#kubernetes #auth #serviceaccount #role #rolebinding

Find out what permission a user has in kubernetes cluster?
Try auth can-i to verify your access level.

I found auth can-i helpful when I thought to verify whether one of the pods has access to create another. I mainly used it when airflow tried to create a new pod.

In the Architecture diagram, When a user creates a DAG, they would use an operator like the "SparkSubmitOperator" or the "PythonOperator" to submit/monitor a Spark job or a Python function respectively. To find more details click on below link:
