
+    -e "AUTHKEY=..." \
+    -e "GAMEMODE=terrortown" \
+    -e "MAP=ttt_minecraft_b5" \
+    -e "WORKSHOP=843519054" \
+    -e "WORKSHOPDL=843519054" \
+    -v ./server.cfg:/opt/steam/garrysmod/cfg/server.cfg \
+    -v ./overlay:/opt/overlay \
+    git.sh-edraft.de/sh-edraft.de/garrysmod
+```
+
+This uses the [TTT Workshop Collection](https://steamcommunity.com/sharedfiles/filedetails/?id=843519054), downloaded both server-side (`WORKSHOP`) and client-side (`WORKSHOPDL`).
+
+## Environment Variables
+

+| `GAMEMODE` | Gamemode to run on server start | `sandbox` |

+## Overlay Folder
+
+You can use an overlay folder to add or overwrite files provided by Steam (e.g. addons, configs, maps) without rebuilding the image:
+
+```bash
+-v ./overlay:/opt/overlay
+```
+
+See [hackebein/docker-srcds: Overlay folder](https://github.com/Hackebein/docker-srcds#overlay-folder) for details.
+
+## Further Configuration
+
+This image inherits all environment variables and options from the parent image. See [hackebein/docker-srcds](https://github.com/Hackebein/docker-srcds) for the full list of available configuration options.
