How can I get into a Packet.net node managed by Docker Cloud?
Packet.net copies SSH keys into the created device, so you can upload to Packet.net's portal your own SSH public key and then SSH into the node with the user
root. You can also get into the node with Packet's console. You can also use a container to copy your SSH keys into the node, as explained in SSHing into a Docker Cloud-managed node.
