[Question] How to declare custom label

[WorldTeacher]

I am once again testing how to automate windows builds using actions.
I have added this to the ENV:
GITEA_RUNNER_LABELS = ubuntu-latest:docker://catthehacker/ubuntu:act-22.04,ubuntu-22.04:docker://catthehacker/ubuntu:act-22.04,ubuntu-20.04:docker://catthehacker/ubuntu:act-20.04,windows-2022:docker://mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2022

but no matter what I try, I only get these labels: ubuntu-latest ubuntu-22.04 ubuntu-20.04

How can I add a custom label that uses the provided image (assuming I can pull it in the Docker-in-Docker approach, unRaid is unable to download the image and gives this error:

docker pull mcr.microsoft.com/windows/servercore:ltsc2022-amd64   
ltsc2022-amd64: Pulling from windows/servercore
2c91985a0408: Pulling fs layer 
13a330a51786: Pulling fs layer 
image operating system "windows" cannot be used on this platform: operating system is not supported

Any help is appreciated

Declaring custom labels only worked during registration in older versions of the act runner. In the meantime they added the option to specify labels directly in the config. I now adjusted the config of the docker image to support this as well. Customizing labels vial GITEA_RUNNER_LABELS should work now as expected.
