安塞 bool : Git module clone of repository while re-run is throwing exception

Question

我正在使用 ansible-playbook 来设置服务器，该服务器正在从 github 克隆存储库。当我重新运行剧本时，我收到异常 msg: fatal: 目标路径 '/webapps/........' 已经存在并且不是空目录。

TASK: [web | Setup the Git repo] **********************************************
failed: [192.168.1.96] => {"cmd": "/usr/bin/git clone --origin origin --branch master https://github.com/....../......git /webapps/....../...../....", "failed": true, "rc": 128}
stderr: fatal: destination path '/webapps/..../..../....' already exists and is not an empty directory.

msg: fatal: destination path '/webapps/..../..../....' already exists and is not an empty directory.

FATAL: all hosts have already failed -- aborting

剧本

- name: Setup the Git repo
  git: repo={{ git_repo }}
       version="{{ git_branch }}"
       dest={{ project_path }}
       accept_hostkey=yes
       force=yes
  when: setup_git_repo is defined and setup_git_repo
  tags: git

- name: Delete all .pyc files
  command: find . -name '*.pyc' -delete
  args:
    chdir: "{{ project_path }}"
  tags: git

如果文件已克隆并存在于服务器中，如何跳过此步骤(或)覆盖文件。

我仍然遇到这个问题，并找到了以下(hacky)解决方法:

- name: Setup the Git repo
  git: repo={{ git_repo }}
       version="{{ git_branch }}"
       dest={{ project_path }}
       accept_hostkey=yes
       force=yes
  when: setup_git_repo is defined and setup_git_repo
  tags: git
  ignore_errors: yes
  register: clone_command_res
  
- name: Only allow the expected failure
  assert:
    that: "not clone_command_res['failed'] or 'already exists and is not an empty directory' in clone_command_res['msg'].lower()"

在后面，错误消息可能会有所不同，具体取决于您之前的状态(例如我的错误消息是存储库中存在本地修改)或更糟糕的是，git和/或ansible版本。无论如何，只需包含预期的错误消息(有点像 try/catch)。

虽然如果 ansible git 模块中有针对这种情况的选项会更好，但现在应该可以了。
