@md5 nice! Been meaning to add this but haven't had time. Need to test it out but looks pretty straightforward.

Great!

/me should suggest to add @md5 as maintainer to this and the nginx-proxy repos

Is there a sample somewhere on how to use labels in a template? I somehow can not get it to work

[tompson]

The problem is that the labels generated by compose are looking like

 com.docker.compose.service

How do you access them in the template?

I believe index .Labels "com.docker.compose.service" should work. (Update: corrected from .Env.Labels to .Labels)

Sorry if this is the wrong place to ask. How would you use a label such as "com.docker.compose.service" in as part of a $fieldPath with a groupBy or where?

where . "Labels.com.docker.compose.service" "web"

[md5]

@trnubo I don't think it's going to be possible to do that right now. I also think it would be tricky to get right.

Adding groupByLabel and whereLabel functions might not be the worst idea, although it would balloon pretty quickly if you add *Label variants of all the existing where* and groupBy* functions.

@trnubo Take a look at #143

For the case you mentioned, you could do this:

whereLabelValueMatches . "com.docker.compose.service" "^web$"
