openshift/network/machineNetwork

IP address blocks for machines in the OpenShift cluster

Machine Network Configuration

This parameter defines the IP address block(s) that will be used for node IP addresses in the OpenShift cluster. This network must be routable both inside and outside the cluster.

Requirements

  • CIDR block(s) must be available in your infrastructure
  • Must not overlap with serviceNetwork or clusterNetwork
  • Must be routable within your infrastructure
  • Must have sufficient IP addresses for all cluster nodes
  • Must be properly configured in your network infrastructure

Usage

Configure one or more CIDR blocks for machine addressing: 

# Default configuration
- cidr: 172.21.0.0/20    # Provides 4094 addresses

# Multiple network example
- cidr: 172.21.0.0/20    # Primary network
- cidr: 172.22.0.0/20    # Secondary network

The machine network is used for: - Node IP addresses - API endpoints - Load balancer addresses - Internal cluster communication
