Salt Rosters

Salt rosters are pluggable systems added in Salt 0.17.0 to facilitate the salt-ssh system. The roster system was created because salt-ssh needs a means to identify which systems need to be targeted for execution.

Salt rosters是用于方便使用salt-ssh的可插拔系统。因为salt-ssh需要一个途径来知道哪些目标主机需要被执行命令。

Salt roster不需要用于标准的Salt,因为Master不需要知道目标主机，Salt Minion会自己检查

Roster配置文件位于/etc/salt/roster
