Uploads ssh-keys to an instance

gce_ssh_setup(instance, key.pub = NULL, key.private = NULL,
  ssh_overwrite = FALSE, username = Sys.info()[["user"]])



Name of the instance of run ssh command upon


The filepath location of the public key


The filepath location of the private key


Will check if SSH settings already set and overwrite them if TRUE


The username you used to generate the key-pair


TRUE if successful


This loads a public ssh-key to an instance's metadata. It does not use the project SSH-Keys, that may be set separately.

You will need to generate a new SSH key-pair if you have not connected to an instance before.

Instructions for this can be found here: https://cloud.google.com/compute/docs/instances/connecting-to-instance. Once you have generated run this function once to initiate setup.

If you have historically connected via gcloud or some other means, ssh keys may have been generated automatically.

These will be looked for and used if found, at file.path(Sys.getenv("HOME"), ".ssh", "google_compute_engine.pub")
