Just out of curiosity, can I do anything about this? I mean, my local

gcloud

has been setup accordingly and doesn't complain anymore but Pulumi executions do:

pulumi:pulumi:Stack (my-stack):
    W0829 14:00:19.388176   16096 gcp.go:120] WARNING: the gcp auth plugin is deprecated in v1.22+, unavailable in v1.25+; use gcloud instead.

@gorgeous-country-43026 this is coming from the Pulumi provider yes. Are you building your own kubeconfig?

No, it's been generated by gcloud. Or well, that version did not have the correct new auth mechanism in place so I put it there according to Google documentation which removed this notification when using kubectl
