Since I'm not able to write comments, will add all details and path here.
I used following page for setting up a Metal loadbalancer.
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.9.6/manifests/namespace.yaml
kubectl apply -f
https://raw.githubusercontent.com/metallb/metallb/v0.9.6/manifests/metallb.yaml
# On first install only
kubectl create secret generic -n metallb-system memberlist --from-literal=secretkey="$(openssl rand -base64 128)"
You can verify an installation by running:
kubectl get all -n metallb-system
NAME READY STATUS RESTARTS AGE
pod/controller-64f86798cc-cfb5t 1/1 Running 0 8m35s
pod/speaker-8vwhc 1/1 Running 0 8m35s
pod/speaker-zs8zk 1/1 Running 0 8m35s
NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE
daemonset.apps/speaker 2 2 2 2 2 kubernetes.io/os=linux 8m35s
NAME READY UP-TO-DATE AVAILABLE AGE
deployment.apps/controller 1/1 1 1 8m35s
NAME DESIRED CURRENT READY AGE
replicaset.apps/controller-64f86798cc 1 1 1 8m35s
Documentation says:
The installation manifest does not include a configuration file.
MetalLB’s components will still start, but will remain idle until you
define and deploy a configmap
So we go to the page related to setting up the configmap, I used a simple layer 2 configuration and created a metallb-configmap.yaml file:
apiVersion: v1
kind: ConfigMap
metadata:
namespace: metallb-system
name: config
data:
config: |
address-pools:
- name: default
protocol: layer2
addresses:
- 192.168.1.240-192.168.1.250
Once you've done it, you'll need to apply this configmap:
kubectl apply -f metallb-configmap.yaml
Then simple example with nginx deployment:
kubectl create deploy nginx --image=nginx --replicas=1
And service:
kubectl expose deploy nginx --port=80 --type=LoadBalancer
And check if received an external IP address:
kubectl get svc
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
nginx LoadBalancer 10.101.83.208 192.168.1.241 80:31836/TCP 8m44s
Check this works:
curl -L 192.168.1.241

Let me know if you have different results.
