Service Account

Service Account in Kubernetes provides an identity for processes running in a Pod, allowing them to access the Kubernetes API server. It defines which permissions are granted to the service running in a pod, enabling access control through Role-Based Access Control (RBAC). Service accounts are used to associate a Pod with a specific identity, which can be granted necessary privileges for accessing resources within the cluster, such as secrets, ConfigMaps, or other services.

Use Case of Service Account -

• Pod Authentication
• Access Control
• Automation and Continuous Integration
• Security Management
