Serverconfig via ENV

[frenos]

Allow Serversettings to be set via ENV.

Maybe read ENV-vars and edit configfile before running server?

Can set

• Servername
• Port
• Password
• PlayMode
• AdminSteamId
  via Environement variables.

"Edit configfile before running server". I think a (readonly) volume for a specific config file on the host system should solve this, right? You already mentioned it in your README too.

docker run --name btlserver -v /path/to/host/config:/path/to/container/config frenos/btl44. If the config file exists on the host, the container will use this one, if it does not exists the container will use the embedded config file.

Yes, that was exactly our first thought about that.
If you just want a single customized server that will work fine when the config is writable, but you have to be aware that set environment variables will also write to that config.
I also had a chat with the serveradmin of a gaming community that want to run 6 equal servers with just the hostnames different.

We got the following solution:

• Customized config is mounted to a dummy directory, together with possible custom decks
• Container starts and copies those files over the default server config
• Container sets environment variables in the (copied) config
• Container starts server

The big advantage: I can customize a new base-config with all the great settings I want on my servers, then start n containers and give each one a different servername via separate environment variables.
I think that looks like the most flexible solution for all cases and I will implement this probably tonight or tomorrow.

Sounds good to me.
