Service accounts are used to access kubernetes services through APIs by other software programs. For example, a prometheus service to watch the resources matrices etc.

To access the kubernetes we following things

2. token for that service account

Token will then can be used in application to access kubernetes.

kubectl create sa dashboard-sa

Or

kubectl create serviceaccount dashboard-sa

kubectl create token dashboard-sa

(It is assumed that permissions have been assigned to a service account.)
