Re: [Fab-user] execute command depending on role

[Stroehmann, James]

[Cut and paste error corrected]

 

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')

 

----

 

# fab –R prodmail OOpsWorks

address@hidden Executing task 'OOpsWorks'

address@hidden run: uname -n

address@hidden out: mail1.tld

 

address@hidden Executing task 'OOpsWorks'

address@hidden run: uname -n

address@hidden out: mail2.tld

 

Done.
