Kubernetes roles and bindings

Role-Based Access Control is only available in Portainer Business Edition.

When managing a Kubernetes environment with Portainer, the Role-Based Access Control (RBAC) configuration is based on two components:

• Kubernetes' cluster roles and namespace roles (which restrict access to Kubernetes itself)

• Portainer's authorization flags (which restrict access to Portainer's functionality)

The following tables provide a reference for how our Portainer roles map to capabilities within Kubernetes.

Role Allocations
