## Definition
|
||
Declarative Configuration（声明式配置）是一种配置管理方法，通过描述系统的期望状态（what）而非具体步骤（how）来定义基础设施和应用配置。
|
||
|
||
## Key Characteristics
|
||
- 定义期望的结果状态，而非实现步骤
|
||
- 工具负责计算如何达到期望状态
|
||
- 幂等性：多次应用产生相同结果
|
||
- 易于理解和版本控制
|
||
|
||
## Examples
|
||
- Kubernetes YAML 配置
|
||
- Terraform HCL 配置
|
||
- Docker Compose 配置
|
||
- Ansible Playbook
