Milvus RBAC Explained: Secure Your Vector Database with Role-Based Access Control

This post elaborates on Milvus's Role-Based Access Control (RBAC) system, detailing its core components (Resource, Privilege, Privilege Group, Role, User) and the hierarchical relationship between them. It explains the authorization flow within Milvus, covering authentication, role assignment, and privilege verification. The post provides practical guidance on configuring RBAC, including enabling authorization in Docker Compose and Helm charts, initializing the root user, and performing core operations such as creating users, roles, privilege groups, granting/revoking privileges and roles, and inspecting access. A specific example demonstrates how to design access control for a RAG system by defining roles and privileges for different actors like administrators, ingestion services, and search services.
