Ansible 安全 之加密主机清单

Ansible 安全 之【加密主机清单】

创建ansible-vault加密工具

ln -s /usr/local/python3/bin/ansible-vault /usr/bin/ansible-vault

设置主机清单配置文件密码

ansible-vault encrypt /etc/ansible/hosts
# New Vault password: 
# Confirm New Vault password: 
# Encryption successful

加密后查看主机清单配置文件，无法查看

cat /etc/ansible/hosts 
# $ANSIBLE_VAULT;1.1;AES256
# 37333832643234663939653731373066323563313433316363326561656637633632333861393665

命令行测试

# 测试(无法运行命令,无法访问主机清单配置文件)
ansible all -a hostname
# [WARNING]:  * Failed to parse /etc/ansible/hosts with yaml plugin: Attempting to decrypt but no vault secrets found
# [WARNING]:  * Failed to parse /etc/ansible/hosts with ini plugin: Attempting to decrypt but no vault secrets found
# [WARNING]: Unable to parse /etc/ansible/hosts as an inventory source
# [WARNING]: No inventory was parsed, only implicit localhost is available
# [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'

# 正常在命令行运行命令,需要加参数--ask-vault-pass,并且输入密码
ansible all -a hostname --ask-vault-pass 
# Vault password:

剧本测试

# 编写剧本
vim abc.yml 
- hosts: all
  tasks:
  - name: hostname
    shell: hostname

# 测试剧本(无法执行剧本,无法访问主机清单配置文件)
ansible-playbook abc.yml
