Load Balancer Node Names

This parameter defines the list of hostnames for HAProxy load balancer nodes in the OpenShift cluster. Load balancers distribute traffic to cluster services and provide the entry point for external access.

Requirements

  • Must follow DNS hostname standards
  • Must be unique within cluster
  • Must use cluster domain suffix
  • Should follow consistent naming pattern
  • At least one required, more for HA

Usage

Default naming pattern: 

# Standard format
lb.{{.Machine.Name}}.{{.ParamExpand "openshift/cluster-domain"}}

# Example with cluster 'prod' and domain 'example.com':
- lb.prod.example.com

# Multiple load balancers for HA:
- lb1.prod.example.com
- lb2.prod.example.com

Notes: - Critical for cluster access - Used for API and application traffic - Referenced in DNS configuration - Affects cluster accessibility - Should be placed for optimal network access
