Add ENV Variable to Enable RCON and set RCON port about palworld-server-docker

[xHyperElectric]

I would love to be able to edit any value in the "Pal/Saved/Config/LinuxServer/PalWorldSettings.ini" file, but I'm not sure the best way to do it. Maybe with some guidance, I could submit a PR. Would the best way to handle it just be cd /.../Pal/Saved/Config/LinuxServer/ and something like: sed -i 's/RCONEnabled=False/RCONEnabled=true/' PalWorldSettings.ini?

@xHyperElectric Probably just sed the RCONEnabled in the DefaultPalServerSettings.ini and after all the changes have been made, copy it to the PalServerSettings.ini in /.../Pal/Saved/Config/LinuxServer/

[xHyperElectric]

What would be the best way to allow all of the settings in PalWorldSettings.ini to be changed in the docker file?

[thijsvanloef]

@xHyperElectric Feel free to open a PR even if you are unsure, we can always take a look at it together :)

[thijsvanloef]

@xHyperElectric most user friendly way would be via environment variables

[xHyperElectric]

So is it practical to make an environment variable option for all 62 options?

[thijsvanloef]

@xHyperElectric no not really practical, that is partly the reason i've yet to work on it, because there isn't really any other "user friendly" way

[xHyperElectric]

I think the best way to do it is to add a second Volume for Server Config Storage and have the PalWorldSettings.ini file in there and it overwrites the one in /.../Pal/Saved/Config/LinuxServer/. I think it's recommended to use a bind-mount for this but I am by no means a docker expert.

On theorizing, it may be possible to dynamically search for environment variables based off DefaultPalServerSettings.ini

For example, given this setting found in DefaultPalServerSettings.ini, bEnablePlayerToPlayerDamage, check if a value is in B_ENABLE_PLAYER_TO_PLAYER_DAMGE, and if so, write to PalServerSettings.ini

This would require generating a PalServerSettings.ini on init. You could loop through all given settings in DefaultPalServerSettings.ini using regex, then see if the given setting has a value in the environment converting the setting string from camelCase to SNAKE_CASE, and then write each setting as you loop to PalServerSettings.ini, defaulting to the default value if the environment variable isn't present.

This is unreal engine, meaning https://docs.unrealengine.com/5.2/en-US/configuration-files-in-unreal-engine/ applies.
As such ("Override Configuration from the Command-line" section), you are able to override specific values via commandline

Even better, need to figure out the right syntax for palworld-specific ini settings
