OpenShift API Load Balancer

Dedicated Nginx-based load balancer (okd-lb) that manages entry for the OKD cluster API and ingress traffic.

Core Architecture

• Software: Nginx is the dedicated Kubernetes API load balancer server.
• Deployment: Runs as a Podman container on the desktop-server host.
• Networking (Macvlan): Uses Podman's macvlan driver to obtain a dedicated IP (192.168.1.20) on the LAN. This avoids using the desktop-server IP and simplifies DNS mapping for api, api-int, and apps.

Procedures

Execute these commands from the okd/ directory:

• Create/Start: make create-lb (deploys the Nginx container and macvlan network).
• Destroy: make destroy-lb.

Reference

• Service Mapping: references/ports.md (6443, 22623, 80, 443).
• Hardcoded IP: 192.168.1.20. Ensure an A-record exists with the DNS server for this IP.
• Interface: Requires eno1 on the host to support the macvlan network.
