Re: [Fab-user] combining multiple tasks on multiple targets into a single function

[Thomas GRATTON]

Hi there,

Before, thanks to Fabric developpers, keep da good work up ;)

I'm using Fabric & Python since 1 week, essentialy to grab informations 
on my Linux servers.

Chris, first :

You've to use RSA public keys. Then yu'll able to use SSH as this :

from fabric.api import *

env.roledefs['debian_sarje'] = ['myserver1','myserver2','myserver3'...]
env.roledefs['redhat_as_6'] = ['myserver5','myserver8','myserver0'...]

@roles('redhat_as_6','debian_sarje')

my_function():

        # verbose or no
        with settings(
        hide('warnings', 'running', 'stderr','stdout'),
        warn_only=False
        ):

                # grab info
                hostname = run('hostname -s')
                kernel = run('uname -r')

        ...

I must say that the best thing is to read this before scripting :

My two cents... Hope it'll help you ;)

PS : sorry for bad english -__-
