Service Account
A service account provides an identity for processes that run in a pod. Pods that want to interact with the API Server will authenticate with a particular service account. By default, in absence of specific configuration, the pods will authenticate as the default service account in the namespace they are running in. Service accounts are rendered in logs using the following pattern: "system:serviceaccount:namespace:account-name (e.g. "system:serviceaccount:blue:default).

Default Service Account
Each namespace comes with a default service account:
