# GMOD TTT
GMOD TTT server image, https://hub.docker.com/r/jusito/

## Important
If you use the old image, you should check the environment variables. For example arguments after image name aren't used, use instead `-e SERVER_ADDITIONAL_PARAMETERS=...`.
This readme may not be perfect, if you struggle at some point or you see incorrect informations create an issue at git please.

## Getting Started
### Prepare your server content
1. Create public workshop collection without maps, dummy ID:=123456. Use `-e WORKSHOP_COLLECTION_ID 123456`.
2. Create public workshop collection with maps and add this one to "123456".
3. Do you want every user to load the content automatically? Yes you are done, no `-e WORKSHOP_AUTOLOAD=false`. Remember that "false" mean, that every user has to manually subscribe to your collection. If you don't separate maps / others, every connecting user would load all maps on first connecting. This would be a pain for some.
4. Do your content needs CSS, HL2, HLDM, TF2? Use `-e INSTALL_CSS=true` and/or `-e INSTALL_HL2=true` and so on. Most content will need at least CSS.

### Server config
1. Pick your ports `-e SERVER_PORT=27015 -p 27015:27015/udp` both are always needed. For RCON `[...] -e SERVER_RCON_PASSWORD="verySecure" -p 27015:27015/tcp`.
2. Set environment variables like servername `-e SERVER_NAME="My Server"`, password `-e SERVER_PASSWORD="securepw"` and timezone for cron `-e TZ="Europe/Berlin"`, default short downtime at Sunday 10 o'clock.
3. Choose startmap (can be from workshop collection, even linked) `-e SERVER_DEFAULT_MAP=ttt_rooftops_2016_v1` and max players `-e SERVER_MAX_PLAYERS=20`
4. Get a volume name `-v TTTDev:/home/steam/serverfiles`

### run example without rcon
If you need rcon only sometimes, use ulx with this config.

```
docker run -d \
 -p 27015:27015/udp \
 -e SERVER_PORT=27015 \
 -e INSTALL_CSS=true \
 -e WORKSHOP_COLLECTION_ID=123456 \
 -e SERVER_NAME="My Server" \
 -e SERVER_PASSWORD="securepw" \
 -e SERVER_DEFAULT_MAP="ttt_lttp_kakariko_a4" \
 -v TTTDev:/home/steam/serverfiles \
 --name "MyTTTServer" \
 jusito/docker-ttt:gmod_ttt_debian
```

### run example with rcon
```
docker run -d \
 -p 27015:27015/udp \
 -e SERVER_PORT=27015 \
 -e INSTALL_CSS=true \
 -e WORKSHOP_COLLECTION_ID=123456 \
 -e SERVER_NAME="My Server" \
 -e SERVER_PASSWORD="securepw" \
 -e SERVER_DEFAULT_MAP="ttt_lttp_kakariko_a4" \
 -v TTTDev:/home/steam/serverfiles \
 -p 27015:27015/tcp \
 -e SERVER_RCON_PASSWORD="securePW" \
 --name "MyTTTServer" \
 jusito/docker-ttt:gmod_ttt_debian
```

## Environment Variables
Because you will most likely use many environmental variables, I recommend a env list. Instead of `-e VARNAME="VALUE 1"` write one additional text file:

TTT.env:

```
VARNAME=Value 1
SERVER_NAME=My Hood
SERVER_PASSWORD=Secure_PW
```

## File Locations
### Volumes
/home/steam/serverfiles

### Other
server.cfg: /home/steam/serverfiles/garrysmod/cfg/gmodserver.cfg
hostname, password, rcon password, voice enabled are managed / will be overwritten

## server config
http://ttt.badking.net/config-and-commands/convars
https://wiki.garrysmod.de/server.cfg

Path in container is:
docker cp "your server.cfg path" CONTAINER:/home/steam/serverfiles/garrysmod/cfg/gmodserver.cfg


## Additional
- Debian Buster, one dependency is missing: https://packages.debian.org/search?keywords=lib32tinfo5
- Alpine, steamcmd doesn't like musl

### TODO
#### image improvements
* volume for steam workshop
* volume for other games
* volume for gmod config (data folder)
* AppArmor Profile

#### image config, description needed
* scrds doesn't like different internal / external ports (thats why no ports are exposed)
* health check -> details

### For local usage
navigate to directory with readme.md
bash test/testBuild.sh (sh doesn't like pipefail, escape if you want to use sh)
