Hi Wawrzek,
if you need to specify a host per task, I would recommend you to use the
@hosts decorator:
@hosts('localhost)
def test():
print "Hosts:", env['hosts']
print "Host_string", env['host_string']
run('uname -a')
Anyway, check out the documentation at
http://docs.fabfile.org/en/latest/usage/execution.html#how-host-lists-are-constructed
It explains how the hosts lists are constructed and how can you use it. I
usually use the -H flag in the fab command.
Regards
