本章主要介绍如何对ansible的 playbook 进行加密。
前面写了许多playbook,这些playbook都是以明文的方式存在的,有时想对这些playbook进行加密,可以使用ansible-vault命令来实现。本章实验都在/home/demo6下操作,先把 demo6目录创建出来并把ansible.cfg 和 hosts拷贝
[bdqn@RHEL813 ~]$ mkdir demo6
[bdqn@RHEL813 ~]$ cp ansible.cfg hosts demo6/
[bdqn@RHEL813 ~]$ cd demo6
[bdqn@RHEL813 demo6]$ ls
ansible.cfg hosts
[bdqn@RHEL813 demo6]$
创建test1.yaml,内容如下。
[bdqn@RHEL813 demo6]$ cat test1.yaml
---
- hosts: server2
gather_facts: false
vars:
aa: haha001
tasks:
- name: 打印一个变量
debug: msg="{{aa}}"
[bdqn@RHEL813 demo6]$
ansible‐vault encrypt file
[bdqn@RHEL813 demo6]$ ansible-vault encrypt test1.yaml
New Vault password:
Confirm New Vault password:
Encryption successful
[bdqn@RHEL813 demo6]$
[bdqn@RHEL813 demo6]$ cat test1.yaml
