Multi-cluster boot-strapping via federated authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cluster management systems are inefficient and ineffective in providing user access to multi-cluster and multi-tenant environments, requiring manual creation of user accounts and different interfaces for each computing cluster, leading to a decentralized and error-prone process.
Innovation Solution
The system bootstraps a primary computing cluster to secondary clusters and binds user roles, allowing users to access multiple clusters via a centralized interface using their credentials, establishing temporary and persistent connections while impersonating cluster roles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual user account creation is performed for each computing cluster, then user access control is achieved, but the process becomes time-consuming and error-prone
Solution Approach 1:
The system enables self-service by allowing users to automatically authenticate across multiple clusters using their existing cloud provider credentials. The federated authentication mechanism eliminates the need for manual account creation in each cluster, as users can log in once through the portal and access multiple clusters automatically without repeated manual setup.
Solution Approach 2:
The user portal serves multiple functions: it provides centralized access to multiple computing clusters, handles authentication for different clusters, and manages user permissions across the entire multi-cluster environment. This universal portal replaces the need for separate manual account creation processes for each individual cluster.
2Reliability
If separate interfaces are provided for each computing cluster, then cluster-specific access control is achieved, but system complexity increases
Solution Approach 1:
A single universal user portal is designed to access multiple different computing clusters, replacing the need for separate cluster-specific interfaces. The portal maintains cluster-specific access control through centralized authentication while presenting a unified, simplified interface for users to access any connected cluster.
Solution Approach 2:
The user portal acts as an intermediary layer between users and the individual computing clusters. It handles authentication and permission management centrally, then facilitates access to the appropriate cluster based on user credentials and permissions, eliminating the need for users to directly interact with multiple separate interfaces.
3Adaptability or versatility
If decentralized cluster management is implemented, then cluster independence is achieved, but user access efficiency decreases
Solution Approach 1:
The user portal serves as a centralized intermediary that coordinates access to multiple independently managed clusters. It maintains the independence of individual clusters while providing efficient centralized access control, authentication, and user management across the entire multi-cluster environment.
Solution Approach 2:
The universal portal provides efficient access to multiple clusters without requiring users to interact with each cluster's management system directly. It consolidates access control and authentication functions, improving productivity while preserving cluster independence through the federated authentication architecture.

AI summary
Disclosed herein are system, method, and computer program product embodiments for multi-cluster boot-strapping. In some embodiments, a server residing on a primary computing cluster receives a first request to establish a temporary connection between the primary computing cluster and a secondary computing cluster. The server establishes the temporary connection between the primary computing cluster and the secondary computing cluster using the first set of credentials. Furthermore, the server receives a second request to establish a persistent connection between the primary computing cluster and the secondary computing cluster. The server establishes the persistent connection by transmitting a third request comprising the configuration settings to the secondary computing cluster thereby causing the secondary computing cluster to generate a second set of credentials corresponding to the primary computing cluster. The server receives and stores the second set of credentials.
