使用命令-H时，可以在命令行上指定主机。
让我们说，你已经设置了一个env.hosts变量和一个主机列表。但有时，您需要仅在一个或两个主机上应用您的功能，并且您需要使用-H。
使用此参数时如何继续忽略env.hosts？我没有找到任何关于它的信息。这是实现这个目标的好方法吗？
答案 0 :(得分：1)
只有在未将env.hosts指定为命令行参数时才能填充env.hosts = env.hosts or ['host1', 'host2', 'host3']
，如：
-H这样设置CLI参数--hosts / env.hosts时，<?xml version="1.0" encoding="UTF-8"?>

已经包含加载fabfile时的值，而您没有覆盖其值。
如documentation中所述，从CLI指定的主机列表是优先顺序中的最新列表，因此可能被其他人覆盖。
