我正在尝试加密一些密码,但只想加密部分字符串而不是整个文件。所以有一个命令 ansible-vault encrypt_string 为您提供加密的输出,但是当我将它添加到我的 .yaml 剧本时,它无法解密。

用于加密简单密码的命令:

ansible-vault encrypt_string 'Test123!' --name 'ansible_password'

结果:

ansible_password: !vault | $ANSIBLE_VAULT;1.1;AES256 30333733643939646130396638646138636338636162316536313236666334656338306634353434 3132326265313639623039653261336265343733383730340a663565323932636138633365386332 36363534326263326633623238653464376637646632363839313464333830363436643561626534 6338613837393539350a383962663766373466376138376666393639373631313861663866333663 6137 Encryption successful

^

长字符串的格式有点笨拙

所以我试图将这个值放入我的剧本中,如下所示:

---
- name: Copy needed files to target machine
  hosts: prod
  vars:
          ansible_user: test_admin
          ansible_password: !vault $ANSIBLE_VAULT;1.1;AES256;303337336439396461303966386461386363386361623165363132366663346563383066343534343132326265313639623039653261336265343733383730340a663565323932636138633365386332363635343262633266336232386534643766376466323638393134643338303634366435616265346338613837393539350a3839626637663734663761383766663936393736313138616638663336636137
          ansible_connection: winrm
          ansible_winrm_transport: credssp
          ansible_winrm_server_cert_validation: ignore


  tasks:
  - name: Copy test
    win_copy:
       src: /etc/winmachines/hosts
       dest: C:\test\

然后我想用命令执行剧本:

ansible-playbook copy.yaml -i hosts.ini

结果:

PLAY [Copy needed files to target machine] ********************************************************************************************************

TASK [Gathering Facts] ****************************************************************************************************************************
fatal: [10.5.17.5]: FAILED! => {"msg": "Attempting to decrypt but no vault secrets found"}
        to retry, use: --limit @deleted

PLAY RECAP ****************************************************************************************************************************************
10.5.17.5                  : ok=0    changed=0    unreachable=0    failed=1

当我使用参数--ask-vault-password 运行剧本时:

ansible-playbook copy.yaml -i hosts.ini --ask-vault-pass

PLAY [Copy needed files to target machine] ********************************************************************************************************

TASK [Gathering Facts] ****************************************************************************************************************************

fatal: [10.5.17.5]: FAILED! => {"msg": "Vault vaulttext format error: need more than 1 value to unpack"}
        to retry, use: --limit @deleted

PLAY RECAP ****************************************************************************************************************************************
10.5.17.5                  : ok=0    changed=0    unreachable=0    failed=1

我试图以各种方式将输出加密,但每次由于此问题或语法问题而失败。

当从输出传递的方式输入时,我收到如下语法错误:

ERROR! Syntax Error while loading YAML.
  could not find expected ':'

The error appears to have been in : line 8, column 11, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

          $ANSIBLE_VAULT;1.1;AES256
          34323264326266303364656561616663306566356636616238623931613032343131643839336338
          ^ here

当所有内容都在同一行时,删除“|” 得到这个错误:

TASK [Gathering Facts] ****************************************************************************************************************************

有任何想法吗?

你的格式不正确。给出的格式ansible-vault encrypt_string 'Test123!' --name 'ansible_password'是您应该使用的格式。

作为参考, https://github.com/ansible/ansible/blob/devel/lib/ansible/parsing/vault/init .py #L153。Vault 解析器正在寻找$ANSIBLE_VAULT;1.1;AES256(或类似的;vaulttext_envelope)位于由 splitlines() 确定的第一行。删除换行符打破了这种期望。

在 的输出中encrypt_string,语法完全正确,可以粘贴到您的剧本中。(|管道字符)在 yaml 中有特殊的含义。它是一个保留换行符的多行块。它应该是该行的最后一个字符。使用多行块时保持一致的缩进。因为其余部分是joinhttps://github.com/ansible/ansible/blob/devel/lib/ansible/parsing/vault/init .py#L165编辑的,所以您不需要在密文本身中保留新行。

这意味着以下任何一项都应该起作用:

ansible_password: !vault |

    ansible_winrm_server_cert_validation: ignore

顺便说一句,选择制表符或空格,但不要同时使用两者。我一般推荐空格,但对于 python 和 yaml 更是如此。如果您的编辑器/ide 不做语法高亮,您应该切换到一个做的。并获得某种 yaml linter。yamllint.com 将在短期内工作,但从长远来看,你应该得到一些自动的东西并内置到你的编辑器中。
