DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service that lets you deploy Kubernetes clusters without the complexities of handling the control plane and containerized infrastructure. Clusters are compatible with standard Kubernetes toolchains, integrate natively with DigitalOcean Load Balancers and volumes, and can be managed programmatically using the API and command line. For critical workloads, add the high-availability control plane to increase uptime with 99.95% SLA.
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.
