The sidecar is using Google Cloud Client Library for Golang, which in turn use a library called Application Default Credentials (ADC). ADC allows to pass credentials using GOOGLE_APPLICATION_CREDENTIALS environment variable,...

Also note that you might have to specify --stackdriver.generic.location="some-location-maybe-your-datacenter-name" --stackdriver.generic.namespace="K8S-cluster-name" parameters for the sidecar, so that metrics are created using [generic_task](https://cloud.google.com/monitoring/api/resources#tag_generic_task) monitored resource.

Take a look at https://stackoverflow.com/questions/47021469/how-to-set-google-application-credentials-on-gke-running-through-kubernetes , there is also example in the official GCP docs as well - https://cloud.google.com/kubernetes-engine/docs/tutorials/authenticating-to-cloud-platform#step_4_import_credentials_as_a_secret
