A blueprint for safely removing Advanced Cluster Management from an OpenShift cluster

OpenShift Remove Node Blueprint¶

This blueprint orchestrates the safe removal of nodes from an OpenShift cluster, ensuring proper workload evacuation and resource cleanup. It manages the complete node removal process while maintaining cluster stability.

Requirements¶

Cluster State¶

Sufficient capacity on remaining nodes
No critical workloads on target node
Valid node drain options
Cluster admin access

Infrastructure¶

Active cluster connection
Working cluster networking
Valid kubeconfig
Node management access

Usage¶

Select this blueprint from the cluster management menu when you need to remove nodes from your cluster. Common scenarios include:

Cluster downsizing
Hardware maintenance
Node replacement
Infrastructure updates
Resource reallocation

Verification¶

Before and after node removal, verify: - Workload migration status - Remaining cluster capacity - Resource availability - Node list accuracy

Removal Process¶

The blueprint executes these tasks in sequence: 1. openshift-cluster-remove-node: - Cordons target node - Drains workloads - Removes node from cluster - Updates cluster configuration
