K8s-config-connector: CRD for compute subnetworks is missing metadata_fields in the log config for custom metadata

[dustin-decker]

Describe the feature or the resource that you want.

I would like to be able to specify metadata_fields when metadata is set to CUSTOM_METADATA to include GKE fields that make the flow logs k8s-aware.

Hi @dustin-decker thank you for the feature request, we have noted it and will look into prioritizing it an upcoming release.

Hi @dustin-decker, can you comment on whether this request is a nice-to-have, a pain point, or a blocker?

[dustin-decker]

I'd categorize it as a nice-to-have and a pain point.

Flow logs for GKE nodes aren't very useful unless they have the metadata to identify the workload involved. The feature has been published for a few months, but doesn't seem well-supported. I tried adding it to terraform, but we got stuck on what appears to be an API bug: https://github.com/GoogleCloudPlatform/magic-modules/pull/3603 (b/162771344).

[dustin-decker]

filterExpr is another field that was added at the same time which would be nice to see supported.

[jcanseco]

Gotcha, thanks for elaborating in detail!

[dustin-decker]

Received recommendations from the API team on handling the update quirks in https://github.com/GoogleCloudPlatform/magic-modules/pull/3603.

[dustin-decker]

The terraform provider now includes this feature: https://github.com/hashicorp/terraform-provider-google/releases/tag/v3.37.0
From: https://github.com/GoogleCloudPlatform/magic-modules/pull/3603

Thanks for your contributions @dustin-decker! We'll work on bringing them into KCC in the coming weeks.

@dustin-decker , these fields should now be supported as of our 1.21.0 release.
