A task to remove Advanced Cluster Management (ACM) from an OpenShift cluster

OpenShift Node Removal Task¶

This task manages the safe removal of a node from an OpenShift cluster. It handles proper workload draining, node cordoning, and cleanup of cluster resources associated with the node.

Requirements¶

Cluster Access¶

Administrative access to OpenShift cluster
Valid kubeconfig configuration
Cluster-admin privileges
Node management permissions

Node State¶

Node should be identified for removal
Workloads should be able to be rescheduled
Sufficient cluster capacity for workload migration

Usage¶

Basic Node Removal¶

# Apply node removal task
drpcli machines tasks add <machine-uuid> openshift-cluster-remove-node

# Monitor node status
oc get nodes

Removal Process¶

Cordons node to prevent new workloads
Drains workloads with:
Force flag for stuck pods
Deletion of local data
Respect for pod disruption budgets
Removes node from cluster
Updates cluster configuration
