DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service. Deploy Kubernetes clusters with a fully managed control plane, high availability, autoscaling, and native integration with DigitalOcean Load Balancers and volumes. DOKS clusters are compatible with standard Kubernetes toolchains and the DigitalOcean API and CLI.
Starting with DigitalOcean Kubernetes 1.19, the NodePort range 30000-32767 is not open by default anymore. Instead, a new controller automatically manages access through the firewall based on the Services of type NodePort currently defined in the cluster.
Consult the worker node firewalls documentation for details.
