【问题描述】：
我的问题有点棘手。我的任务是为 Ruby 中的系统构建（不是我开发的）制作部署脚本。这个项目已经有一个 capistrano 部署，只要机器有以前的设置，它就可以正常工作。我的任务是在不触及 capistrano 部分的情况下自动执行此设置。由于我对 capistrano 一无所知，也没有多少时间去做，所以我决定使用 ansible。
这个想法是运行 ansible 脚本，这会设置机器并调用 capistrano 来部署项目。我尝试了以下任务，但都产生了一些错误：

有没有办法从 ansible 调用 capistrano 或者无法调用？
编辑： generic_production 是一个使用 MACHINE 作为目标的部署脚本。
【问题讨论】：
-
Capistrano 通常需要在本地机器上运行，而 Ansible 就是在远程机器上运行命令。你确定这是实用的吗？我不确定
MACHINE是什么，看起来不标准。 -
我认为这不实用。理想情况下，我会用 ansible 重新设计所有东西。但我没有时间做这件事，也没有时间学习如何使用 capistrano 进行设置。有没有办法让 capistrano 在本地运行？
-
我是说 Capistrano 本质上在本地运行，通过 SSH 执行远程命令。 Ansible 类似。通过 Ansible 运行 Capistrano 意味着运行...从远程服务器到远程服务器的远程命令？它们是试图完成相同工作的两种工具。
