Subscription channel for Red Hat Advanced Cluster Management operator

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
