ruby - 如何从ansible脚本调用capistrano

Question

我的问题有点棘手。我被赋予了一项任务，即用 Ruby(不是我开发的)为系统构建制作部署脚本。这个项目已经有一个 capistrano 部署，只要机器有以前的设置就可以正常工作。我的任务是在不接触 capistrano 部分的情况下自动执行此设置。由于我不了解 capistrano 并且没有时间去做，所以我决定使用 ansible。

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:

- name: Run cap
  shell: "cap generic_production deploy"
  environment:
    MACHINE: localhost
  args:
    chdir: /home/{{ansible_user_id}}/project

有没有办法从 ansible 调用 capistrano 或无法完成？

编辑:generic_production 是一个使用 MACHINE 作为目标的部署脚本。

Answer 1

如果 ansible playbook 从您正常运行 cap 的目录运行，这对我有用。

- name: capistrano deploy
  local_action: shell cap generic_production deploy
  become: false
