我编写了一个剧本,从 git 三个 repo 克隆并从源代码编译它们。
每当我配置使用该剧本的机器时,无论存储库的本地副本是否已更新,都会克隆存储库。
我希望 git clone 仅在第一次发生,而在运行剧本的其余时间,我希望 Ansible 跳过这一步。
我已经在 Ansible 文档中阅读了有关“本地事实”的内容,但我很难理解应该如何实现它。
这是我写的剧本:

非常感谢您的帮助。

您可以使用统计模块
你可能想做这样的事情:
- name: Check if repository is checked out.
stat: path={{ kafkacat_installdir }}/kafkacat
register: git_dir
- name: Git clone kafkacat
git: repo=git://github.com/company/kafkacat.git
dest={{ kafkacat_installdir }} accept_hostkey=yes force=yes
tags: kafkacat
when: git_dir.stat is defined and git_dir.stat.isdir
