Hi, I am very much new to kubernetes and trialing out the DO managed kubernetes product and have some questions that i need help with - struggling to find clear guides/docs describing the following:
doctl kubernetes cluster node-pool ...(or via the dashboard) to configure autoscaling? Do they have the same effect?
30000-32767is that correct?

Yes there is a difference between the two. The first command
kubectl autoscaleautomatically scales out your pod replicas of a given deployment. The second command automatically scales out the number of nodes in your cluster if your other ones resources are all used. doctl scales up nodes when there are pods stuck in pending due to the not enough resources. You can find documentation on the upstream autoscaler here: https://github.com/kubernetes/autoscaler/blob/master/cluster-autoscaler/FAQ.md#basics
Yes, container images need to be in a accessible registry that nodes can pull the image from in order to run them.
Yes that is correct. The range allowed here is the default nodeport range for kubernetes services. We are working on making this firewall configuration more flexible. https://kubernetes.io/docs/concepts/services-networking/service/#nodeport
