Control plane firewalls for DigitalOcean Kubernetes are now in general availability. Control plane firewalls restrict access to your cluster’s API server to a set of allowed IP addresses. Worker node IPs are automatically kept in sync as nodes scale up or down.
You can enable control plane firewalls using the DigitalOcean API, doctl, or Terraform.
