question

I believe you can do this through using the dockerfile.

EXPOSE 3600/tcp
EXPOSE 3600/udp

Here is my dockerfile for my darkrift server example which runs on MPS.

FROM mcr.microsoft.com/dotnet/core/runtime:3.1-buster-slim AS base
WORKDIR /app
FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src


COPY DarkRiftCore.Plugins/DarkRiftCore.Plugins.csproj DarkRiftCore.Plugins/
RUN dotnet restore "DarkRiftCore.Plugins/DarkRiftCore.Plugins.csproj"


COPY GameServer/GameServer.csproj GameServer/
RUN dotnet restore "GameServer/GameServer.csproj"


COPY . .


WORKDIR "/src/DarkRiftCore.Plugins"
RUN dotnet build "DarkRiftCore.Plugins.csproj" -c PlayFab -o /app/build/Plugins


FROM build AS plugins
RUN dotnet publish "DarkRiftCore.Plugins.csproj" -c PlayFab -o /app/publish/Plugins


WORKDIR "/src/GameServer"
RUN dotnet build "GameServer.csproj" -c PlayFab -o /app/build


FROM plugins AS publish
RUN dotnet publish "GameServer.csproj" -c PlayFab -o /app/publish


FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .


RUN mkdir -p /app/publish/Data
RUN mkdir -p /app/publish/Logs


EXPOSE 3600/tcp
EXPOSE 3600/udp


ENTRYPOINT ["dotnet", "GameServer.dll"]
