Example of creating a "supertask" in Fabric. The tasks spawns a couple of smaller tasks.

fabfile.py

from fabric.api import *
from __future__ import print_function

@task
def supertask():
    execute(create_user)
    execute(deploy)
    
    
@task
@host('root@host')
def create_user():
    print("Creating user...")
    

@task
@host('user@host')
def deploy():
    print("Deploying...")

run.sh

fab supertask
