@hosts(user1@host)
def dothis()
    with change_user(user2):<-- this is what i want to do change user to user2 who is a system user with no password and can't login via ssh
        with cd('~'): <-- cd to users ~
            sometask() <-- run this as user2

您可以通过使用sudo（）允许简单切换，并让它为用户提供一个变量，您可以使用您想要创建的目标上下文管理器进行切换。这看起来有点像：

def set_user(user):
    #Make into context manager
    env.custom_user = user

def bar():
    with set_user("foo"):
        execute("sometask")

def sometask():
    sudo("command", user=env.custom_user)

fabric run命令作为系统用户
