Re: Can't add custom service on server side via zerodeploy

[Tomer Filiba]

you can't "zero deploy" to any service other than the slave service. that's mostly due to technical limitations -- you have to send the service code to the other side first, which makes life more complicated. if you want to add a patch, e.g., implement CustomDeployServer(files_to_copy) please do so and send me a pull request

Hi,
I would like to use RPyC service model while deploying new server via zerodeploy,
however I don't see any API available for this. Tried to add my service TestService to DeployedServer.connect() but it doesn't work.
Am I missing something?
Appreciate your help.

class TestService(Service):
  def on_connect(self):
    pass
  def on_disconnect(self):
    pass

  def exposed_GetHostName(self): # this is an exposed method
    with open("/etc/hostname","r") as hostnameFile:
      return "Remote hostname is: "%hostnameFile.read().strip()

  def get_question(self):  # while this method is not exposed
    return "what is the airspeed velocity of an unladen swallow?"

def connectToServer(hostName, userName):
  print "Connecting to '%s' with user name '%s' ..."%(hostName, userName)
  mach = SshMachine(hostName, user=userName)
  print "Connected!"
  print "Remote date and time: [ %s ]"%( mach["date"]().strip() )
  print "Deploying RPyC..."
  server = DeployedServer(mach)
  print "RPyC server deployed and started. Connecting to local RPyC..."
  conn1 = server.connect(TestService)
  print "SSH tunnel to local RPyC server on '%s' created " % (hostName)
  return server, conn1

def run():
  serverConn, rpyc_conn = connectToServer(hostName="server-name", userName="user")
  print "server returned:"+rpyc_conn.root.GetHostName()
if __name__ == "__main__":
  run()

Error:
