I'm developing a service running in Google Kubernetes Engine and I would like to use Google Cloud functionality from that service. I have created a service account in Google Cloud with all the necessary roles and I would like to use these roles from the pod running my service.
I have read this: https://cloud.google.com/kubernetes-engine/docs/tutorials/authenticating-to-cloud-platform and I was wondering if there is an easier way to "connect" the two kinds of service accounts ( defined in Kubernetes - defined in Google Cloud IAM ) ?
Thanks
I don't think there is any direct link. K8s service accounts are purely internal. You could try granting GIAM permissions to serviceaccount:name but that seems unlikely to work. More likely you would put the Google SA credentials in a secret and then write an RBAC policy giving your K8s SA read access to it.
