Ansible playbook - 环境变量 [英] Ansible playbook - environment variables

问题描述

我正在尝试(新手)设置一个剧本，它将使用查找插件从保险库中获取秘密(https://github.com/jhaals/ansible-vault)，但每次都会因为缺少环境变量而失败.任何人都可以帮忙吗?感谢您的帮助.

I am trying (newbie) to setup a playbook, which will use lookup plugin to fetch secrets from vault (https://github.com/jhaals/ansible-vault), but it will fail on missing environment variables every time. Can anyone help? Thanks for the help.

查找模块中有条件:

url = os.getenv('VAULT_ADDR')
        if not url:
            raise AnsibleError('VAULT_ADDR environment variable is missing')

剧本:

---
- hosts: localhost
  vars:
    vault1_env:
      VAULT_ADDR: https://localhost:8200/
      VAULT_TOKEN: my-token-id
      VAULT_SKIP_VERIFY: True

  tasks:
     - shell: echo VAULT_ADDR is $VAULT_ADDR, VAULT_TOKEN is $VAULT_TOKEN, VAULT_SKIP_VERIFY is $VAULT_SKIP_VERIFY
       environment: "{{ vault1_env }}"
       register: shellout
     - debug: var=shellout
     - debug: msg="{{ lookup('vault', 'secret/hello', 'value') }}"

输出:

推荐答案

这里你只是为 shell 模块设置环境变量，而不是为其他模块设置环境变量.如果要跨多个模块或整个主机使用变量，则应该 使用 environment 属性 在所有模块上，或在主机本身上，如下所示:

Here you are only setting environmental variables for the shell module, and not for the others. If you want to use variables across multiple modules, or for an entire a host, you should use the environment attribute on all of the modules, or on the host itself, something like this:

---
- hosts: localhost
  environment:
    VAULT_ADDR: https://localhost:8200/
    VAULT_TOKEN: my-token-id
    VAULT_SKIP_VERIFY: True
