Instance Method Details

#rcp(opts) ⇒ Boolean

TODO:

This is damn ugly, because we ssh in as vagrant, we copy to a temp path then move it later. Its slow and brittle and we need a better solution. Its also very Linux-centrix in its use of temp dirs.

Transfer files to a host in the NodeSet.

Parameters:

  • opts (Hash) —

    options

Returns:

  • (Boolean) —

    returns true if command succeeded, false otherwise

# File 'lib/rspec-system/node_set/vsphere.rb', line 168

def rcp(opts)
  dest = opts[:d].name
  source = opts[:sp]
  dest_path = opts[:dp]

  # Grab a remote path for temp transfer
  tmpdest = tmppath

  # Do the copy and print out results for debugging
  ssh = RSpec.configuration.rspec_storage[:nodes][dest][:ssh]
  ssh.scp.upload! source.to_s, tmpdest.to_s, :recursive => true

  # Now we move the file into their final destination
  result = run(:n => opts[:d], :c => "mv #{tmpdest} #{dest_path}")
  if result[:exit_code] == 0
    return true
  else
    return false
  end
end

#run(opts) ⇒ Hash

Run a command on a host in the NodeSet.

Parameters:

  • opts (Hash) —

    options

Returns:

  • (Hash) —

    a hash containing :exit_code, :stdout and :stderr
