ansibleVault加密字符串

我正在尝试加密一些密码,但想仅加密字符串的一部分而不是整个文件。因此,有一个命令 ansible-vault encrypt_string 可以为您提供加密的输出,但是当我将其添加到我的 .yaml 剧本中时,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

^

formatting is a little bit clunky with long strings

所以我尝试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 playbook 时:

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

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

TASK [Gathering Facts] ****************************************************************************************************************************
[WARNING]: There was a vault format error: Vault vaulttext format error: need more than 1 value to unpack

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

我尝试过以各种方式加密输出,但每次都因为这个问题或语法问题而失败。

当以从输出传递的方式放入时,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“|”收到此错误:

TASK [Gathering Facts] ****************************************************************************************************************************
fatal: [10.5.17.5]: FAILED! => {"msg": "AES256 343232643262663033646565616166633065663566366162386239316130323431316438393363383331346231343361386432666461646639386135666335380a373862336531613034393262653432313038303432636536313139353932356637343139393938666536383061383233613136643063353761386339323562640a3963306632393865613237666364386566623938356465336363613163646338 cipher could not be found"}

有什么想法吗?

最佳答案

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

仅供引用, https://github.com/ansible/ansible/blob/devel/lib/ansible/parsing/vault/init.py#L153 。 Vault 解析器正在寻找由 splitlines() 确定的位于第一行的 $ANSIBLE_VAULT;1.1;AES256(或类似的;vaulttext_envelope)。删除换行符打破了这一期望。

encrypt_string 的输出中,语法完全正确,可以粘贴到您的剧本中。 |(管道字符)在 yaml 中具有特殊含义。它是一个保留换行符的多行 block 。它应该是该行的最后一个字符。使用多行 block 时保持一致的缩进。因为剩余部分是在 https://github.com/ansible/ansible/blob/devel/lib/ansible/parsing/vault/init.py#L165join的,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有效:

ansible_password: !vault |

ansible_connection: winrm

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。我一般建议使用空格,但对于 python 和 yaml 则更是如此。如果您的编辑器/IDE 不支持语法突出显示,您应该切换到具有语法突出显示功能的编辑器/IDE。并获取某种 yaml linter。 yamllint.com 在短期内可以工作,但从长远来看,您应该获得一些自动的东西并内置到您的编辑器中。
