Ansible是一款无代理自动化工具，可用于配置管理（如安装Nginx、编辑配置文件）。2025年推出的Automation Platform 2.5具备统一UI和AI Lightspeed辅助功能。

When to Use

适用场景

Configuration Mgmt: Terraform creates the VM, Ansible installs the software inside it.
Agentless: No software to install on targets. Needs only SSH.
Network Automation: Configuring Routers/Switches.

配置管理：Terraform创建虚拟机后，Ansible负责在内部安装软件。
无代理架构：无需在目标主机上安装软件，仅需SSH即可。
网络自动化：配置路由器/交换机。

Best Practices (2025)

2025年最佳实践

Do:

Use Collections: The modern packaging format.
```
ansible.builtin
```
is better than short modules.
Use
ansible-lint
: Enforce best practices.
Idempotency: Ensure running a playbook twice produces the same result without errors.

Don't:

Don't use
shell
module: Unless absolutely necessary. Use specific modules (
```
user
```
,
```
file
```
,
```
apt
```
) for key tasks.

建议：

使用集合：采用现代化的打包格式，优先使用
```
ansible.builtin
```
而非短模块。
使用
ansible-lint
：强制遵循最佳实践。
幂等性：确保重复运行Playbook两次能得到相同结果且无错误。

不建议：

避免使用
shell
模块：除非绝对必要，核心任务应使用专用模块（如
```
user
```
、
```
file
```
、
```
apt
```
）。
