If you want to change the external IP of the Load Balancer, you can associate a floating IP to the Load Balancer in the SysEleven Stack dashboard. A newly created Load Balancer already has an IP associated, to disassociate it open the menu
Project -> Network -> Load Balancers and click on
Disassociate Floating IP:
Afterwards you can associate another IP by clicking on
Associate Floating IP in the same menu. This will trigger a popup, where you can either select an already existing floating IP or a floating IP pool:
Every LoadBalancer automatically also receives a SecurityGroup that opens the necessary ports for this Load Balancer up. This SecurityGroup can also be configured to only allow certain source IP ranges by setting the
loadBalancerSourceRanges field of a service.
For more information see Configure Your Cloud Provider's Firewalls.
Note that because of a limitation in Kubernetes, updating or adding this field after the creation of a Load Balancer service is currently not possible.
This can have multiple reasons. Typical problems are
kubectl port-forward $PODNAME 8080:80(port might differ) and check if you can reach your application on Port 80.
kubectl get svc.
