I've created a docker-machine on AWS EC2 using:
$ docker-machine create --driver amazonec2 aws01
in the terminal of my Ubuntu desktop computer. Now I want to reconnect/reattach myself to this machine on my laptop using
docker-machine create \ --driver generic \ --generic-ip-address=<your_ip> \ --generic-ssh-key ~/.ssh/id_rsa \ vm
which I saw in this question.
I don't know if this is even working or if it is the correct way to reattach/reconnect to a docker-machine. But what I want to know for now is what is supposed to go in the --generic-ssh-key parameter? Which key should I provide here?
