Ansible - 如果不存在，则创建多个文件夹

Question

目标：

• 创建多个目录（如果它们不存在）。
• 不要更改现有文件夹的权限

当前的剧本：

- 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

when声明错误。

我看了一下提供的例子; http://docs.ansible.com/ansible/stat_module.html。但这仅适用于单个文件夹。

Answer 1

使用Ansible模块，您不需要检查是否存在某些内容，您只需描述所需的状态，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

Answer 2

Ansible - 创建多个文件夹而不更改以前存在的权限。

对我来说很好。希望这对您有用，只需尝试。

---
- 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}}"
...

从Ansible 2.5开始，应使用loop遍历列表，请参见https://docs.ansible.com/ansible/latest/user_guide/playbooks_loops.html#standard-loops

由于Ansible file模块是幂等的，因此您不必检查文件夹是否已存在。

例如：

- name: create backup directories
  file:
    path: "{{ item }}"
    state: directory
    owner: backup
    group: backup
    mode: 0775
  loop:
    - /backupdisk/certificates
    - /backupdisk/mysql
    - /backupdisk/wordpress

Answer 4

我的答案可能在每种情况下都行不通，但是如果您不提供任何选项，则ansible不会更改当前值。我已将其用于NFS挂载，其中NFS服务器上的权限有所不同。

- name: create directory if they don't exist
  file:
    path: "{{ item }}"
    state: directory
  with_items:
    - /share1
    - /share2
