Omitting Kubernetes fields in source

[ottramst]

Hey all!

When upgrading from 0.24 to 0.26, we seemed to have lost the option to omit specific fields in the kubernetes_logs source.

In 0.24 it was possible to omit like so:

sources:
  kubernetes_logs:
    type: kubernetes_logs
    namespace_annotation_fields:
      namespace_labels: ""

In 0.26 it gives the next error

"Configuration error.","error":"Invalid field path \"\" for key `sources.kubernetes_logs`"

I would want to avoid implementing a remap for this, because it will just raise the resource cost on the Vector agent in Kubernetes.

Any advice here?

Many thanks!

Hi @ottramst ! This appears to be a regression, thanks for flagging it. I converted this to a bug report here: #15489
