Add SSH details to a gce_instance

Add SSH details to a gce_instance

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

Arguments

instance	The gce_instance
key.pub	filepath to public SSH key
key.private	filepath to the private SSK key
username	SSH username to login with
overwrite	Overwrite existing SSH details if they exist

Value

The instance with SSH details included in $ssh

Details

You will only need to run this yourself if you save your SSH keys somewhere other than $HOME/.ssh/google_compute_engine.pub or use a different username than your local username as found in Sys.info[["user"]], otherwise it will configure itself automatically the first time you use gce_ssh in an R session.

If key.pub is NULL then will look for default Google credentials at file.path(Sys.getenv("HOME"), ".ssh", "google_compute_engine.pub")

Examples

if (FALSE) {

  library(googleComputeEngineR)

  vm <- gce_vm("my-instance")

  ## if you have already logged in via gcloud, the default keys will be used
  ## no need to run gce_ssh_addkeys
  ## run command on instance            
  gce_ssh(vm, "echo foo")


  ## if running on Windows, use the RStudio default SSH client
  ## e.g. add C:\Program Files\RStudio\bin\msys-ssh-1000-18 to your PATH
  ## then run: 
  vm2 <- gce_vm("my-instance2")

  ## add SSH info to the VM object
  ## custom info
  vm <- gce_ssh_setup(vm,
                      username = "mark",
                      key.pub = "C://.ssh/id_rsa.pub",
                      key.private = "C://.ssh/id_rsa")

  ## run command on instance            
  gce_ssh(vm, "echo foo")
  #> foo

  ## example to check logs of rstudio docker container
  gce_ssh(vm, "sudo journalctl -u rstudio")
