[Fab-user] problem with host_string/hosts (no hosts found)

[Wawrzek Niewodniczanski]

Hi,

For quite a long time I've been using various fabric based scripts.
Recently I hit very strange problem. Following short script
illustrates my issue.


#!/usr/bin/env python

import fabric
from fabric.api import env, run

env.hosts = ['localhost']

def test():
    print "Hosts:", env['hosts']
    print "Host_string", env['host_string']
    run('uname -a')


test()


And when I run It I got:

#>./fabric-min.py
Hosts: ['localhost']
Host_string None
No hosts found. Please specify (single) host string for connection: localhost
[localhost] run: uname -a


I copied content to fabfile.py and got the same:

#>fab test
Hosts: ['localhost']
Host_string None
No hosts found. Please specify (single) host string for connection: ^C
Stopped.

What do I  do wrong?


I run my tests at Ubuntu 14.04 LTS with
Python 2.7.6
Fabric 1.8.2
Paramiko 1.10.1


Thanks,
Wawrzek
