I don't know if I'm doing something wrong but it would not work for me.
Consider this fabfile.py:
from fabric.api import *
@hosts('1.1.1.1')
def deploy_one():
run('this on 1')
@hosts('2.2.2.2')
def deploy_two():
run('that on 2')
def deploy():
deploy_one()
deploy_two()
Well, if I run ``fab deploy`` it will complain about missing host
definition for the task ``deploy``:
$ fab deploy
No hosts found. Please specify (single) host string for connection:
I have looked all over the web only to find everyone would be running
``fab deploy_one deploy_two``. Which is not what I want.
How can I make the script work?
Thanks
