要检查目录是否存在，然后运行一些任务(例如创建目录)，请使用以下命令

- name: Check if output directory exists
    stat:
    path: /path/to/output
    register: output_folder

- name: Create output directory if not exists
    file:
    path: /path/to/output
    state: directory
    owner: user
    group: user
    mode: 0775
    when: output_folder.stat.exists == false

使用文件模块创建一个目录，并使用命令“ansible-doc file”获取文件模块的详细信息

这里有一个选项“state”解释:

If directory, all immediate subdirectories will be created if they do not exist, since 1.7 they will be created with the supplied permissions. If file, the file will NOT be created if it does not exist, see the [copy] or [template] module if you want that behavior. If link, the symbolic link will be created or changed. Use hard for hardlinks. If absent, directories will be recursively deleted, and files or symlinks will be unlinked. Note that file will not fail if the path does not exist as the state did not change. If touch (new in 1.4), an empty file will be created if the path does not exist, while an existing file or directory will receive updated file access and modification times (similar to the way touch works from the command line).

另外，在很多情况下，您需要创建多个目录，因此使用循环而不是为每个目录创建单独的任务是一个好主意。

- name: creates multiple directories in one task
  file:
    path: "{{ item }}"
    state: directory
  loop:
    - /srv/www
    - /dir/foo
    - /dir/bar

- file:
    path: /etc/some_directory
    state: directory
    mode: 0755
    owner: someone
    group: somegroup

这也是设置权限，所有者和组的方法。最后三个参数不是必须的。

我看到很多Playbooks的例子，我想提到Adhoc命令的例子。

$ansible -i inventory -m file -a "path=/tmp/ directory state=directory(我们可以用touch代替directory来创建文件)

只需要为特定的分配设置执行任务的条件

- name: Creates directory
  file: path=/src/www state=directory
  when: ansible_distribution == 'Debian'
