Glass UI Helm Chart

The Glass UI Helm chart deploys the control plane services for SPOG, providing the web interface, authentication, authorization, and cluster coordination capabilities.

Deployment Context

Glass UI deploys in the control plane cluster alongside the CloudControl controlplane chart. It runs in the controlplane namespace (configurable) and serves as the central hub for all Glass Instrumentation deployments.

UI - Vue 3 web frontend providing the Glass user interface

Authentication & Authorization

auth-users - User authentication service supporting Static, LDAP, and OIDC identity providers
policy - REGO-based authorization engine for fine-grained access control based on cluster labels and user attributes

Service Discovery & Routing

centerMiddleware - Service discovery and cluster routing, maintaining the registry of connected user planes
centerServiceMultiplexer - Multi-cluster call routing, forwarding requests to the appropriate user plane clusters

Configuration Services

globalConfigDashboards - Dashboard configuration management service
globalConfigNavigation - Navigation menu configuration service

State & Event Management
