Fabric takes the env.hosts variable is taken into consideration just
prior to executing a task. So, if you move your env.hosts assignment
to another task and execute that before you execute "doit" then it
will work:
def setup():
env.user = "keyes"
env.hosts = ['example.com']
def doit():
run('ls')
What fabric does, among other things, is that it wraps your task in a
loop that sets env.host_string to each of the hosts in turn. Or
something with a similar effect. And then runs the task for each host.
