Install MetalLB Operator and configure IP pools (3 options)

MetalLB provides LoadBalancer Services on bare metal. On this server (<public-ip>/26), all three options are documented: Option 1 (additional IP), Option 2 (NodePort fallback without MetalLB), Option 3 (internal software bridge).

1Install MetalLB Operator: Ecosystem → Software Catalog → Operators → MetalLB Operator (namespace: metallb-system)

2Create MetalLB CR and wait for Running status

3Option 1 external, additional IP:

→ create IPAddressPool with additional IP as /32, L2Advertisement on eno2

4Option 2 NodePort, no MetalLB needed:

→ create services as NodePort → access via <public-ip>:<NodePort>

5Option 3 internal, software bridge:

→ IPAddressPool in private subnet → reachable only from VMs on the node

6All three options documented in Commands/YAML tab — choose based on availability
