python - Wait until process in remote server finishes using Fabric -


setup

i using fabric kick off process on remote server. local server executes python file runs 3 functions in sequence: 1st , 3rd in local server , 2nd in remote server, follows.

local_file.py

local_function_1() remote_function() local_function_2()

the remote function 1 specified in local fabfile, follows.

fabfile.py

from fabric.api import * @hosts(remote_server) def remote_function():     run('python function_on_remote_server.py')

question

local_function_2 should run after remote_function has finished running, unsure how accomplish this.

i have considered (1) waiting fixed number of seconds before local_function_2 runs , (2) adding intermediary local function checks existence of output remote_function before running local_function_2.

how can delay execution of function on local server until after function on remote server has finished running?

one way change way you're calling remote_function, , use fabric execute instead.

from fabric.api import execute  local_function_1() execute(remote_function) local_function_2()

execute should block until tasks complete.

for more info, see intelligently executing tasks execute.
