kubectl uses https for its communications. You can verify this by running kubectl in verbose mode. For example: kubectl get pods --v=6

Of course when you download the config file from digital ocean’s dashboard, that’s through an https connection, and if you use doctl it’s almost certainly the same.

If you have concerns about having admin power, you can also create a user with more limited access and use that user’s token instead of the admin token.

Hi there,

A quick update here in case that anyone comes across this in the future.

DigitalOcean has just announced that Control plane firewalls are now available in Early Availability.

The feature improves security and traffic for your cluster. Once enabled, only configured IP addresses, cluster worker nodes and workloads, and internal systems that manage the cluster (such as cluster upgrades) can access the control plane.

Existing open connections continue to work until they terminate. However, for WATCH requests, the API server enforces a maximum of 30 minutes for terminating the open connection.

For more information, see How to Add a Control Plane Firewall.
