We’re evaluating switching to using the k8s agent stack, and it would be very helpful to able to customize the labels applied to the jobs that are submitted into k8s on a per step basis. Specifically I’m hoping to leverage this along with kube-state-metrics to get job durations for specific labels and highlight these in a dashboard. (currently the job labels are just the uuids and optionally agent tags, but that’s too generic). It seems like this could be implemented in a similar way to PodSpecPatch agent-stack-k8s/internal/controller/config/config.go at 8eb53d61131a90232641b38e958bb3836faab615 · buildkite/agent-stack-k8s · GitHub but maybe there’s some other way that I’m not seeing. Thanks!
Hi @nfulwiler ,
Welcome to the Buildkite Support Community! 
Thanks for the feedback. Yes you are right, the current job labels currently cannot be customised. I think our agent stack maintainers would appreciate to hear about this feedback and learn more about your use case. I suggest to raise this feedback here Issues · buildkite/agent-stack-k8s · GitHub.
Cheers!
