OpenShift Bootstrap Node Configuration Profile
OpenShift Load Balancer Profile¶
This profile configures HAProxy load balancers for distributing traffic to the OpenShift cluster's control plane and worker nodes. Load balancers are essential for high availability and external access to cluster services.
Requirements¶
- Minimum 2 vCPUs per node
- Minimum 4GB RAM per node
- Minimum 20GB disk space
- Network access to:
- Port 6443 (API Server)
- Port 22623 (Machine Config Server)
- Port 443 (HTTPS Ingress)
- Port 80 (HTTP Ingress)
- Public network accessibility
- Multiple nodes recommended for HA
Usage¶
This profile is automatically applied to load balancer nodes and configures:
# Profile configures:
- Base OS (Photon OS)
- HAProxy installation
- Backend service filters
- Load balancing algorithms:
* Round-robin for API server
* Source-based for ingress routers
Configuration includes health checks and automatic service discovery for cluster nodes.
