Importer des modules de "fabric.api"

Définir une lite de machines
Globale:
env.hosts = ['host1', 'host2']
Roles:
from fabric.api import env
env.roledefs = {
'web': ['www1', 'www2', 'www3'],
'dns': ['ns1', 'ns2']
}
Via la ligne de commande "fab"
fab -H host1,host2 mytask fab -R roles
Ordre de préférence:
-Per-task, command-line host lists (fab mytask:host=host1) override absolutely everything else.
-Per-task, decorator-specified host lists (@hosts('host1')) override the env variables.
-Globally specified host lists set in the fabfile (env.hosts = ['host1']) can override
such lists set on the command-line, but only if you’re not careful (or want them to.)
-Globally specified host lists set on the command-line (--hosts=host1) will initialize the env variables, but that’s it.
