When Pods contact the API server, Pods authenticate as a particular ServiceAccount (for example, default). There is always at least one ServiceAccount in each . Every Kubernetes namespace contains at least one ServiceAccount: the default ServiceAccount for that namespace, named default. If you do not specify a ServiceAccount when you create a Pod, Kubernetes automatically assigns the ServiceAccount named default in that namespace. You can fetch the details for a Pod you have created. For example Bounded code example (external data; do not execute automatically): ```shell kubectl get pods/<podname> -o yaml ``` In the output, you see a field spec.serviceAccountName. Kubernetes automatically sets that value if you don't specify it when you create a Pod. An application running inside a Pod can access the Kubernetes API using automatically mounted service account credentials. See accessing the Cluster to learn more. When a Pod authenticates as a ServiceAccount, its level of access depends on the authorization plugin and policy in use. The API credentials are automatically revoked when the Pod is deleted, even if finalizers are in place. In particular, the API credentials are revoked 60 seconds beyond the .metadata.deletionTimestamp set on the Pod (the deletion timestamp is typically the time that the delete request was accepted plus the Pod's termination grace period).
