environment-variables - Ansible - 包括来自外部 YML 的环境变量

Question

我试图将所有环境变量存储在一个名为 variables.yml 的文件中，如下所示:

---
doo: "external"

然后我有一个这样的剧本:

---
- hosts: localhost
  tasks:
    - name: "i can totally echo"
      environment:
          include: variables.yml
          ugh: 'internal'
      shell: echo "$doo vs $ugh"
      register: results

    - debug: msg="{{ results.stdout }}"

回显的结果是' vs internal'。

我怎样才能改变它，使结果是'external vs internal'。非常感谢!

Answer 1

假设名为variables.ext 的外部变量文件结构如下

---
EXTERNAL:
  DOO: "external"

比，根据Setting the remote environment和 Load variables from files, dynamically within a task一个小测试可能看起来像

---
- hosts: localhost
  become: false
  gather_facts: false

  tasks:

  - name: Load environment variables
    include_vars:
      file: variables.ext

  - name: Echo variables
    shell:
      cmd: 'echo "${DOO} vs ${UGH}"'
    environment:
      DOO: "{{ EXTERNAL.DOO }}"
      UGH: "internal"
    register: result

  - name: Show result
    debug:
      msg: "{{ result.stdout }}"

导致输出

TASK [Show result] ********
ok: [localhost] =>
  msg: external vs internal
