Compatibility with OpenTTD stable releases

[AP-Hunt]

Hi Louis,

First off, thanks for working on this and publishing it. I've wanted to see a Prometheus endpoint in OpenTTD for a long while, but I don't have the relevant language skills or experience of the OpenTTD code base.

I've been able to compile and run a dedicated server from your repo, and successfully get Prometheus metrics from it (on port 10808), and I'd be happy to contribute written guidance on how to do that, and/or the Dockerfile I wrote for it.

I've also been able to run the binary compiled from your repo as a client, connect to the server, and test that the game is playable. This was done from a Linux VM, because I'm a Windows user.

However, I've not been able to get an official 1.10.1 release to be compatible as a client; the multiplayer server browser says "version mismatch". I've made sure to compile it with make VERSION='1.10.1' so that the version numbers match, and I've also made sure to install the same NewGRF version as the official release (which I find by running openttd.exe --version).

Do you happen to know what it is I'm missing? Or is the best/only way to get this all working to run a client compiled from the same repository?

I appreciate this might well be a throwaway personal project for you, so if you don't have an answer for me, that's absolutely fine.

Regards,
Andy

Hello,

I'm really interested in getting a metrics endpoint for OpenTTD as well.
I managed to compile the project and connect to it but I still don't get any metrics on port 8080.
Maybe you can share some guidance or your Dockerfile @AP-Hunt ?
Thank you :)

Hi @towa,

I got a version working in the end, but it's been a few months now and I can't remember how. I was able to find my Dockerfile and docker-compose.yml, which I've added below. Hopefully they'll help you get it running for yourself.

Hej @AP-Hunt,
Thanks a lot! It's working now.
All that was missing was the following line: sed -i 's/127.0.0.1:10808/0.0.0.0:10808/g' src/metrics.cpp.
I made a fork of the /r/openttd docker image here: https://github.com/towa/docker_openttd

Cheers
