Generate labels with regex

Hello,
I have found a docker promtail configuration which generate some labels for each containers: here

As mentioned in the docs, I tried to used alloy instead. So I converted the the promtail config using alloy convert. However I cannot find the generated labels in loki. I can’t find where to change in order to fix it.

Here is the converted alloy config

can you post the content of your config.alloy here?
