This should work for you.  I think the main problem is how you check the that the host_string is in the roledefs dict.

 

from fabric.api import env, run, task

 

env.roledefs = {

    'prodmail': ['address@hidden', 'address@hidden'],

    'prodweb': ['address@hidden', 'address@hidden']

}

 

@task

def OOpsBroke():

    if env.host_string in env.roledefs['prodmail']:

        print 'uname -n', env.host_string

    elif env.host_string in env.roledefs['prodweb']:

        print 'uname -a', env.host_string

    else:

        print 'uname -v', env.host_string

I am trying to get fabric to execute different commands based on which role they are placed in, but my if statement is not working as expected. In the fabfile below, the first task works (OOpsWorks) but the second only executes the “else”:

from fabric.api import *

 

env.roledefs = {

    'prodmail': ['address@hidden, 'address@hidden’],

    'prodweb': ['address@hidden', 'address@hidden']

}

 

@task

def OOpsWorks():

    run('uname -n')

 

@task

def OOpsBroke():

    if env.host_string in env.roledefs == 'prodmail':

       run('uname -n')

    elif env.host_string in env.roledefs == 'prodweb':

       run('uname -a')

    else:

       run('uname -v')
