# Configuration

The `server.cfg` gets created on the fly and gets filled with the enviroment variable starting with `CVAR_`. 
So for example to set the RCON password set the enviroment variable `CVAR_RCON_PASSWORD=password123`. 
Try to avoid variables with the word `CVAR_` and avoid `=` in it.

A list of available cvars can be found [here](https://developer.valvesoftware.com/wiki/List_of_L4D2_Cvars).
