How to manage Kubernetes' LoadBalancer with Terraform

I use Terraform to provision and manage a Kubernetes cluster on DigitalOcean. Specifically I use DigitalOcean Terraform provider.

It is pretty straight forward to create a cluster.

At the same time DigitalOcean suggests to manage Kubernetes’ Load Balancers with kubectl. Meaning when I install ingress-nginx with kubectl, DigitalOcean will automatically create a LoadBalancer. However that particular LoadBalancer is not defined in a terraform file. Meaning I cannot get it’s IP(for setting a DNS), scale it or delete it.

Another problem is, if I first create a LoadBalancer with terraform. I still need an Ingress Controller. Now I install ingress-nginx with kubectl which will override the LoadBalancer previously created with terraform.

The question is: How to manage Kubernetes LoadBalancer with Terraform on DigitalOcean? Any examples or help is much appreciated.

Hi there,

There has been a similar issue raised on the official DigitalOcean Terraform provider repo here:

You can follow the example here:

Along with the changes from this PR here to get the IP address of the load balancer:

Hope that this helps.
