LinuxX64 - NullReferenceException

[tofi92]

Hi, I'm trying to dockerize this server and on startup I get a NullReferenceException:

Dockerfile:

# syntax=docker/dockerfile:1
FROM mcr.microsoft.com/dotnet/runtime AS base
WORKDIR /app
RUN /bin/bash -c 'apt-get update'
RUN /bin/bash -c 'apt-get install -y curl wget unzip'
RUN /bin/bash -c 'curl -s https://api.github.com/repos/TastyLollipop/OpenWorld/releases/latest \
| grep "browser_download_url.*linuxX64.zip" \
| cut -d : -f 2,3 \
| tr -d \" \
| wget -qi -'
RUN /bin/bash -c 'unzip linuxX64.zip'

ENTRYPOINT ["dotnet", "Open World Server.dll"]

The linuxX64.zip does not contain a "Server Settings.txt" and no "World Settings.txt" - should I include/generate those?

Those two files do get generated by the program when It boots. Following what the console log says, those two files should have been generated at startup. Can you verify that's the case? If It is, please check that the file formatting is correctly applied. Could you also tell what distro are you using for the host? And If you have managed to create a server in the past?

[tofi92]

I included both files (from the windows download) and added them to the container - no difference. Host OS is Debian 10. Starting a server on the host works fine.

Yeah... so this isn't going to work unless you launch it with an active tty. The app runs an interactive cli.

Use docker run -itd

Edit your entrypoint to launch in screen (gross):

screen -S openworld /root/.dotnet/dotnet /openworld/Open\ World\ Server.dll
