Feature Spec

Overview

Open Cluster Management makes it easy for users to create and manage a large number of Kubernetes clusters. The search feature helps users easily find, access, and edit resources in the managed clusters from a central place.

Architecture Diagram

TODO: Add updated architecture diagram here.

Components

Search Operator (repo)

• Deploys, configures, and monitors the components.

Database (repo)

• PostgreSQL 13

Collector (repo)

• Deployed on each managed cluster.
• Discovers Kubernetes resources dynamically and watches for updates.
  • CLI equivalent: oc api-resources
  • CLI equivalent: oc get <resource> --all-namespaces --watch
• Collects and sends data to the indexer every 5 seconds.
• Computes relationships for resources within the cluster.

Indexer (repo)

• Receives data from the collectors and writes to the database.
• Watches resources in the hub cluster (e.g. clusters, applications, policies).
• Computes multi-cluster relationships (ie. Applications).
• Keeps track of activity from connected collectors (heartbeat).

Query API (repo)

• Provides an API to query the data.
• Enforces RBAC, each user will only see resources they have been authorized to access.
