Service account

Unlike normal users, service account is used by processes inside a pod to contact the Kubernetes API server. By default, a Kubernetes cluster creates different service accounts for different purposes. In GKE, there are bunch of service accounts that have been created:

// list service account across all namespaces
# kubectl get serviceaccount --all-namespaces
NAMESPACE     NAME                         SECRETS   AGE
default       default                      1         5d
kube-public   default                      1         5d
kube-system   namespace-controller         1         5d
kube-system   resourcequota-controller     1         5d
kube-system   service-account-controller   1         5d
kube-system   service-controller           1         5d
project1      default                      1         2h

Kubernetes will create a default service account in each namespace, which will be used if no service account is specified in pod spec during pod creation. Let's take a look...
