Is there a way to SSH to a kubernetes node droplet? When I created the kubernetes cluster there was no option to authorize an ssh key.

Hey,
first of all you need to give access ssh port on firewall section for your droplet/node.
After that you can reset your root password on droplets access tab.
When you get your new root password you can ssh to your node.

    Looks like this is the only way for now. Even though it would be hard to manually do this if you have a lot of nodes and if you recycle some regularly (scaling up/down on demand).

If you are looking to connect to a pod service in order to run commands, here is the syntax that worked for me:

kubectl exec pod-name -c container-name -i -t bash

I don’t believe there is - the tradeoff of a fully managed service is that you don’t get to log in and break their management.

Worker nodes are built on Droplets, but unlike standard Droplets, worker nodes are managed with the Kubernetes command-line client kubectl and are not accessible with SSH.

From https://www.digitalocean.com/docs/kubernetes/

I tried to connect thru load balancer IP but not success… it says “connection closed by remote”

If you want to copy files you can use kubectl cp command
