Why does fabric report "No hosts found"?

env.roledefs = {
    'seed': ['host1'],
    'peer': ['host2']
}

@roles('seed')
def test():
    pass

@roles('peer')
def test1():
    pass

def deploy():
    test()
    test1()

fab test, fab test1 - all ok

fab deploy:

No hosts found. Please specify (single) host string for connection:

Why ?

When calling test and test1 from deploy, the @roles are not taken into account. You should call the functions using execute(test) and execute(test1).

Because env.hosts is not set. Your test() functions do not use run() or any similar command that requires ssh connection, while deploy(), presumably, does().

Read these first:
