RoleBinding

RoleBinding in Kubernetes is used to assign a Role or ClusterRole to a specific user, group, or service account within a given namespace (or across the entire cluster for ClusterRole). It binds the permissions defined in a Role or ClusterRole to the users or service accounts, enabling them to perform specific actions on the resources defined by the Role. RoleBindings are essential in Kubernetes' Role-Based Access Control (RBAC) system, as they determine which entities can access and perform actions on the resources in the cluster.

Use Case of RoleBinding -

• Granting Permissions to Users
• Service Account Access
• Access Control Management
• Enforcing Security Policies
