gce_ssh_addkeys function

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

Returns

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

## Not run:

  
  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")
## End(Not run)
