Cluster Registration

In Development (Q4 2026)

This feature is currently in development. Registration workflows described here are subject to change.

Purpose: For platform engineers, describes how to register existing openCenter clusters into a managed fleet.

Registration Flow

  1. Generate registration token on hub cluster
  2. Install fleet agent on spoke cluster using token
  3. Agent connects to hub and reports cluster metadata
  4. Hub registers cluster with labels and group assignments
  5. Fleet operations become available for the registered cluster

Generate Token

opencenter fleet token create \
--cluster-name "prod-us-east-01" \
--labels "environment=production,region=us-east,provider=openstack" \
--ttl 24h

Install Agent

opencenter fleet join \
--hub-url "https://fleet.example.com" \
--token "<registration-token>" \
--cluster-name "prod-us-east-01"

This deploys the fleet agent into the opencenter-fleet-system namespace on the spoke cluster.

Cluster Labels

Labels are used for grouping and targeting:

LabelPurposeExample
environmentDeployment stageproduction, staging, dev
regionGeographic locationus-east, eu-west, ap-south
providerInfrastructure provideropenstack, vmware, baremetal
tierService tiercritical, standard
blueprintActive blueprintfinance, healthcare, telco

Deregistration

opencenter fleet leave --cluster-name "prod-us-east-01"

This removes the agent and unregisters the cluster from the hub. Workloads on the spoke cluster are unaffected.
