none backend: documentation doesn't describe authentication

[pvgoran]

The current version of manual only mentions that deployment.targetHost needs to be set in order to deploy to a NixOS machine (none backend). It's unclear how I can supply nixops with authentication information so that it could log into the machine to perform deployment. Also, it's unclear whether nixops will use the the provided authentication method (whatever it is) forever, or it will create and use its own SSH key pair.

nixops will generate its own keypair to get into the machine, but that key isnt trusted out of the box, so you need to either have an ssh-agent working or maybe password auth works

[pvgoran]

I have trouble understanding this. What are the actions that I need to perform to make the machine accessible to and manageable by nixops?

[cleverca22]

for the first deploy, run ssh-agent and ssh-add a key that can ssh into root

for all future deploys, nixops added its own key and can just get in
