Rust Auto Wipe

Description

An application made in Go (latest version works) for Rust servers operating with Pterodactyl (latest API version works). This application automatically wipes server(s) based off of cron jobs. The program is aimed to be as flexible as possible. With that said, there are many features including the following.

• Allow rotating of world settings (map/level, world size, and world seed).
• Allow automatically changing the host name on each wipe with format support (including option replacements like {day_two} and {month_two}).
• Deletion of files with the option to except specific types (e.g. don't delete player data such as states, identities, tokens, and more).
• A flexible configuration and uses a cron job system (support for multiple cron jobs per server).
• Support for retrieving servers automatically from Pterodactyl API.
• Pterodactyl egg variable overrides to allow others to change these settings without having access to the application's file system.
• Pre and post wipe hooks (sends POST data to specific endpoints that can be used for Discord web hooks for example).

Note - This is only tested on Linux. However, technically it should work for Windows as well.

Command Line Usage

The below is the command line usage from the help menu for this program.

Help Options
        -cfg= --cfg -cfg <path> > Path to config file override.
        -l --list > Print out full config.
        -v --version > Print out version and exit.
        -h --help > Display help menu.

Configuration

All configuration is done inside a config file on disk via JSON or through environmental variable overrides. The default config path is /etc/raw/raw.conf and may be changed via the -cfg command line flag.

Any wipe-specific configuration at the top-level of the configuration is used as the default values for each server. Each server may override these by specifiying the same key => value pairs inside of the server array.

When the program is ran, but no configuration file is found, it will attempt to create the file (likely requiring root privileges by default if trying to create inside of /etc/, however). The below are all JSON settings along with their default values, but with added comments. Remember that JSON does not support comments. Therefore, copying the below contents with comments will result in errors. This is why it's recommended to allow the program to create a default configuration file.

Note - When writing to the default file after creation, it will try to make the JSON data pretty (AKA pretty print by idents).

Environmental Overrides With Auto-Added Servers

There are environmental overrides for servers that are added from the Pterodactyl API. This allows you to distribute access easier from within the Pterodactyl panel itself.

With that said, the file data/egg-rustraw.json file in this respository is an exported egg that has the standard Rust egg settings from Pterodactyl along with the additional RAW settings. If you import this egg into Pterodactyl under Rust and change the server's egg in the administrator settings, it will easily migrate all existing variable settings over including the Rust egg's default variables.

Each variable is also parsed as a string within the application's code. For true/false, use the 1/0 integers respectfully.

The following is a list of environmental names you can create variables within Pterodactyl Nests/Eggs for overrides.

• RAW_ENABLED - Enabled override.
• RAW_PATHTOFILES - Path to files override.
• RAW_TIMEZONE - Timezone override.
• RAW_CRONMERGE - Cron merge override.
• RAW_CRONSTR - Cron string override (this is a special case, cron string(s) can be a single string or a string array as a JSON string (e.g. ["*/5 * * * *", "*/2 * * * *"])).
• RAW_DELETEMAP - Delete map override.
• RAW_DELETEBP - Delete blueprints override.
• RAW_DELETEDEATHS - Delete deaths override.
• RAW_DELETESTATES - Delete states override.
• RAW_DELETEIDENTITIES - Delete identities override.
• RAW_DELETEFILESMERGE - Whether to merge additional deletion of files override (top-level config and server-specific).
• RAW_DELETEFILES - Additional files to delete override. (e.g. [{"root": "/server/rust", "files": [".log"]}] as a string).
• RAW_DELETESV - Delete server files/data override.
• RAW_CHANGEWORLDINFO - Change world info override.
• RAW_WORLDINFO - World info override. An array with the map, world size, and world seed. (e.g. [{"map": "Procedural Map", "worldsize": 4000, "worldseed": 9213913}] as a string).
• RAW_WORLDINFOPICKTYPE - Change world info pick type override.
• RAW_WORLDINFOMERGE - Change world info merge override.
• RAW_CHANGEHOSTNAME - Change hostname override.
• RAW_HOSTNAME - Hostname override.
• RAW_MERGEWARNINGS - Merge warnings override.
• RAW_WARNINGMESSAGES - Warning messages override (another special case, this should be a JSON string of the normal warningmessages JSON item). (e.g. [{"warningtime": 5, "message": "{seconds_left} until wipe!"}] as a string).
• RAW_WIPEFIRST - Wipe first override.

Building And Running Project (Manually)

Building the project is simple. We only require git and Go.

# Clone repository.
git clone https://github.com/gamemann/Rust-Auto-Wipe.git

# Change directory to repository.
cd Rust-Auto-Wipe/

# Build using Go into `raw` executable. This will also retrieve needed packages such as Cronv3.
go build -o raw

Using Makefile as described below is my personal recommendation on installing this application for Linux-based systems.

Using Makefile + Systemd (Recommended)

You may also use a Makefile I made to build the application and install a Systemd file.

# Build project (go build -o raw).
make

# Install `rawapp` (/usr/bin/rawapp) and Systemd process.
sudo make install

To have the application run on startup, and/or in the background, you may do the following.

# Reload Systemd daemon (may be needed after install of Systemd service).
sudo systemctl daemon-reload

# Enable (on startup) and start service.
sudo systemctl enable --now raw

# Start service.
sudo systemctl start raw

# Restart service.
sudo systemctl restart raw

# Stop service.
sudo systemctl stop raw

# Disable (on startup) and stop service.
sudo systemctl disable --now raw
