使用Hashicorp Vault和Ansible - 插件设置

标签: ansible hashicorp-vault

我想使用Hashicorp Vault和Ansible来检索我将在Ansible playbook中使用的用户名/密码。

Vault已设置 - 我创建了一个秘密。整合两者的步骤是什么?关于插件的文档并不是很好。我尝试从ansible文件查找,但这有效,但如何使用第三方插件?有人可以帮助我遵循以下步骤吗?

  1. 安装插件pip install ansible-modules-hashivault
  2. https://github.com/jhaals/ansible-vault有什么不同 2.a环境变量(VAULT ADDR& VAULT TOKEN)我放在哪里?
  3. ansible.cfg更改为指向位于"插件"中的vault.py我的Ansible项目的文件夹
  4. 要测试基本集成,我可以使用以下playbook吗? https://pypi.python.org/pypi/ansible-modules-hashivault

    - hosts: localhost
        -tasks:
           - hashivault_status:
             register: 'vault_status'
    
  5. 试过这个,但我明白了:

由于你在帖子中放了这么多鸡蛋,我不知道问题的真正含义,这里有一些东西可以让你使用原生查找插件和jhaals/ansible-vault

  • 您可以在当前目录中创建lookup_plugins并将vault.py保存在内部;

  • VAULT_ADDRVAULT_TOKEN环境变量就像您在脚本中看到的那样;

下面的Bash脚本(它使用screenjq,您可能需要安装它们)以开发模式运行Vault,设置机密,并运行Ansible playbook,通过两次查询查询机密插件:

#!/bin/bash
set -euo pipefail

export VAULT_ADDR=http://127.0.0.1:8200

if [[ ! $(pgrep -f "vault server -dev") ]]; then
    echo \"vault server -dev\" not running, starting...
    screen -S vault -d -m vault server -dev
    printf "sleeping for 3 seconds\n"
    sleep 3
else
    echo \"vault server -dev\" already running, leaving as is...
fi

vault write secret/hello value=world excited=yes
export VAULT_TOKEN=$(vault token-create -format=json | jq -r .auth.client_token)
ansible-playbook playbook.yml --extra-vars="vault_token=${VAULT_TOKEN}"

playbook.yml

---
- hosts: localhost
  connection: local
  tasks:
    - name: Retrieve secret/hello using native hashi_vault plugin
      debug: msg="{{ lookup('hashi_vault', 'secret=secret/hello token={{ vault_token }} url=http://127.0.0.1:8200') }}"

    - name: Retrieve secret/hello using jhaals vault lookup
      debug: msg="{{ lookup('vault', 'secret/hello') }}"

最后你应该得到:

TASK [Retrieve secret/hello using native hashi_vault plugin] *******************
ok: [localhost] => {
    "msg": "world"
}

TASK [Retrieve secret/hello using jhaals vault lookup] *************************
ok: [localhost] => {
    "msg": {
        "excited": "yes",
        "value": "world"
    }
}

{Vault}中提取了world这个词。
