Request from a specific IP pool¶

When multiple IP addresses are configured to the system, you can request assignment from a specific IP address pool.

Caution

Do not use the private IP of the master node to configure IP address pools, as admin function of the MKE web UI will become inaccessible as a result.

Add the metallb.universe.tf/address-pool annotation to the service with the name of the IP address pool as the annotation value:

apiVersion: v1
kind: Service
metadata:
  name: nginx
  annotations:
    metallb.universe.tf/address-pool: <IP-address-pool-name>
spec:
  ports:
  - name: http
    port: 80
    protocol: TCP
    targetPort: 80
  selector:
    app: nginx
type: LoadBalancer

On creation, the service is assigned an external IP address from the indicated IP address pool.

Verify the IP address assignment:

kubectl get svc

Example output:

NAME         TYPE           CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
kubernetes   ClusterIP      10.96.0.1      <none>        443/TCP        76m
nginx        LoadBalancer   10.96.183.55   52.205.10.0   80:35328/TCP   9s
