Ansible - 創建多個文件夾，如果不存在

Question

目標：

• 創建多個目錄，如果它們不存在。
• 不要改變現有的文件夾

目前劇本的權限：

- name: stat directories if they exist 
    stat: 
    path: "{{ item }}" 
    with_items: 
    - /data/directory 
    - /data/another 
    register: myvar 

- debug: var=myvar.results 

- name: create directory if they don't exist 
    file: 
    path: "{{ item.invocation.module_args.path }}" 
    state: directory 
    owner: root 
    group: root 
    mode: 0775 
    with_items: "{{ stat.results }}" 
    # when: myvar.results.stat.exists == false 

的when說法是錯誤的。

我看了提供的例子; http://docs.ansible.com/ansible/stat_module.html。但是這隻適用於單個文件夾。

Ansible - 創建多個文件夾不改變以前存在的權限。

適合我。希望這對你有用，並試試。

- name: "Creating multiple by checking folders" 
    hosts: your_host_name 
    tasks: 
    - block: 
    - name: "Checking folders" 
     stat: 
     path: "{{item}}" 
     register: folder_stats 
     with_items: 
     - ["/var/www/f1","/var/www/f2","/var/www/f3","/var/www/f4"] 
    - name: "Creating multiple folders without disturbing previous permissions" 
     file: 
     path: "{{item.item}}" 
     state: directory 
     mode: 0755 
     group: root 
     owner: root 
     when: item.stat.exists == false 
     with_items: 
     - "{{folder_stats.results}}" 
...

使用Ansible模塊，你不需要或者檢查是否存在的東西沒有，你剛纔描述的理想狀態，所以：

- name: create directory if they don't exist 
    file: 
    path: "{{ item }}" 
    state: directory 
    owner: root 
    group: root 
    mode: 0775 
    with_items: 
    - /data/directory 
    - /data/another
