I want to know whether this is a default behaviour or something wrong with my setup.
I have 150 workers running on kubernetes.
I made a set of kubernetes workers (10 workers) run only a specific deployment using nodeSelector, I created a service (type=LoadBalancer) for it, when the Load Balancer was created all the 150 workers of Kubernetes were registered to the Load Balancer, while I was expecting to see only this set of workers (10 workers) of this deployment/service.
It behaved the same with
kind: Service apiVersion: v1 metadata: name: my-service spec: selector: app: my-app ports: - port: 8080 type: LoadBalancer
and the deployment
apiVersion: apps/v1 kind: Deployment metadata: name: my-app spec: selector: matchLabels: app: my-app replicas: 10 template: metadata: labels: app: my-app spec: containers: - name: master-api image: private/my-app:prod resources: requests: memory: 8000Mi ports: - containerPort: 8080 nodeSelector: role: api
I was already labeled 10 workers nodes with the label
the 10 run only pods of this deployment, and no other worker is running this service
I also don't have another service or container using port 8080
