openshift/role¶

OpenShift cluster agent configuration path

OpenShift Node Role¶

This parameter defines the role a node will play in the OpenShift cluster. Each role has specific responsibilities and requirements within the cluster architecture.

Requirements¶

Must be one of the defined role values
Role assignment must align with hardware requirements
Node count must meet minimum requirements for role type

Usage¶

Available roles:

bootstrap     # Temporary node that initializes the cluster
controlplane  # Control plane node running cluster control services
worker        # Worker node running application workloads
load-balancer # HAProxy load balancer for cluster traffic
resource      # A node that is reserved for use by the built cluster (IPI-Only)

Role requirements: - bootstrap: One node only, temporary (UPI-Only) - controlplane: Three nodes recommended for HA - worker: Minimum one node, scale as needed - load-balancer: Minimum one node, multiple for HA (UPI-Only) - resource: A node that is reserved for use by the built cluster (IPI-Only)

Notes: - Bootstrap node is automatically converted to worker after cluster initialization (UPI-Only) - Control plane nodes should be identical in specifications - Worker nodes can have varying specifications based on workload needs - Load balancers should be placed for optimal network connectivity (UPI-Only) - Resource nodes are used for additional capacity in IPI clusters
