如何将ansible角色的`defaults/main.yml`文件拆分成多个文件？

Question

在某些安全角色(例如roles/my-role/)中,我有一些很大的默认变量文件(defaults/main.yml).我想把它main.yml分成几个较小的文件.有可能吗？

我试图创建的文件defaults/1.yml和defaults/2.yml,但他们不会被加载ansible.

Answer 1

由于Ansible 2.6很可能取代defaults/main/由目录:defaults/main.yml.(同样如此defaults/main/.)Ansible将加载defaults/main.yml该目录中的任何文件,因此您可以将文件命名为defaults/main/*.yml.

此功能已在ansible commit中实现*.yml.

如果您不使用 2.6（您可能应该使用，但我知道这并不总是一个选项），那么您可能会发现include_vars 很有用。

- name: Include vars of stuff.yaml into the 'stuff' variable (2.2).
  include_vars:
    file: stuff.yaml
    name: stuff

- name: Conditionally decide to load in variables into 'plans' when x is 0, otherwise do not. (2.2)
  include_vars:
    file: contingency_plan.yaml
    name: plans
  when: x == 0

- name: Load a variable file based on the OS type, or a default if not found. Using free-form to specify the file.
  include_vars: "{{ item }}"
  with_first_found:
    - "{{ ansible_distribution }}.yaml"
    - "{{ ansible_os_family }}.yaml"
    - default.yaml

- name: Bare include (free-form)
  include_vars: myvars.yaml

- name: Include all .json and .jsn files in vars/all and all nested directories (2.3)
  include_vars:
    dir: vars/all
    extensions:
        - json
        - jsn

- name: Include all default extension files in vars/all and all nested directories and save the output in test. (2.2)
  include_vars:
    dir: vars/all
    name: test

- name: Include default extension files in vars/services (2.2)
  include_vars:
    dir: vars/services
    depth: 1

- name: Include only files matching bastion.yaml (2.2)
  include_vars:
    dir: vars
    files_matching: bastion.yaml

不过请注意，这是一个任务指令。它不像能够将它包含到默认文件本身那样简洁。
