I have installed nginx-ingress from here: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nginx-ingress-with-cert-manager-on-digitalocean-kubernetes.
I have provisioned and configured my Load Balancer on my K8S cluster manually through the Control Panel.
I have created an appropriate Ingress object in my project. All this works. For a while.
As it turns out though, manual configurations on the Load Balancer don’t last long. The DO Cloud Control Manager (CCM) regularly updates the Load Balancer configuration from what it thinks would be best. That overrides my settings (specifically the port numbers) and does not work.
The way to properly configure the Load Balancer is apparently by annotating “the” LoadBalancer Service object. Seen here: https://docs.digitalocean.com/products/kubernetes/how-to/configure-load-balancers/
The problem is, that LoadBalancer service object is created by the nginx-ingress script above (named “nginx-ingress-ingress-nginx-controller”). I don’t own that, it is not managed by my k8s yaml scripts, it’s not even in my namespace.
What is the appropriate process here? Have I missed something? Do I need to own the LoadBalancer service? Should I just patch/overwrite it until it works? Do I leave the load-balancer-id annotation? Do I leave the helm annotations too? (I don’t use Helm) What happens if that script gets updated?

Hello @brautigamrobertgyula
All loadbalancers provisioned by kubernetes are managed by the Cloud Controller Manager(CCM) running on the master. Any manual modifications to the LB through the cloud panel will be overwritten by the CCM during its reconciliation process to ensure the LB is configured properly with the state defined by the kubernetes service.
In order to configure your LB you need to use kubernetes service annotations. For information on how to apply annotations, you can use the command:
kubectl annotate --help
Docs for DO service annotations can be found here: https://www.digitalocean.com/docs/kubernetes/how-to/configure-load-balancers/
Service annotations can also be found on our public github repository:
I hope this helps!
